Rakdos, the Muscle + Priest of Gix + Haunted Crossroads + Semblance Anvil + Bartolomé del Presidio

Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Semblance Anvil

Bartolomé del Presidio

How it works

1. Activate Bartolomé del Presidio by sacrificing Priest of Gix.
2. When Priest of Gix dies, Rakdos triggers.
3. Holding priority, activate Haunted Crossroads by paying , putting Priest of Gix from your graveyard onto the top of your library.
4. Resolve the Rakdos trigger, causing you to exile the top three cards of your library with the ability to play them until your next end step.
5. Resolve the Bartolomé del Presidio ability from step 1, putting a +1/+1 counter on it.
6. Cast Priest of Gix from exile by paying 1.
7. When Priest of Gix enters the battlefield, it triggers, adding .
8. Repeat.

This infinite loop relies on cost reduction and recursion to generate endless mana, death triggers, and storm count. With Semblance Anvil exiling a creature card from your hand, your creature spells cost {2} less, allowing you to cast Priest of Gix from exile for just {1} mana while its enters-the-battlefield ability generates {B}{B}{B}. You use Bartolomé del Presidio to sacrifice Priest of Gix, sending it to the graveyard where Haunted Crossroads can cheaply put it back on top of your library in response. Rakdos, the Muscle then takes advantage of these endless sacrifices by exiling your library, allowing you to cast and play everything you need to seal the game.
