Exile: Nantuko Shaman (3/2; Insect Shaman; When ~ enters the battlefield, if you control no tapped lands, draw a card. Suspend 1 -- 2GG (Rather than cast this card from your hand, you may pay 2GG and exile it with a time counter on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.))
