Here's a team that's been treating me very well over the last week or so, bringing my testing alt up to 1600 CRE and generally rocking face. It still does have a couple weaknesses, but the biggest one is still me overpredicting :(. Without further adieu, the team:
The lead:
Ambipom@Life Orb
66 HP/252 Atk/192 Spe
Adamant/Technician
-Fake Out
-Return
-Pursuit
-Brick Break
Comments: Ambipom is the best lead out there with Crobat gone, except arguably Yanmega (that damn bug needs to go BL soon <_<). Technician boosted Fake Out with Adamant does ridiculous damage to most everything. Fake Out + 2 Returns = a dead defensive Donphan. Pursuit is even more amazing, the first of my trapping skills. It gets the technician boosts and capitalizes on taking out fast, fragile leads that flee from Fake Out. 66 HP EVs garuntee I'll be able to take a Modest Yanmega Bug Buzz while I Return and still switch into SR for another Fake Out or pursuit. Return puts him within KO range of most of my priority, but often times he'll still kill something because, well, he's Yanmega. People that switch to Mismagius or Rotom to avoid Fake Out are in for a nasty surprise as Pursuit 2HKOs the most defensive variants of the two, the former even after a Will-o-Wisp (which my entire team hates, I'd rather get rid of it and lose some utility on Ambipom than have it hit Honchkrow, for example.) even when they don't switch out. The only lead he's consistently lost to (besides aforementioned Yanmega) is Paraflinch Uxie, but that's ridiculously rare. Brick Break is there to break Dual Screen Uxie (who is everywhere) and to 3HKO Registeel in case Magneton is down.
IT'S A TRAP!
Magneton@Leftovers
4 HP/252 SpA/252 Spe
Magnet Pull/Modest
-Substitute
-Thunderbolt
-HP Ice
-Magnet Rise
Summary: The steel killer. This thing comfortably sets up on Registeel and Steelix while they can do nothing but Explode or Roar. HP Ice helps to nail ground types that switch into him as well as Roserade, who can barely dent Magneton barring a LO Leaf Storm without a drop. He can also setup on other walls like Regirock who can't do much to it (Stone Edge doesn't even break sub without decent attack investment, has low PP, and low accuracy) and threaten bulky waters like Milotic, although it will take a hefty chunk from Surf.
The Rain Dance Counter:
Toxicroak@Life Orb
4 HP/252 SpA/252 Spe
Timid/Dry Skin
-Nasty Plot
-Vacuum Wave
-Sludge Bomb
-Dark Pulse
Comments: Name says it all, he single handedly counters Rain Dance teams, being able to OHKO most of them while having the rain replenish the LO damage off of him. Not only that, but he can set up on and at least take down Milotic, even if he dies in the process, and that is very important as she pretty much walls or threatens the remainder of my team (Magneton can't switch into a Surf too often). If there's anything that's going to be sweeping, it's Toxicroak. At +2 he can OHKO most of the tier that's not specially defensive with the Neutral or SE move. Vacuum wave is the second of the priority attacks I have on this team (the first was Fake Out) and it takes care of most normals (2HKO's Blissey with Weight Loss at +4, Calm Chansey only at +6, but she should theoretically be weakened by that time). Sludge Bomb is the neutral STAB and Dark/Fighting is the perfect coverage.
Because Everyone Else Had One:
Milotic@Life Orb
252 SpA/202 Def/56 Spe
Marvel Scale/Bold
-Surf
-Ice Beam
-Recover
-Haze
Comments: Milotic is what allows me to beat Blaziken and Cursers. She's remarkably sturdy while sporting quite decent offense with max SpA and Life Orb, and has a reliable recovery move. Ice Beam has a good chance of OHKOing the #1 switch in to Milotic (Roserade) after SR (assuming I predict correctly) and 2HKOs Venusaur. EVs allow it to outspeed Mixkin and not be 2HKO'd by them, while OHKOing them easily with Surf. Haze prevents stuff like Curse Regirock, Curse Miltank, Bulk Up Hariyama, Bulk Up Hitmonchan, etc from completely sweeping me. Surf is the obvious STAB and does ridiculous neutral damage (for a wall) with the LO and SpA EVs, getting some unexpected 2HKOs that can throw my opponent off (CM Clefable for one if I nail it on the switch as well). Milotic also absorbs status in dire situations. She doesn't mind a burn too much as it activates Marvel Scale, but she does lose 22% per attack, which can be very, very bad in some situations. Doesn't mind Paralysis much either. Bottom line: Every offensive team needs a bit of bulk, Milotic is my first line of defense.
The Second Line of Defense:
Donphan@Leftovers
100 HP/156 Atk/252 Def
Adamant/Sturdy
-Ice Shard
-Earthquake
-Stealth Rock
-Assurance
Comments: I needed someone to take powerful fighters like Hitmonlee and Medicham after they swept my early incarnation of this team. I also needed something that could take Thunder Waves and electric attacks while still maintining some offensive skill. I've gone through Trickscarf Rotom to Nidoking to Nidoqueen finally to Donphan. I have been thinking about swapping some EVs from Def to Atk to make sure Ice Shard finishes off Yanmega better (it only does ~24% for now, which is usually enough after an Ambipom return on the lead version. Fuck specs tinted lens.) which is the entire reason Ice Shard is there, although it does pick off Swellows that I can safely switch into with my massive defense. It makes the 3rd priority attack on my team. EQ is STAB and, honestly, the only way I'm ever gonna take out Lanturn, that guy used to wall my team completely when I had Rotom, now not so much. SR is obvious, it turns some 2HKOs into OHKOs, 3HKOs into 2HKOs and Yanmega into dead. Assurance is there for 3 reasons:
1) Filler
2) Stone Edge has crap accuracy and Ice Shard hits fliers.
3) It nails levitating ghosts and can even OHKO on the switch.
Stallbreaker Mismagius poses a problem as none of my team really enjoy a burn, Assurance and Pursuit are the 2 lines of defense against it.
The Beast:
Honchkrow@Life Orb
4 HP/252 Atk/252 Spe
Insomnia/Adamant
-Sucker Punch
-Pursuit
-Superpower
-Drill Peck
Comments: Standard set is standard for a reason, this rips holes in teams. Sucker Punch is the 4th priority attack on this team because I'm paranoid as hell about Yanmega. It can clean up easily late game and when combined with pursuit, creates a deadly set of mind games for me and my opponent to play. Pursuit is argubly my best way of dealing with Chansey and other special walls. They usually Wish on the switch and Chansey takes ~45-50% if it swaps out. Once they get wise to pursuit, I can mix it up and Superpower them to death while they stay in predicting pursuit. Speaking of Superpower, it 2HKOs Registeel, which is a plus if Magneton is down, and hits rock sweepers like CB Rhydon harder than anything else I'm carrying. Drill Peck is my reliable STAB attack and answer to bulky grass types like Venusaur and support roserade. He can easily come in on a Sleep Powder, then either OHKO with Drill Peck or predict the switch and Pursuit for a hefty chunk (this is where my overprediction sometimes screws me.) All in all, STAB Sucker Punch cleans up the scarfers and late game sweepers that could finish off my team (glares at Specs Yanmega) and Pursuit finishes off the 3 trap team that I have oh so enjoyed running.
Rate away.
