GW Tokens is a midrange/aggressive deck used often during Scars block and Innistrad block standard. Tokens uses mana ramp, such as Birds of Paradise and Avacyn's Pilgrim, token-producing cards, such as Hero of Bladehold and Elspeth Tirel, and numerous pump effects, such as Mikaeus, the Lunarch, Gavony Township, and Overrun, to quickly overwhelm opponents.
Its win condition is simply making as many tokens as possible and pumping them with various cards.
