Sunny Day
Well, RMT #1 for me on Smogon. Yay, I guess. My previous two teams were decent, netting me 40-65% win chances, but had enough problems that I didn't bother taking them to here: this one, I think, is better. I hope.
Anyways, I was reading through the Smogon site trying to improve a Trick Room team and I somehow wound up on the page for Pokemon that learned Fake Out. I also happened to be on the page for Explosion at the time... and it hit me. Shiftry: The only Pokemon in the game to get Fake Out and Explosion, with enough stats to do some serious damage with the latter. Focus Sash leads, I saw, would quail before its might. The only problem was the Speed.
Luckily, it had Chlorophyll, and this Sunny Day team was born.
At a glance:
The Lead: Shiftry @ Focus Sash
EVs: 4 HP 252 Atk 252 Spe
Ability: Chlorophyll
Nature: Hasty
Fake Out
Sunny Day
Explosion
Faint Attack
So yeah. Maybe this idea is flawed, but it seems to work pretty damn well in matches. Fake Out on turn one, Sunny Day on turn two, Explode the same turn your HP drops below 100% and Faint Attack until then. Faint Attack is there for those pesky Ghost-types who like to eat Explosions. If I see a lead that I know is probably carrying priority (e.g. Scizor, Machamp) I can forgo the Sunny Day and just explode, or switch out. EVs are obviously there to make the big kaboom hurt more. This would be incredibly epic in UU and I have no idea why no one's thought of it (and posted it) yet, but it still works decently in OU.
How it stacks up against other leads:
Azelf: Is dead. 100% chance. Unless, of course, he U-Turns to something else, in which case whatever he U-Turned to is dead. Sunny Day is up.
Aerodactyl: If he Taunts me he gets Stealth Rock up and I don't get Sunny Day up. Then he dies. If he decides to SR first instead of Taunting because he thinks I attack Sunny day **is** up.
Swampert: Exploding works like a charm. He can't Roar me out because if he does my entire team laughs in his face once Sunny Day is up. Which it will be if he Roars. Or does anything, really.
Metagross: Explosion might not kill it but Exeggutor sure as hell will the next turn. Sunny Day is up.
Jirachi: Abuse Faint Attack after a Sunny Day. If he kills me, I always have Exeggutor. If I get him below 60%, meaning two of Faint Attacks, an Explosion will guaranteeably finish him.
Infernape: Run like hell and switch to Cress.
Machamp: Machamp tends to carry Bullet Punch, forcing me to explode before I can Sunny Day. Good news is that he doesn't get to set anything up either.
Ninjask: Spam Faint Attack or switch to Drapion and watch him scream as I taunt him.
Roserade: Um... hope that the sleep misses. If it doesn't, it's just as though I exploded on a Ghost-type. Heatran can handle this guy.
Tyranitar: It's unfortunate that Sandstorm breaks my Sash. Then again, explosion puts a huge dent in this guy.
Scizor: Sunny Day, Explode, finish it with Exeggutor which is now set up.
Abomasnow: So Ice Shard means I can't put up Sunny Day right away. His hail inducer is dead. Who do you think won?
Special Sweeper: Heatran @ Life Orb
EVs: 4 Def 252 Spe 252 SpA
Ability: Flash Fire
Nature: Modest
Solarbeam
Substitute
Earth Power
Fire Blast
Substitute Heatran is a good idea, and hilariously enough it's my Heatran counter. Heatran coming in on my team inevitably wants to use either Fire Blast or Earth Power, which means either switch to Cress (if Heatran or Drapion is in) or Heatran (if Exeggutor or non-set-up Breloom is in). After I switch to Heatran, I immediately switch to Cress to avoid the obvious Earth Power. If it's a non-Scarf, it'll stay in despite the miss and Fire Blast, letting me T-Wave it. No Heatran is retarded enough to Earth Power Cress, meaning that I can heal up with Moonlight and switch back to Heatran for my Earth Power kill. Choice Scarf Heatran obviously runs like hell the instant I absorb their Fire Blast, and I get to paralyze whatever they bring in with Cress. If they have a Substitute Heatran and call that I'm going to run... my best option is trying to win a speed tie, which is less than ideal. Solarbeam is always a surprise for Swamperts who come in thinking they can wall Fire Blast and Earthquake me. Heatran always nets me at least 1 kill and usually 2-3. It's usually kept in reserve until Exeggutor is wounded because Eggy is the preferred switch-in after my Shiftry dies in order to let me abuse Chloropyhll. Fire Blast is there for STAB, though its inaccuracy displeases me. It absolutely slaughters Forretress and Scizor (once Cress has worked its magic). Metagross hates Fire Blast unless it carries Occa Berry, in which case it hates Earth Power. Fire Blast is also a pretty effective means of taking out Skarm, though few Skarms are stupid enough to switch in on Heatran unless they expect to absorb a probable Earth Power. Which is there for coverage. EVs are obvious.
