One ruling from Wizards of the Coast
- 27 January 2026Use the creature's power as Madame Null's last ability resolves to determine how much life you may pay. If that creature is no longer on the battlefield, use its power as it last existed on the battlefield. (You probably won't want to pay life in that case, though.)
