Whimsicott overpowered???

anyone think that it is over powered due to its high base speed
Mischievous Heart ability (none damageing moves go first)
and cotten guard attack (increases defence by 3 tears)
so without evs it will have over 232 def
all you need are these 4 attacks
giga drain stab
flash
toxic
cotten guard
for evs maybe 252 def / 252 hp or sp attack
give it left overs
adament nature

ther you go about 300 def off of first turn
use flash once or twise then go and spam giga drain stab
it will own any physical sweeper on the 2nd turn you can have 340 def not including evs

Flash is considered Hax, and so is banned under certain clauses. So take flash out of that set. It could be considered to be overpowered, but what's it's sp. Atk Stat like? If it's somewhat low, then there are alot of walls like this. They are supposed to be very overpowered in Defenses, but low in Offenses. Then you can consider it's Sp. Def. Stat. It may not stand a chance against special sweepers.

^ Flash isn't banned and is frankly a terrible move lol.

That set loses to every and all steel types and also PHazers/Taunt users. Its also at risk from Toxic Spikes amongst other things. Its sp.att is too weak to use Giga Drain or any attacking moves.

Icicle Spear Cloyster and anything with multi hit moves beat it.

Magic Mirror Espeon and Xatu are 100% counters.

Regardless its not overpowered in the slightest, without Taunt or Encore its set up bait. It has many counters (even others i didnt mention) and is actually rather overated. The only thing its good for it stopping stat up sweepers with Taunt/Encore and sub seeding, though its even unreliable at that really as if it takes a hit on the way in it hasn't accomplished anything.
