Underworld Breach + Malevolent Rumble + Enduring Vitality + Lavaleaper

Underworld Breach

Malevolent Rumble

Enduring Vitality

Lavaleaper

How it works

1. Cast Malevolent Rumble for its escape cost by paying 1 and exiling three other cards from your graveyard, causing you to mill at least three cards and create a 0/1 Eldrazi Spawn creature token.
2. Activate the Eldrazi Spawn by tapping it, adding .
3. Activate the Eldrazi Spawn by sacrificing it, adding C.
4. Repeat.

This loop turns a graveyard into an endless engine by leveraging Underworld Breach, which grants escape to every nonland card you cast. Malevolent Rumble fuels this escape cost by digging into your library, seeding your graveyard with fresh fodder, and manufacturing the Eldrazi Spawn tokens needed to generate mana. Both Enduring Vitality and Lavaleaper play vital passive roles here: Enduring Vitality grants your creatures the ability to tap for mana, while Lavaleaper ensures that the basic lands and permanents in play amplify your mana production to sustain the continuous casting loop.
