Koga's Arbok (gym2_ja-19) is a Stage 1 Grass-type Pokémon from the 闇からの挑戦 expansion. Its first attack Poison Buildup poisons itself, and its second attack Poison Power deals higher damage and poisons the opponent if this Pokémon is already poisoned. The card carries a Psychic weakness and a Colorless retreat cost, shaping its matchup and mobility considerations in play.
