Bloodthirsty Conqueror + Arcbond + Flare of Duplication

Bloodthirsty Conqueror

Arcbond

Flare of Duplication

How it works

1. Cast Arcbond by paying 2, targeting Bloodthirsty Conqueror.
2. Holding priority, cast Flare of Duplication by paying its mana cost or by sacrificing a nontoken red creature, 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 brilliant explosive loop hinges on the clever layering of Arcbond, which turns any damage dealt to a creature into a chain-reaction pulse hitting every player and creature on the board. By targeting both Bloodthirsty Conqueror and an indestructible creature with duplicate copies of Arcbond—conveniently facilitated by Flare of Duplication's ability to be cast for free by sacrificing a red creature—you set up a perpetual motion machine of destruction. Every time the damage spreads, Bloodthirsty Conqueror's mandatory life-gain trigger fires in response to opponents losing life, locking the board into an unstoppable loop that instantly drains the table to zero.