Wall: Cresselia @ Heat Rock
EVs: 252 HP 252 Def 4 SpD
Ability: Levitate
Nature: Bold
Thunder Wave
Ice Beam
Moonlight
Sunny Day
I love Cress. It should be OU and no longer banned to that horrid land known as BL. At any rate, it makes things interesting for other teams. Fast sweepers such as Infernape and Gengar get paralyzed, which ruins their whole day. Not to mention that Sunny Day + Moonlight gives me reliable 66.7% healing. It also rips through Mences like nobody's business. They can't do jack to it and next turn they eat an Ice Beam to the face. Dragonite hates it almost as much. This is the number one reason why none of my opponents have ever gotten a single KO with Mence. CB Scizor also hates being paralyzed, though I have to watch out for Bug Bite. Gengar is trouble, but it too hates being paralyzed and can't OHKO. Togekiss is a pain in the ass but I can parahax it back.
Setup Sweeper: Exeggutor @ Life Orb
EVs: 4 Def 252 Spe 252 SpD
Ability: Chlorophyll
Nature: Modest
Grass Knot
Hidden Power Fire
Psychic
Sunny Day
Usually my switch after the lead, unless the lead was Abomasnow in which case I rather expect their team to be completely capable of killing Exeggutor. Chlorophyll is hilariously awesome. STAB Psychic rips through Infernape if Sunny Day is up (making me faster than it). Grass Knot 2HKOes TTar, though the odds that I get off 2 Grass Knots is unfortunately low due to Crunch. ScarfTar hates this set, though, if it's locked into something not named Crunch. Pert hates me. In fact, all bulky waters get 2HKOed here, though I prefer Heatran for taking them out. This guy's Sunny Day seems to last forever. Scizor and Metagross die rather horribly to HP Fire. Skarm gets killed too if Cress has already paralyzed it. Hippowdon is an OHKO to Grass Knot. EVs were obvious.
Wallbreaker: Drapion @ Leftovers
EVs: 252 HP 92 Atk 56 Def 108 Spe
Ability: Battle Armor
Nature: Impish
Crunch
Toxic
Ice Fang
Taunt
Liking this set reasonably well so far. Basically I noticed that my team was having some trouble with Gengar, Skarm, and Togekiss. Drapion ruins a phazing Skarm by Taunting it and then switching to Heatran. Unfortunately, the Skarm just runs away and I have to do it all again. Crunch is EV'd to guarantee a OHKO on Gengar, which works if Gengar doesn't sub. Ice Fang, Toxic, and Taunt in tandem absolutely slaughter Togekiss, which will always be outsped, assuming it's dumb enough to stay in (read: not too often). I went for Toxic over Toxic Spikes because Toxic Spikes statuses incoming counters to Breloom, which means it can't Spore them. This guy is actually a rather superb wallbreaker when it comes to things like Bliss, Clefable, and Cress, but it really can't do jack to Skarm.
Counter: Breloom @ Toxic Orb
EVs: 236 HP 248 Def 24 Spe
Ability: Poison Heal
Nature: Impish
Substitute
Leech Seed
Spore
Focus Punch
Standard SubSeeder. Damn, this thing is handy. Usually I keep it in reserve until everything else has scouted their team or I'm getting swept, which is admittedly rather rare. My team is pretty good at drawing out its counters, with the exception of Skarm (which is what Drapion is for). Breloom is good at sweeping the entire back half of most teams. Mence is never a problem. Breloom has really nice synergy with Drapion, each quite easily handling most of its counters.
Threat List stolen from someone else who probably also stole it from someone else so whatever:
Scizor:
-SD Variant: If I can get Sunny Day up, just go straight to Exeggutor and HP Fire for an OHKO. Otherwise paralyze it with Cress first and go to Heatran. Breloom also laughs at it.
-CB Variant: Same as above.
Salamence:
-MixMence: Cress.
-DD Bulky Mence: Cress.
-SpecsMence: Cress.
-CBMence: I'll give you one guess.
Rotom-A:
-Scarf: If it's caught on Overheat Heatran will stop it nicely. Otherwise Cress can paralyze it and then Heatran will stop it nicely.
