Repeat form step 6.
This devastating loop transforms a single ping of damage into an unstoppable, self-sustaining chain reaction. By using Fork to duplicate Arcbond so that both Bloodthirsty Conqueror and another indestructible creature are trapped in the crossfire, any initial damage dealt to the Conqueror triggers a web of collateral destruction. As Arcbond continuously damages every player and creature, Bloodthirsty Conqueror's passive ability triggers from the resulting life loss, creating an endless feedback loop that deals infinite damage and gains infinite life.
