Azurill

Poke-POWER: Baby Evolution

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

Choose a basic Energy card in your hand and show it to your opponent. Then, search your deck for a Basic Pokémon or Evolution card of that Energy type, show it to your opponent, and put it into your hand. Shuffle your deck afterward.
