Rotlung Reanimator + Arcane Adaptation + Bloodflow Connoisseur

Rotlung Reanimator

Arcane Adaptation

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur by sacrificing any other creature.
2. When the creature dies as a Cleric due to Arcane Adaptation, Rotlung Reanimator triggers, creating a 2/2 Zombie creature token.
3. Resolve the Bloodflow Connoisseur ability.
4. Repeat.

This crafty loop turns a simple sacrifice outlet into an unstoppable engine by rewriting the very biology of your battlefield. With Arcane Adaptation naming "Cleric," every single creature you control—including the tokens you make—gains that type, allowing Rotlung Reanimator to see every single death as a fallen Cleric. Each time you feed a creature to Bloodflow Connoisseur, Rotlung Reanimator immediately replaces it by spawning a fresh 2/2 Zombie token, which can in turn be sacrificed to endlessly grow your Connoisseur with +1/+1 counters.