-RestTalk: Breloom setup fodder.
-SubCharge Beam: Also hates being paralyzed and Metal Sound Heatran.
Tyranitar:
Just gonna get this out there; TTar is a problem because it takes out Sunny Day, which is nice to have around. It doesn't help that both of my Sunny Dayers are weak to Crunch, though Cress can take one without dying. If I can set up Breloom while TTar's not in it'll die, but this requires forcing TTar out. Easier said than done.
-CBTar: Has a tendency to get locked into something that doesn't kill Breloom or Cress.
-LO Tar: Ick. Ick ick ick. My best shot is to get a Sunny Day off with Cress and then Moonlight back to a reasonable amount of health, paralyze it, and switch to Heatran (no one's stupid enough to Earthquake on a Cress).
-DDTar: Slightly less ick because I get a free switch in on Cress.
-CurseTar: Cress outspeeds it to the point that I can come in on the switch, Sunny Day, and then Moonlight and not die.
-ScarfTar: See CBTar.
Latias:
-Specs: Cress or Drapion.
-Scarf: Cress or Drapion.
-LO Sweeper: Cress.
-CM Latias: Cress or Drapion.
Heatran:
-Lead Shuca/SashTran: Gets killed pretty fast by Shiftry/Exeggutor.
-ScarfTran: Depending on what it comes in on I can laugh at it. If it comes in on Heatran or Drapion I switch to Cress and Earth Power does jack. If he comes in Exeggutor I switch to my Heatran and he can't do anything. If he comes in on Cress he's about to get paralyzed. He won't ever have a reason to use a different move. The biggest problem is finding out what's a ScarfTran and what isn't.
-SpecsTran: Gets outsped by my Heatran, though again I have to find out if it *is* a Specstran.
-LO Tran: Best bet is to paralyze it with Cress and then get my Heatran in there.
-SubHeatran: See above.
Gyarados:
-Leftovers DD: Cress can wall, paralyze, and Sunny Day.
-Life Orb DD: same as above
-RestTalk: Drapion Taunts it.
-Thunder Wave or Substitute: Drapion can taunt it or a Cress/Exeggutor combo will do.
Metagross:
-Lead Gross: Shiftry+Exeggutor will kill.
-CBGross: Get Sunny Day up and let Exeggutor handle it, or use Breloom.
-MixGross: See CBGross
-Agiligross: See CBGross
Jirachi:
-Scarf Jirachi: Heatran laughs.
-Expert Belt Jirachi: See above
-CM Jirachi: See above
-Support Jirachi: See above
Infernape:
-MixApe: Hates being paralyzed and can't do much to Cress.
-Physical Ape: See above.
-ScarfApe: See above.
Lucario:
-SD: Exeggutor or Heatran.
-Specs: Same as SD
Gengar:
-LO Gengar: Drapion will OHKO if it gets a shot. Getting a shot can be hard. Gengar is a problem because it also walls Breloom. And kills Cress and Exeggutor. If it doesn't come in on Shiftry or kill something a combo of paralyzing with Cress and finishing with Heatran is my only hope
-ScarfGengar: Gets locked into Shadow Ball and then Drapion will OHKO.
-SubGengar: Drapion will Taunt and then OHKO.
Swampert:
-Standard Mixpert: My entire team laughs.
-CBPert: Still laughing
-Cursepert: Still laughing
-lead: Still laughing. Pert's not a problem
Starmie:
-LO Starmie: Heatran or Exeggutor.
-Rapid Spinner: Heatran or Exeggutor.
-Choice Starmie: Probably Heatran because it's unlikely to Surf
Blissey:
-WishBliss: AHAHAHAHAHAHAHAHA Drapion kills it OR Heatran kills it OR it can't do anything to Cress OR Shiftry explodes OR Breloom sets up
-Non-wish Bliss: Even funnier
Azelf:
-Lead Azelf: Owned.
-NP Azelf: I hate U-turn, but other than that I can paralyze or Drapion
-Scarf Azelf: Gets locked into something less than ideal for it.
Gliscor:
-SD Gliscor: Drapion hurts it bad, so does Solarbeam
-Stall Gliscor: See above. Also can't do jack to Breloom even if it does Taunt assuming it has no Aerial Ace
-BP Gliscor: Drapion
Magnezone:
-Substitute: Problematic. Heatran can usually kill it though
-Scarf: More problematic, except I can paralyze it if Cress is still around.
