Choose 1 of your Basic Pokémon in play. If you have a Stage 2 card that evolves from that Pokémon in your hand, put that card on the Basic Pokémon. (This counts as evolving that Pokémon.) You can't use this card during your first turn or on a Basic Pokémon that was put into play this turn.
You may play as many Item cards as you like during your turn (before your attack).
