Koga (19/132, Unlimited Holofoil) is a Rare Holo Trainer from the Gym Challenge expansion. If a Pokémon with Koga in its name deals damage to the Defending Pokémon this turn, that Defending Pokémon becomes Poisoned. Its battle-related effect is intended for use during matches, so it is legal for deck inclusion.
