Bloodthirsty Conqueror + Arcbond + Return the Favor

Bloodthirsty Conqueror

Arcbond

Return the Favor

How it works

1. Cast Arcbond by paying 2, targeting Bloodthirsty Conqueror.
2. Holding priority, cast Return the Favor by paying its mana cost, copying Arcbond, with the copy targeting another indestructible creature you control.
3. Resolve both Arcbonds.
4. Deal damage to Bloodthirsty Conqueror.
5. Arbond triggers, dealing that much damage to each player and each other creature.
6. Bloodthirsty Conqueror triggers for each opponent dealt damage, and Arcbond triggers due to the other indestructible creature being dealt damage.
7. Resolve all Bloodthirsty Conqueror triggers, causing you to gain life.
8. Resolve the Arcbond trigger, dealing that much damage to each player and each other creature.
9. Bloodthirsty Conqueror triggers for each opponent dealt damage, and Arcbond triggers due to Bloodthirsty Conqueror being dealt damage.
10. Resolve all Bloodthirsty Conqueror triggers, causing you to gain life.
11. Resolve the Arcbond trigger, dealing that much damage to each player and each other creature.
12. Repeat form step 6.

This explosive loop relies on a brilliant synergy where damage and life-gain endlessly feed into one another. By using Return the Favor to copy Arcbond, you duplicate the enchantment's fiery payload onto another indestructible creature alongside your Bloodthirsty Conqueror. Once any initial damage sparks the chain, Arcbond blasts every player and creature, which immediately triggers Bloodthirsty Conqueror to restore your life. That sudden loss of life and subsequent damage to your creatures continuously feeds the Arcbond triggers back into the loop, resulting in infinite damage and life.