Skarmory:
-Spiker: Taunt it and render it useless, then switch in Heatran. In theory. In practice, Skarm is the biggest problem for my team.
Machamp:
-RestTalk: Exeggutor's Psychic.
-Substitute: Exeggutor.
-Anti-lead: Explode.
Vaporeon:
-WishProtect Vaporeon: Taunt, then Drapion or Eggsy for the Grass type move
-SpecsVaporeon: Never seen one I haven't used. Same as above
Breloom:
-SubPuncher: Taunt and watch it curse
-ScarfLoom: My team laughs
Dragonite:
-Lead: Sunny Day and Boom.
-DDNite: Cress, the answer to all dragons
-MixNite: See above
Zapdos:
-Defensive: Taunt+Ice Fang or Metal Sound, walled by Cress
-Offensive: Paralyzed and walled by Cress
-Choiced: Depends on what it uses
Flygon:
-Band/Scarf: Cress comes in on the inevitable EQ
-Roost LO/Stall: Taunt+Ice Fang
Kingdra:
-DD Kingdra: Lol paralyze
-Rain Dance Mix: Only saw it once but Cress handled it
Suicune:
-Offensive CMer: Metal Sound and Solarbeam.
-RestTalk: never seen one but theoretically it's setup fodder for Breloom
-Roar: Taunt
Celebi:
-Defensive: Lol
-CM / CM Pass: Lol
-SD Pass: Lol
-Choice: Lol
Jolteon:
-Specs: Heatran
-Substitute: Heatran
-Charge Beam: Heatran
Empoleon:
-Lead: Wounded by the kaboom and killed by Heatran
-AgilityPetaya: Taunt xD
-AgilityLife Orb: Heatran
-Specs: Gets locked into something that can't kill Cress
-SD: Cress probs.
Forretress:
-Spinner: Laugh maniacally
Bronzong:
-Standard Leftovers / Light Clay: Heatran.
-CMZong: Never seen it. Heatran tho :P
-Trick: Go to Exeggutor probably
Togekiss:
-Flinch Kiss: Drapion outspeeds it, taunts it, toxics it, then Ice Fangs
-Scarf Trick: Annoying but equally dead once it incapacitates something
Electivire:
-Physical LO: Walled by Cress
-MixVire: Same
Snorlax:
-CB: Breloom pretty much yeah.
-Curselax: Breloom pretty much yeah.
Aerodactyl:
-Lead: If they Taunt I don't get Sunny Day up but they don't get anything up either.
-LO Sweeper: Cress' Ice beam.
Weavile:
-Lead: Run like hell and get it paralyzed
-CB: Heatran
-SD: Paralyze and then Heatran
Tentacruel:
-Toxic Spiker: Drapion absorbs toxic spikes, everything else kills it
Dusknoir:
-Standard Wall: Drapion is my de facto Ghost Killer. Alternately, I can Taunt, switch to Heatran, and toast it.
Mamoswine:
-Lead: Ice Shard is priority so I must explode first.
-LO: Get Sunny Day up with Cress and going to Exeggutor on the EQ is kinda my only option >.> Alternately Drapion can toxic the guy.
-CB: Trick it into EQing and switch to Cress or trick it into Ice Sharding and go to Heatran
Roserade:
-Lead: Absorb the sleep and Switch in with Heatran. (I'm meant to die anyways >.>).
-Non-Lead Spiker: Drapion or Heatran. Cress can prolly wall it
-LO Sweeper: same as above
Smeargle:
-Lead: Fake Out, Boom
-Belly Drum Pass: kill whatever comes in :P
Hippowdon:
-Wall: Don't make me laugh
Ninjask:
-Lead passer: Switch to Drapion, Taunt, laugh
Heracross:
-CB: Shouldn't have much luck against Drapion, though I haven't run into one yet
-SD: same as above
Porygon-Z:
-Scarf: Just blow it to hell, probably with Heatran
-Nasty Plot: See above
Cresselia:
-Wall: Drapion
-Dual: same as above
-Trick: same as above
-Calm Mind: same as above
Umbreon:
-Standard wall: Metal Sound it with Heatran and kill, or Explode if its switches in on the lead, or if I'm lucky Breloom (though I haven't tried that)
-Mean Look Yawn BPer: Ugh.
