Rotlung Reanimator + Xenograft + Bloodflow Connoisseur

Rotlung Reanimator

Xenograft

Bloodflow Connoisseur

How it works

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

This clever loop turns your battlefield into an endless assembly line by manipulating creature types with Xenograft, which ensures that every creature you control counts as a Cleric. That type reassignment is what allows Rotlung Reanimator to spot every death and immediately replace the fallen with a fresh 2/2 Zombie token whenever anything perishes. You then feed those tokens directly into Bloodflow Connoisseur's activated ability, which not only fuels the sacrifice loop indefinitely but also piles up an endless stream of +1/+1 counters on the Connoisseur itself.
