Koga's Ninja Gym

This card stays in play after being played. Discard this card if another Stadium card comes into play. Once during each player's turn (before attacking), that player may flip a coin. If heads, that player searches his or her deck for a Basic Pokémon with Koga in its name. Then, that player puts that card on his or her Bench. (A player can't do this if his or her Bench is full.) That player shuffles his or her deck afterwards. (CoroCoro 1999)
