Well, I might as well post my ideas because why not?
Deoxys-Defense @ Leftovers
Ability: Pressure
EVs: 252 Spd / 252 HP / 4 SDef
Timid Nature
- Agility/Amnesia/Cosmic Power/Calm Mind/Nasty Plot/Meteor Mash*/Power-Up Puch/Whatever 3 boosting moves that could break a sweeper
-
Baton Pass
Pretty much just Baton Pass your awesome stat boosts to the sweeper of you choice and then...well...sweep, I guess.
*Edit: Who would use Meteor Mash over Power-Up Punch? I mean, neither is a very efficient way to boost your attack, but if you must, it would be the only way.
Mew @ Leftovers/Focus Sash/Weakness Policy
Ability: Synchronize
EVs: 252 Spd / 252 HP / 4 SDef
Timid Nature
- Transform
-
Imprison
- Protect/Psyshock/Taunt/Roar/Roost/2 moves that fill a gap in your team
Imprison/Transform: Because fuck you, because fuck everything.
Other moves are there and feel free to fill that up with whatever you want for they are obsolete imo.
I happen to like the idea of a Weakness Policy because there will always be that stray Shadow Ball Cofagrigus or whatnot trying to screw you over and you will automatically gain +2 Atk and +2 SpA from that. Then just roar that Cofagrigus out and you can pretty much transform into anything and still have more offensive potenital over your transform victim.
Greninja @ Life Orb/Choice Scarf/Choice Specs/Item that looks cool on Greninja
Ability: Protean
EVs: 252 Spd / 252 SAtk / 4 HP
Timid Nature
- Three of you moves from your standard Greninja set
-
Nasty Plot
Mwahaha... haha. MWAHAHAHA!
MWHAHAHAHAHAHA!!!! HAHAHAHA!!! HA!! HA!!!! HA!!!!
Dusclops @ Eviolite
Ability: Pressure/Frisk. Why Should it matter?
EVs: 252 SDef / 252 HP / 4 SAtk
Calm Nature
-
Recover
- Taunt
- Infestation
- Will-O-Wisp
With Recover, Dusclops now adds a scary weapon to his stall arsenal. Step 1: Taunt. Step 2: Trap with Infestation. Step 3: Add on to Infestation's residual damage with Will-O-Wisp. Step 4: Recover. Repeat.
This set may look wimpy, but I have used a similar set in OU to take down the likes of Skarmory, Scizor, and Blissey. More than once.
That's all for now. If I think of any more set's I'll be sure to make your butts itch with more long-ass posts that you all don't feel like reading but read anyway because you have nothing better to do.
