Geralf, the Fleshwright

Pitiless Plunderer

Ebondeath, Dracolich

Umbral Collar Zealot

Semblance Anvil

How it works

1. Cast Ebondeath from your graveyard by paying .
2. Geralf's first ability triggers, creating a 2/2 Zombie Rogue creature token.
3. When the Zombie Rogue enters the battlefield, Geralf's second ability triggers, putting a number of +1/+1 counters on the Zombie Rogue equal to the number of other Zombies that entered the battlefield under your control.
4. When Ebondeath enters the battlefield, Geralf's second ability triggers, putting a number of +1/+1 counters on Ebondeath equal to the number of other Zombies that entered the battlefield under your control.
5. Activate Umbral Collar Zealot twice by sacrificing the Zombie Rogue and Ebondeath.
6. When the Zombie Rogue and Ebondeath die, Pitiless Plunderer triggers twice, creating two Treasure tokens.
7. Resolve both Umbral Collar Zealot abilities.
8. Activate the Treasures by tapping and sacrificing them, adding .
9. Repeat.

This clever loop lets you endlessly recur Ebondeath, Dracolich from your graveyard for a cheap two mana, thanks to Semblance Anvil making your creature spells significantly cheaper to cast. Every time Ebondeath and the token generated by Geralf, the Fleshwright enter the battlefield, Umbral Collar Zealot is there to sacrifice them both back into the graveyard while setting up your next draw with surveil. Meanwhile, Pitiless Plunderer turns those constant deaths into a self-sustaining supply of Treasure tokens to continually pay for Ebondeath's return, letting Geralf grow an army of increasingly massive, counter-laden Zombies along the way.
