Attach Star Piece to 1 of your PokÃ©mon that doesn't already have a PokÃ©mon Tool attached to it. If that PokÃ©mon is Knocked Out, discard this card.
At any time between turns, if the PokÃ©mon this card is attached to is Benched and has 2 or more damage counters on it, search your deck for an Evolution card that PokÃ©mon evolves into and put it on top of that PokÃ©mon. (This counts as evolving that PokÃ©mon.) Shuffle your deck afterward. Then, discard Star Piece.
