Nidoqueen (MODSKR 22)
Once during your turn (before your attack), if Nidoqueen is on your Bench, you may search your deck for a card that evolves from your Active Pokémon and attach it to your Active Pokémon. (This counts as evolving that Pokémon.) Shuffle your deck afterward.
Flip 2 coins. This attack does 30 damage plus 20 more damage for each heads.
