The Poison Mist Deck (Japanese: ポイズンミストデッキ) is a Theme Deck from Pokémon Card GB2: Here Comes Team GR! for the Game Boy Color. It predominately focuses on Pokémon and puts a strong emphasis on inflicting Poison for a status effect. This deck is one of many that cannot be made in either of the two Auto Deck Machines in Dr. Mason's Lab. The only person who plays with this deck is Rui, one of two bodyguards of King Biruritchi in the GR Castle, when the Tough Escape rule is in effect.
