Caterpie 63/106 - Great Encounters

Once during your turn (before your attack), if Caterpie is your Active Pokémon, you may flip a coin. If heads, search your deck for a card that evolves from Caterpie and put it onto Caterpie. (This counts as evolving Caterpie.) Shuffle your deck afterward. This power can't be used if Caterpie is affected by a Special Condition.
