Once during each player's turn, they may search their deck for a Stage 1 Pokémon that evolves from 1 of their Basic Pokémon in play and put it on that Pokémon to evolve it. If they do, they can then search for a Stage 2 Pokémon that evolves from that same Pokémon and evolve it. Then, that player shuffles their deck. (You can't use this effect if it's your first turn and you can't choose a Pokémon that was played this turn)
