Comeuppance — Mirror Strike of Karlov Manor

Comeuppance is a concise white instant that flips defensive scaffolding into an immediate offensive reply. Cast it when an opponent lines up lethal damage or when a planeswalker is under threat. It prevents all damage that would be dealt to you and planeswalkers you control this turn by sources you do not control and then redirects the prevented damage back at its origin, turning blocked attacks and directed spells into punishment of equal magnitude.

In Commander games where politics and attrition matter, this card punishes overcommitment and clears the board of problematic attackers or aggressive spellcasters. Use it to protect your life total while converting mass damage into removal or direct damage to an opponent. The wording is precise so it interacts cleanly with creature sourced damage and noncreature sources, making sequencing and stack decisions important the turn you play it.