Main strengths:
1. Damn near impossible to wall
2. Defeats any and all stall teams
3. Rips through most of the most common OU threats, i.e. Scizor, Metagross, Salamence, Swampert
4. Once TTar is out of the equation it slaughters sandstorm teams, even if Sandstorm is still up due to Hippowdon
So far, my team's weaknesses (specific and nonspecific) are:
1. Skarmory
2. Ghost-types in general, but particularly Gengar
3. Togekiss
4. No Rapid Spinner to deal with Rocks/Spikes or anyone to set them up
Translation: Drapion's not really doing its job
Well, RMT #1 for me on Smogon. Yay, I guess. My previous two teams were decent, netting me 40-65% win chances, but had enough problems that I didn't bother taking them to here: this one, I think, is better. I hope.
Anyways, I was reading through the Smogon site trying to improve a Trick Room team and I somehow wound up on the page for Pokemon that learned Fake Out. I also happened to be on the page for Explosion at the time... and it hit me. Shiftry: The only Pokemon in the game to get Fake Out and Explosion, with enough stats to do some serious damage with the latter. Focus Sash leads, I saw, would quail before its might. The only problem was the Speed.
Luckily, it had Chlorophyll, and this Sunny Day team was born.
At a glance:






The Lead: Shiftry @ Focus Sash
EVs: 4 HP 252 Atk 252 Spe
Ability: Chlorophyll
Nature: Hasty
Fake Out
Sunny Day
Explosion
Faint Attack
So yeah. Maybe this idea is flawed, but it seems to work pretty damn well in matches. Fake Out on turn one, Sunny Day on turn two, Explode the same turn your HP drops below 100% and Faint Attack until then. Faint Attack is there for those pesky Ghost-types who like to eat Explosions. If I see a lead that I know is probably carrying priority (e.g. Scizor, Machamp) I can forgo the Sunny Day and just explode, or switch out. EVs are obviously there to make the big kaboom hurt more. This would be incredibly epic in UU and I have no idea why no one's thought of it (and posted it) yet, but it still works decently in OU.
How it stacks up against other leads:
Azelf: Is dead. 100% chance. Unless, of course, he U-Turns to something else, in which case whatever he U-Turned to is dead. Sunny Day is up.
Aerodactyl: If he Taunts me he gets Stealth Rock up and I don't get Sunny Day up. Then he dies. If he decides to SR first instead of Taunting because he thinks I attack Sunny day **is** up.
Swampert: Exploding works like a charm. He can't Roar me out because if he does my entire team laughs in his face once Sunny Day is up. Which it will be if he Roars. Or does anything, really.
Metagross: Explosion might not kill it but Exeggutor sure as hell will the next turn. Sunny Day is up.
Jirachi: Abuse Faint Attack after a Sunny Day. If he kills me, I always have Exeggutor. If I get him below 60%, meaning two of Faint Attacks, an Explosion will guaranteeably finish him.
Infernape: Run like hell and switch to Cress.
Machamp: Machamp tends to carry Bullet Punch, forcing me to explode before I can Sunny Day. Good news is that he doesn't get to set anything up either.
Ninjask: Spam Faint Attack or switch to Drapion and watch him scream as I taunt him.
Roserade: Um... hope that the sleep misses. If it doesn't, it's just as though I exploded on a Ghost-type. Heatran can handle this guy.
Tyranitar: It's unfortunate that Sandstorm breaks my Sash. Then again, explosion puts a huge dent in this guy.
Scizor: Sunny Day, Explode, finish it with Exeggutor which is now set up.
Abomasnow: So Ice Shard means I can't put up Sunny Day right away. His hail inducer is dead. Who do you think won?

Special Sweeper: Heatran @ Life Orb
EVs: 4 Def 252 Spe 252 SpA
Ability: Flash Fire
Nature: Modest
Solarbeam
Substitute
Earth Power
Fire Blast
Substitute Heatran is a good idea, and hilariously enough it's my Heatran counter. Heatran coming in on my team inevitably wants to use either Fire Blast or Earth Power, which means either switch to Cress (if Heatran or Drapion is in) or Heatran (if Exeggutor or non-set-up Breloom is in). After I switch to Heatran, I immediately switch to Cress to avoid the obvious Earth Power. If it's a non-Scarf, it'll stay in despite the miss and Fire Blast, letting me T-Wave it. No Heatran is retarded enough to Earth Power Cress, meaning that I can heal up with Moonlight and switch back to Heatran for my Earth Power kill. Choice Scarf Heatran obviously runs like hell the instant I absorb their Fire Blast, and I get to paralyze whatever they bring in with Cress. If they have a Substitute Heatran and call that I'm going to run... my best option is trying to win a speed tie, which is less than ideal. Solarbeam is always a surprise for Swamperts who come in thinking they can wall Fire Blast and Earthquake me. Heatran always nets me at least 1 kill and usually 2-3. It's usually kept in reserve until Exeggutor is wounded because Eggy is the preferred switch-in after my Shiftry dies in order to let me abuse Chloropyhll. Fire Blast is there for STAB, though its inaccuracy displeases me. It absolutely slaughters Forretress and Scizor (once Cress has worked its magic). Metagross hates Fire Blast unless it carries Occa Berry, in which case it hates Earth Power. Fire Blast is also a pretty effective means of taking out Skarm, though few Skarms are stupid enough to switch in on Heatran unless they expect to absorb a probable Earth Power. Which is there for coverage. EVs are obvious.

