- 4 October 2004The payments are made when the spell resolves. The three options are: pay {2} to let creature act as normal, pay {1} to have creature neither deal or receive damage, or pay nothing and the creature does deal and receive damage but it will be destroyed at end of combat.
- 20 September 2013If a turn has multiple combat phases, this spell can be cast during any of them as long as it’s before the beginning of that phase’s Declare Blockers Step.
