Underworld Breach + Malevolent Rumble + Temur Ascendancy + Springleaf Parade

Underworld Breach

Malevolent Rumble

Temur Ascendancy

Springleaf Parade

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 ingenious engine turns your graveyard into a self-sustaining loop by leveraging Underworld Breach, which grants every nonland card in your graveyard escape so you can continually recast your spells. Malevolent Rumble fuels this cycle by digging deep into your library, milling cards to keep your escape costs paid, and churning out the exact resources you need. Meanwhile, Springleaf Parade's static ability transforms those freshly minted tokens into mana sources, allowing you to tap them for colors and sacrifice them to pay for your repeated plays. Finally, Temur Ascendancy ties the room together with its static haste and powerful card-draw trigger whenever a creature with power 4 or greater enters the battlefield, turning your recursive milling into a cascading draw engine.
