Boonweaver Giant + Bloodflow Connoisseur + Changing Loyalty

Boonweaver Giant

Bloodflow Connoisseur

Changing Loyalty

How it works

1. Activate Bloodflow Connoisseur by sacrificing Boonweaver Giant
2. When Boonweaver Giant dies, Changing Loyalty triggers, returning Boonweaver Giant from your graveyard to the battlefield
3. When Boonweaver Giant enters, it triggers, returning Changing Loyalty from your graveyard to the battlefield attached to Boonweaver Giant.
4. Resolve the Bloodflow Connoisseur ability from step 1.
5. Repeat.

This clever loop revolves around Boonweaver Giant entering and dying in an endless cycle to generate infinite death, sacrifice, and entry triggers alongside infinitely large +1/+1 counters. Bloodflow Connoisseur acts as the sacrificial engine that powers the loop by feeding on your creatures and growing larger with each iteration. Meanwhile, Changing Loyalty ensures the entire engine keeps running smoothly by constantly returning Boonweaver Giant to the battlefield whenever it falls, while its own reflexive trigger catches the Aura as it follows the giant back into play.
