Once during your turn (before your attack), you may put Sudowoodo from your hand onto Bonsly (this counts as evolving Bonsly) and remove all damage counters from Bonsly.

Flip a coin. If heads, your opponent can't play any Trainer cards from his or her hand during your opponent's next turn, and any damage done to Bonsly by attacks is reduced by 30 (after applying Weakness and Resistance).
