Flip a coin. If heads and if any of your Pokémon have any damage counters on them, then remove 2 damage counters from 1 of them (or 1 if it only has 1). If tails and if any of your opponent's Pokémon have any damage counters on them, choose 1 of them and remove 2 damage counters from it (or 1 if it only has 1).

Flip 2 coins. This attack does 40 damage times the number of heads.
