Hmm, Whimsicott was really improved this gen. I like the little puffball, good too see it become more viable. If it can learn Moonblast, how about this?
Whimsicott Choice Specs
32 HP / 252 SpA / 224 Spe
Timid
Prankster
Switcheroo
Encore
U-turn
Moonblast
It's a surprisingly powerful attacker, and can Encore trap non-Extremespeed variants of Lucario, which, aside from Talonflame, is the fastest priority in OU. The above calcs are with a neutral SpA nature, so it can run Timid with enough Speed EVs for Jolly Mega Lucario.
This actually looks quite good, I wanna try it now, heh! Whimsicott's job was never to take hits, so the loss of bulk isn't that big a problem. The extra resistances help too.
