When Tyrranax Cannon becomes tapped, it deals 1 damage to all creatures your opponents control.
Tap an untapped Telescoping Homunuculus, an untapped Throne of Command and an untapped Tyrranax Cannon: Deal 10 damage to target player. Activate this ability only any time you could cast a sorcery.
For Challenge # 028.
Are you meant to be the controller of all things? Also, is the card Throne of Command or Seat of Command?
