Crobat

Having four wings enables it to fly faster and more quietly. It turns active when the night comes.

Poke-POWER — Evolutionary Toxic: Once during your turn, when you play Crobat from your hand to evolve 1 of your Pokémon, you may choose 1 of the Defending Pokémon. That Pokémon is now Poisoned. Put 2 damage counters instead of 1 on that Pokémon between turns.

Strike and Fade: Choose 1 of your opponent's Pokémon. This attack does 50 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Flip a coin. If tails, shuffle Crobat and all cards attached to it back into your deck.
