×2Selective Slime
Once during your turn, you may flip a coin. If heads, choose Burned, Confused, or Poisoned. Your opponent's Active Pokémon is now affected by that Special Condition.
Miasma WindThis attack does 100 damage for each Special Condition affecting your opponent's Active Pokémon.
It has short legs and can’t walk very fast, but its neck and tentacles can extend to over three times their usual length to nab distant prey.
Can I use Cradily's "Selective Slime" Ability if my opponent's Active Pokemon is already Burned, Confused, and Poisoned?
No, you cannot. The only exception is if one of those is an "enhanced" Special Condition, such as Poisoned that places 2 damage counters instead of 1 during Pokemon Checkup.
