toxicroak pokemon card EX 041 [XY Flashfire] [2D] Toxic Ripper (120) Your opponents Active Pokémon is now Poisoned Rare Pokemon Card Stage 1

One of the quirks of the Commander rules is that if a mana symbol appears in the casting cost or in the text box of a card, the color of that mana symbol contributes to the card's "color identity."