Wall: Cresselia @ Heat Rock
EVs: 252 HP 252 Def 4 SpD
Ability: Levitate
Nature: Bold
Thunder Wave
Ice Beam
Moonlight
Sunny Day
I love Cress. It should be OU and no longer banned to that horrid land known as BL. At any rate, it makes things interesting for other teams. Fast sweepers such as Infernape and Gengar get paralyzed, which ruins their whole day. Not to mention that Sunny Day + Moonlight gives me reliable 66.7% healing. It also rips through Mences like nobody's business. They can't do jack to it and next turn they eat an Ice Beam to the face. Dragonite hates it almost as much. This is the number one reason why none of my opponents have ever gotten a single KO with Mence. CB Scizor also hates being paralyzed, though I have to watch out for Bug Bite. Gengar is trouble, but it too hates being paralyzed and can't OHKO. Togekiss is a pain in the ass but I can parahax it back.

Setup Sweeper: Exeggutor @ Life Orb
EVs: 4 Def 252 Spe 252 SpD
Ability: Chlorophyll
Nature: Modest
Grass Knot
Hidden Power Fire
Psychic
Sunny Day
Usually my switch after the lead, unless the lead was Abomasnow in which case I rather expect their team to be completely capable of killing Exeggutor. Chlorophyll is hilariously awesome. STAB Psychic rips through Infernape if Sunny Day is up (making me faster than it). Grass Knot 2HKOes TTar, though the odds that I get off 2 Grass Knots is unfortunately low due to Crunch. ScarfTar hates this set, though, if it's locked into something not named Crunch. Pert hates me. In fact, all bulky waters get 2HKOed here, though I prefer Heatran for taking them out. This guy's Sunny Day seems to last forever. Scizor and Metagross die rather horribly to HP Fire. Skarm gets killed too if Cress has already paralyzed it. Hippowdon is an OHKO to Grass Knot. EVs were obvious.

Wallbreaker: Drapion @ Leftovers
EVs: 252 HP 92 Atk 56 Def 108 Spe
Ability: Battle Armor
Nature: Impish
Crunch
Toxic
Ice Fang
Taunt
Liking this set reasonably well so far. Basically I noticed that my team was having some trouble with Gengar, Skarm, and Togekiss. Drapion ruins a phazing Skarm by Taunting it and then switching to Heatran. Unfortunately, the Skarm just runs away and I have to do it all again. Crunch is EV'd to guarantee a OHKO on Gengar, which works if Gengar doesn't sub. Ice Fang, Toxic, and Taunt in tandem absolutely slaughter Togekiss, which will always be outsped, assuming it's dumb enough to stay in (read: not too often). I went for Toxic over Toxic Spikes because Toxic Spikes statuses incoming counters to Breloom, which means it can't Spore them. This guy is actually a rather superb wallbreaker when it comes to things like Bliss, Clefable, and Cress, but it really can't do jack to Skarm.

Counter: Breloom @ Toxic Orb
EVs: 236 HP 248 Def 24 Spe
Ability: Poison Heal
Nature: Impish
Substitute
Leech Seed
Spore
Focus Punch
Standard SubSeeder. Damn, this thing is handy. Usually I keep it in reserve until everything else has scouted their team or I'm getting swept, which is admittedly rather rare. My team is pretty good at drawing out its counters, with the exception of Skarm (which is what Drapion is for). Breloom is good at sweeping the entire back half of most teams. Mence is never a problem. Breloom has really nice synergy with Drapion, each quite easily handling most of its counters.
Threat List stolen from someone else who probably also stole it from someone else so whatever:
Scizor:
-SD Variant: If I can get Sunny Day up, just go straight to Exeggutor and HP Fire for an OHKO. Otherwise paralyze it with Cress first and go to Heatran. Breloom also laughs at it.
