Underworld Breach + Malevolent Rumble + Insidious Roots + Shang-Chi, Master of Kung Fu

Underworld Breach

Malevolent Rumble

Insidious Roots

Shang-Chi, Master of Kung Fu

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 relies on Underworld Breach acting as your engine, granting escape to every card in your graveyard so you can recast Malevolent Rumble over and over by feeding it other resources. As Malevolent Rumble fills your graveyard and creates Eldrazi Spawn tokens, Insidious Roots steps in to reward you by generating Plant tokens whenever those cards leave your graveyard, while also turning your tokens into mana sources with its ability. Meanwhile, Shang-Chi, Master of Kung Fu provides the crucial haste and mana acceleration to untap and tap your growing token army without waiting. Together, these pieces turn a single escape spell into an endless engine of self-mill, token generation, and mana production.
