Geralf, the Fleshwright

Pitiless Plunderer

Ebondeath, Dracolich

Centaur Omenreader

Phantom Train

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 Phantom Train 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 Phantom Train abilities.
8. Activate the Treasures by tapping and sacrificing them, adding .
9. Repeat.

This loop turns the recursive nature of Ebondeath, Dracolich and the sacrifice outlet of Phantom Train into an engine of endless rebirth, all while Centaur Omenreader quietly keeps your creature spells cheap (or helps power out initial costs). As your creatures die to feed Phantom Train, Pitiless Plunderer steps in to refund your mana in the form of Treasure tokens every single time. Meanwhile, Geralf, the Fleshwright tracks your spellcasting cadence and growing undead army, pumping out and continuously buffing fresh tokens to keep the loop fueled and your board terrifyingly large.
