Rule 135.2.b.3

Instructions will self-describe when they are to be executed. If there is no timing described, they will execute during resolution. Example: An instruction says “as you play me, kill a unit as an additional cost.” That instruction will execute as the card is being played. If the card is given Repeat and the Repeat cost is paid, this instruction will not execute because the Repeat execution does not happen until resolution of the spell, after this instruction has executed.
