Rakdos, the Muscle

Shambling Ghast

Haunted Crossroads

Prosper, Tome-Bound

Bartolomé del Presidio

How it works

1. Activate Bartolomé del Presidio by sacrificing Shambling Ghast.
2. When Shambling Ghast dies, it and Rakdos trigger.
3. Resolve the Shambling Ghast trigger, creating a Treasure token.
4. Activate the Treasure by tapping and sacrificing it, adding .
5. Holding priority, activate Haunted Crossroads by paying , putting Shambling Ghast from your graveyard onto the top of your library.
6. Resolve the Rakdos trigger, exiling Shambling Ghast from the top of your library with the ability to cast it until your next turn.
7. Resolve the Bartolomé del Presidio ability, putting a +1/+1 counter on it.
8. Cast Shambling Ghast from exile by paying 1.
9. Prosper triggers, creating a Treasure token.
10. Activate the Treasure by tapping and sacrificing it, adding 1.
11. Repeat.

This clever loop turns Bartolomé del Presidio into an engine of endless sacrifices by repeatedly feeding Shambling Ghast to him. Every time the Ghast dies, Rakdos, the Muscle exiles it right back to the top of your library while Haunted Crossroads provides the black mana needed to cycle it there in the first place. Meanwhile, Prosper, Tome-Bound turns casting the Ghast from exile into a net-positive resource loop by generating fresh Treasure tokens to sustain the mana requirements.