-CB Variant: Same as above.
Salamence:
-MixMence: Cress.
-DD Bulky Mence: Cress.
-SpecsMence: Cress.
-CBMence: I'll give you one guess.
Rotom-A:
-Scarf: If it's caught on Overheat Heatran will stop it nicely. Otherwise Cress can paralyze it and then Heatran will stop it nicely.
-RestTalk: Breloom setup fodder.
-SubCharge Beam: Also hates being paralyzed and Metal Sound Heatran.
Tyranitar:
Just gonna get this out there; TTar is a problem because it takes out Sunny Day, which is nice to have around. It doesn't help that both of my Sunny Dayers are weak to Crunch, though Cress can take one without dying. If I can set up Breloom while TTar's not in it'll die, but this requires forcing TTar out. Easier said than done.
-CBTar: Has a tendency to get locked into something that doesn't kill Breloom or Cress.
-LO Tar: Ick. Ick ick ick. My best shot is to get a Sunny Day off with Cress and then Moonlight back to a reasonable amount of health, paralyze it, and switch to Heatran (no one's stupid enough to Earthquake on a Cress).
-DDTar: Slightly less ick because I get a free switch in on Cress.
-CurseTar: Cress outspeeds it to the point that I can come in on the switch, Sunny Day, and then Moonlight and not die.
-ScarfTar: See CBTar.
Latias:
-Specs: Cress or Drapion.
-Scarf: Cress or Drapion.
-LO Sweeper: Cress.
-CM Latias: Cress or Drapion.
Heatran:
-Lead Shuca/SashTran: Gets killed pretty fast by Shiftry/Exeggutor.
-ScarfTran: Depending on what it comes in on I can laugh at it. If it comes in on Heatran or Drapion I switch to Cress and Earth Power does jack. If he comes in Exeggutor I switch to my Heatran and he can't do anything. If he comes in on Cress he's about to get paralyzed. He won't ever have a reason to use a different move. The biggest problem is finding out what's a ScarfTran and what isn't.
-SpecsTran: Gets outsped by my Heatran, though again I have to find out if it *is* a Specstran.
-LO Tran: Best bet is to paralyze it with Cress and then get my Heatran in there.
-SubHeatran: See above.
Gyarados:
-Leftovers DD: Cress can wall, paralyze, and Sunny Day.
-Life Orb DD: same as above
-RestTalk: Drapion Taunts it.
-Thunder Wave or Substitute: Drapion can taunt it or a Cress/Exeggutor combo will do.
Metagross:
-Lead Gross: Shiftry+Exeggutor will kill.
-CBGross: Get Sunny Day up and let Exeggutor handle it, or use Breloom.
-MixGross: See CBGross
-Agiligross: See CBGross
Jirachi:
-Scarf Jirachi: Heatran laughs.
-Expert Belt Jirachi: See above
-CM Jirachi: See above
-Support Jirachi: See above
Infernape:
-MixApe: Hates being paralyzed and can't do much to Cress.
-Physical Ape: See above.
-ScarfApe: See above.
Lucario:
-SD: Exeggutor or Heatran.
-Specs: Same as SD
Gengar:
-LO Gengar: Drapion will OHKO if it gets a shot. Getting a shot can be hard. Gengar is a problem because it also walls Breloom. And kills Cress and Exeggutor. If it doesn't come in on Shiftry or kill something a combo of paralyzing with Cress and finishing with Heatran is my only hope
-ScarfGengar: Gets locked into Shadow Ball and then Drapion will OHKO.
-SubGengar: Drapion will Taunt and then OHKO.
Swampert:
-Standard Mixpert: My entire team laughs.
-CBPert: Still laughing
-Cursepert: Still laughing
-lead: Still laughing. Pert's not a problem
Starmie:
-LO Starmie: Heatran or Exeggutor.
-Rapid Spinner: Heatran or Exeggutor.
-Choice Starmie: Probably Heatran because it's unlikely to Surf
Blissey:
-WishBliss: AHAHAHAHAHAHAHAHA Drapion kills it OR Heatran kills it OR it can't do anything to Cress OR Shiftry explodes OR Breloom sets up
-Non-wish Bliss: Even funnier
Azelf:
-Lead Azelf: Owned.
-NP Azelf: I hate U-turn, but other than that I can paralyze or Drapion
-Scarf Azelf: Gets locked into something less than ideal for it.
