How it works
Activate Carrion Feeder by sacrificing Boonweaver Giant
When Boonweaver Giant dies, Fool's Demise's first and second ability triggers.
Resolve the first trigger, returning Boonweaver Giant from your graveyard to the battlefield
When Boonweaver Giant enters, it triggers, returning Fool's Demise from your graveyard to the battlefield attached to Boonweaver Giant.
Resolve the second Fool's Demise ability, doing nothing,.
Resolve the Carrion Feeder ability from step 1.
Repeat.
This ingenious loop turns Boonweaver Giant and Fool's Demise into a self-sustaining cycle of resurrection, fueled by the sacrifice outlet Carrion Feeder. When you feed the Giant to Carrion Feeder, Fool's Demise triggers to bring the Giant right back to the battlefield, which in turn lets the Giant fetch the Aura straight from the graveyard to reattach itself. Because Fool's Demise also safely returns to your hand if it ever hits the graveyard independently, the entire engine resets seamlessly while leaving Carrion Feeder permanently growing with infinite +1/+1 counters.
