Skull Skeepa, response to Dudebot: Blast Burn or such won't knock out the Pokemon on the first turn, and even then, when the opponent switches in, then it's toast if it's a good typing against yours.
Recoil damage doesn't matter. If it's supposed to be a sweeper, then as much damage as it can get in before it goes bye-bye the better... And resting moves don't help with that.
