Zoo is an aggressive multicolor archetype built around highly efficient creatures backed by burn and disruption. Its creatures often become stronger when the deck controls several basic land types, making fetch lands and dual lands central to classic builds.
Tarmogoyf and Tribal Flames have appeared in larger Zoo variants, while Steppe Lynx and Goblin Guide push faster versions toward pure aggression. Whatever the exact menagerie, Zoo wants more creatures for its mana than opponents can comfortably handle.
