Support Build Mimikyu
Mimikyu @Light Clay, Iapapa Berry
Play Rough/Shadow Claw/Leech Life
The idea is that the little guy leads. With the EV spread, both of his defences round up around the same area, which allows it to tank on either side, setting Light Screen for itself (and teammates) if it's against a special attacker, or beginning to bulk up if it's a physical attacker. Bulk Up also utilizes the little guy's decent attack. Play Rough is for STAB and also for if you fear more physical attackers. (As it has a chance to lower attack) Shadow Claw is for if you want raw damage and to abuse Bulk Up. Leech Life is for regen, if you wanna be more tanky.
Don't take Will-O-Wisp or Reflect if you take Play Rough, since you're already covering for pysical. (Unless you wanna be dual Screener.) Also, I thought Trick Room was a good move to further Mimikyu's support. If you take Shadow Claw, either three moves can work for last slot. Same goes for Leech Life, but I don't recommend Trick Room if you do take Leech Life.
Anyway, what do you guys think?
