Koga's Arbok (printId gym2-25-Unlimited; 25/132) is a Grass-type Stage 1 Pokémon from the Gym Challenge expansion. Its Poison Buildup attack immediately poisons Arbok, and Poison Power deals higher damage and poisons the Defending Pokémon when Arbok is poisoned. The card supports poison-focused tactics but is weak to Psychic attacks and has a two Colorless retreat cost.
