Trample (This spell can deal excess damage to its target's controller.)
Super-Duper Death Ray deals 4 damage to target creature.
Trample on an instant or sorcery is similar to how it works on an attacking creature. If Super-Duper Death Ray would deal more damage that what it would take to destroy the creature (called â€œexcess damageâ€), it deals the excess to the creatureâ€™s controller. For example, if you aim Super-Duper Death Ray at a 1/1 creature, it will deal 1 damage to the creature and 3 damage to its controller.
Super-Duper Death Ray targets only the creature. It can deal damage to a player with hexproof, for example.
If Super-Duper Death Ray doesnâ€™t resolve because its target leaves the battlefield or otherwise becomes an illegal target in response, it will have no effect. It wonâ€™t deal damage to any creature or player.
If damage is already marked on the creature, that damage is considered when calculating excess damage. For example, say your opponent controls a 6/6 creature. Your first Super-Duper Death Ray deals 4 damage to it. Then your SECOND Super-Duper Death Ray (i.e. the one they never see coming) deals 2 damage to the creature and 2 damage to your opponent.
