Pokémon Power [Vanish]
When you play Unown [V] from your hand, you may flip a coin. If heads, return 1 of your Pokémon with Unown in its name (other than Unown [V]) to your hand. (Discard all cards attached to that card.)
You may have up to 4 Basic Pokémon cards in your deck with Unown in their names.
