Slowbro FO 43

As often as you like during your turn (before your attack), you may move 1 damage counter from 1 of your Pokémon to Slowbro as long as you don't Knock Out Slowbro. This power can't be used if Slowbro is Asleep, Confused, or Paralyzed.

Flip a coin. If heads, the Defending Pokémon is now Paralyzed.
