Ood Sphere

Card text

Song of the Ood — Noncreature spells have convoke. (A player's creatures can help cast those spells. Each creature they tap while casting a noncreature spell pays for {1} or one mana of that creature's color.)

Red-Eye — Whenever chaos ensues, for each opponent, goad up to one target creature that opponent controls. Until your next turn, those creatures can't become tapped unless they're being declared as attackers.
