Tenacious Dead + Pitiless Plunderer + Gutter Grime + Bloodflow Connoisseur

Tenacious Dead

Pitiless Plunderer

Gutter Grime

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur by sacrificing Tenacious Dead.
2. When Tenacious Dead dies, it, Gutter Grime, and Pitiless Plunderer trigger.
3. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
4. Resolve the Gutter Grime trigger, creating a creature token.
5. In response to the remaining trigger, activate Bloodflow Connoisseur by sacrificing the creature token.
6. When the creature token dies, Pitiless Plunderer triggers, creating a Treasure token.
7. Resolve the Bloodflow Connoisseur ability from step 5.
8. Activate two Treasure tokens by tapping and sacrificing them, adding .
9. Resolve the Tenacious Dead trigger, paying 1 to return it to the battlefield from your graveyard.
10. Resolve the Bloodflow Connoisseur ability from step 1.
11. Repeat.

This self-sustaining loop turns a simple sacrifice into a massive engine by combining Bloodflow Connoisseur's repeatable sacrifice outlet with Tenacious Dead's ability to recur itself from the graveyard for a small mana fee. To fund that recurring cost, Pitiless Plunderer quietly manufactures a Treasure token every time a creature dies, ensuring you always have the black mana you need when Tenacious Dead's death trigger resolves. Meanwhile, Gutter Grime capitalizes on every fallen nontoken creature by steadily churning out growing Ooze tokens, which can themselves be fed to Bloodflow Connoisseur to fuel the loop even further or build an infinitely large threat.
