Guilty Conscience + Boros Reckoner

Guilty Conscience

Boros Reckoner

How it works

1. Cause Boros Reckoner to take damage by any method.
2. Boros Reckoner triggers, dealing damage to an opponent.
3. Guilty Conscience triggers, dealing damage to Boros Reckoner.
4. Repeat from step 2.

This elegant two-card loop turns Boros Reckoner's own resilience against your opponents, letting a single initial spark cascade into an endless loop of damage. By enchanting Boros Reckoner with Guilty Conscience, you create a self-sustaining cycle: whenever Boros Reckoner is dealt damage, its triggered ability lets it strike any target—including itself—which in turn triggers Guilty Conscience to deal that exact same amount of damage right back to Boros Reckoner. Because this damage feedback loop never stops on its own, it easily clears a table of opponents or targets down any threat in formats like Commander, Legacy, Oathbreaker, and Vintage.
