- 17 November 2017Creatures may be dealt damage greater than their toughness. For example, if a source deals 5 damage to Illusory Ambusher, you'll draw five cards.
- 17 November 2017If Illusory Ambusher blocks a creature with trample, that creature's controller can assign any amount of damage from 1 to that creature's power to Illusory Ambusher. Excess damage doesn't have to be assigned to the defending player.