Gliscor:
-SD Gliscor: Drapion hurts it bad, so does Solarbeam
-Stall Gliscor: See above. Also can't do jack to Breloom even if it does Taunt assuming it has no Aerial Ace
-BP Gliscor: Drapion
Magnezone:
-Substitute: Problematic. Heatran can usually kill it though
-Scarf: More problematic, except I can paralyze it if Cress is still around.
Skarmory:
-Spiker: Taunt it and render it useless, then switch in Heatran. In theory. In practice, Skarm is the biggest problem for my team.
Machamp:
-RestTalk: Exeggutor's Psychic.
-Substitute: Exeggutor.
-Anti-lead: Explode.
Vaporeon:
-WishProtect Vaporeon: Taunt, then Drapion or Eggsy for the Grass type move

Dragonite:
-Lead: Sunny Day and Boom.
-DDNite: Cress, the answer to all dragons
-MixNite: See above
Zapdos:
-Defensive: Taunt+Ice Fang or Metal Sound, walled by Cress
-Offensive: Paralyzed and walled by Cress
-Choiced: Depends on what it uses
Flygon:
-Band/Scarf: Cress comes in on the inevitable EQ
-Roost LO/Stall: Taunt+Ice Fang
Kingdra:
-DD Kingdra: Lol paralyze
-Rain Dance Mix: Only saw it once but Cress handled it
Suicune:
-Offensive CMer: Metal Sound and Solarbeam.

-AgilityLife Orb: Heatran
-Specs: Gets locked into something that can't kill Cress
-SD: Cress probs.
Forretress:
-Spinner: Laugh maniacally
Bronzong:
-Standard Leftovers / Light Clay: Heatran.
-CMZong: Never seen it. Heatran tho :P
-Trick: Go to Exeggutor probably
Togekiss:
-Flinch Kiss: Drapion outspeeds it, taunts it, toxics it, then Ice Fangs
-Scarf Trick: Annoying but equally dead once it incapacitates something
Electivire:
-Physical LO: Walled by Cress
-MixVire: Same
Snorlax:
-CB: Breloom pretty much yeah.
-Curselax: Breloom pretty much yeah.
Aerodactyl:

-LO Sweeper: Cress' Ice beam.
Weavile:
-Lead: Run like hell and get it paralyzed
-CB: Heatran
-SD: Paralyze and then Heatran
Tentacruel:
-Toxic Spiker: Drapion absorbs toxic spikes, everything else kills it
Dusknoir:
-Standard Wall: Drapion is my de facto Ghost Killer. Alternately, I can Taunt, switch to Heatran, and toast it.
Mamoswine:
-Lead: Ice Shard is priority so I must explode first.
-LO: Get Sunny Day up with Cress and going to Exeggutor on the EQ is kinda my only option >.> Alternately Drapion can toxic the guy.
-CB: Trick it into EQing and switch to Cress or trick it into Ice Sharding and go to Heatran
Roserade:
-Lead: Absorb the sleep and Switch in with Heatran. (I'm meant to die anyways >.>).
-Non-Lead Spiker: Drapion or Heatran. Cress can prolly wall it
-LO Sweeper: same as above
Smeargle:
-Lead: Fake Out, Boom
-Belly Drum Pass: kill whatever comes in :P
Hippowdon:
-Wall: Don't make me laugh
Ninjask:
-Lead passer: Switch to Drapion, Taunt, laugh
Heracross:
-CB: Shouldn't have much luck against Drapion, though I haven't run into one yet
-SD: same as above
Porygon-Z:
-Scarf: Just blow it to hell, probably with Heatran
-Nasty Plot: See above
Cresselia:
-Wall: Drapion
-Dual: same as above
-Trick: same as above
-Calm Mind: same as above
Umbreon:
-Standard wall: Metal Sound it with Heatran and kill, or Explode if its switches in on the lead, or if I'm lucky Breloom (though I haven't tried that)
-Mean Look Yawn BPer: Ugh.
Main strengths:
1. Damn near impossible to wall
2. Defeats any and all stall teams
3. Rips through most of the most common OU threats, i.e. Scizor, Metagross, Salamence, Swampert
4. Once TTar is out of the equation it slaughters sandstorm teams, even if Sandstorm is still up due to Hippowdon
So far, my team's weaknesses (specific and nonspecific) are:
1. Skarmory
2. Ghost-types in general, but particularly Gengar
3. Togekiss
4. No Rapid Spinner to deal with Rocks/Spikes or anyone to set them up
Translation: Drapion's not really doing its job
