Well I'm new to competitive battles (seriously I've had like 10 at most) and I've made my first ever team. I knew I wanted Trick Room as my "theme" straight away as turning an opponents advantage (speed) on it's head is something I love. Anyway I'm not really sure of the current threats AT ALL so feel free to change any Pokémon and lecture me :) I need it. Also I'm not really good with planning EV's so I just done 252 or 126/126 spreads :S
I play with Item Clause on.
BOLD = CHANGES MADE
Exeggutor @ Focus Sash - Quiet
Ability: Doesn't matter here.
EV: 252Atk/252SpA/4HP
-Explosion
-Trick Room
-Leaf Storm
-Psychic
Exeggutor almost always guarantees Trick Room is set up on the first turn. With Hariyama out on the field flinching the other Pokémon, Focus Sash cannot be nullified (unless they've got two Ghosts). By "nullified" I mean I can't get OHKOED but I do realise it will get activated and then I can die by weather conditions. If Exeggutor can take another hit after TR is up I'll do some damage then Explode.
Hariyama @ Muscle Band - Brave
Ability: Thick Fat
EV: 252Atk/126Def/126SpD
-Protect
-Fake Out
-Close Combat
-Stone Edge
Hariyama ALWAYS goes out with Exeggutor because it has Fake Out which ensures TR is set up. HP is already huge and the Def/SpD EV's ensure he can take a hit or two from the first round and still be there to do damage once TR is up. CC gets STAB and Stone Edge was more of a powerful filler as I don't have access to Emerald/Platinum (yet) for Ice Punch. Protect is to make sure Hariyama isn't taken out by Exeggutor's Explosion. Thick Fat as an ability helps to make up for the Fire weakness on my Parasect but I don't think that matters if Parasect is out AFTER Hariyama.
Parasect @ Bug Plate - Brave
EV: 252Atk/126Def/126SpD
Ability: Dry Skin
-Spore
-Seed Bomb
-Swords Dance
-X-Scissor
I've found Parasect to be INCREDIBLY useful to me. Depending on what Pokémon's out I either Spore or just go and SD straight away. Spore normally forces switches and Seed Bomb gives me a little coverage. I did use Stun Spore but it would turn out to be counter-productive in the long run (thanks again Starman). I know I only having 1 attack (and it being bug as well) is bad but after a SD or two it's still going to hurt. After TR as well Parasect is the "fastest" on my team.
Dusclops @ Leftover - Relaxed
Ability: Pressure
EV: 252HP/252Def OR SpD/4Atk
-Trick Room
-Pain Split
-Shadowpunch
-Protect
I'm not sure whether or not to pump max EV's into either Def or Special Def (SpD) on Dusclops. I could split them like I've done on my other Pokémon though. Any suggestions here anyone? Anyway, Trick Room is here because I need another Roomer and Pain Split offers recovery and slight damage (well not really damage) to the opponent. S.Punch over Sneak as I'm not going to need priority really under TR conditions and Punch has more power. Any suggestions on what I could put on the last slot other than Protect? I would use Thunderpunch or something similar but (as I've already said) I don't have access to Emerald/Platinum yet. I'm only using Protect for now as it gives me immunity (for one turn) to Rampardos' EQ.
I chose to use Dusclops over Slowking for several reasons. The first being that I wanted a Slowking to set up, Slack Off damage and then sweep as well as being able to TR. Too many jobs for one Pokémon. Plus setting up doesn't really work under TR conditions as most TR sweepers are very fragile. Dusclops also offered an invaluable Explosion immunity which if I wanted on Slowking meant I needed to run Protect somewhere.
Rampardos @ Life Orb/Choice Band - Brave
EV: 252HP/252Atk/4Def
Ability: Mold Breaker
-Head Smash
-Zen Headbutt
-Earthquake
-Rock Slide
Rampardos isn't meant to be around for long so I thought heck, may as well let him go out with a bang so I gave him Life Orb. Head Smash tears through most things and Zen Headbutt gives coverage as does EQ. Stone Edge is a filler over Fire Punch because (as already mentioned), I don't have Emerald/Platinum. Rock Slide (thanks StarmanXL) hits both of my opponents Pokémon and with Rampardos' attack it won't make much of a difference in terms of power. Plus I get a chance to flinch both Pokémon.
Choice Band gives more of a boost than Life Orb but locks me into one move which is almost always bad for me. Life Orb doesn't restrict me at all but, (as pointed out by Relictivity), Head Smash + Life Orb = Dead in 2 turns.
Camerupt @ ??? - Brave/Quiet
Ability: Solid Rock
EV: 252SpA/156Atk/96HP
-Eruption
-Earth Power
-Flamethrower/Heatwave
-Explosion
I know I should use more EV's in HP to give Eruption power but 156Atk EV's (I think) give me a OHKO on almost everything or it will at least bring Pokémon down to the red HP zone with Explosion. Eruption hits both Pokémon (opponents) right off the bat at max power (full HP) and I can switch to a (with lower HP) stronger Heatwave that still hits both Pokémon. Earth Power is like a single target EQ and Explosion lets him go out with a boom. I don't have to worry about Explosion anymore as Dusclops is a Ghost and is immune. Any suggestions for items though anyone? I'm not sure what to put on here because of Item Clause. I might just take it off.
That's my team so feel free to criticise and point out any flaws in my team (I know there will be a lot but please post some =]). I know that I don't have a Gyarados counteror really any other OU counter but I just can't think of any that fits into a TR team and I'm not too fussed about OU either (not that I know the current threats or anything lol). I'm not sure what other threats there are in OU so feel free to change this team as you see fit. Even change this team to single battles if you want because I don't mind playing singles but I just prefer doubles.
Please just take some time to RMT even if it is just pointing out basics to me :)
