Underworld Breach + Malevolent Rumble + Enduring Vitality + Frostcliff Siege

Underworld Breach

Malevolent Rumble

Enduring Vitality

Frostcliff Siege

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 fascinating self-sustaining loop relies on Underworld Breach to grant escape to everything in your graveyard, turning your discard pile into an active hand. Malevolent Rumble fuels this engine by filling the graveyard while churning out Eldrazi Spawn tokens, which Enduring Vitality then empowers by granting them a mana-tapping ability on top of their natural sacrifice mana. Meanwhile, Frostcliff Siege pumps up your board and draws you cards when dealing combat damage, rounding out a relentless loop that generates infinite self-mill, death triggers, and storm count.
