Underworld Breach + Malevolent Rumble + Cyclops of Eternal Fury + Insidious Roots

Underworld Breach

Malevolent Rumble

Cyclops of Eternal Fury

Insidious Roots

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 clever loop turns Underworld Breach into a relentless self-milling engine by giving every card in your graveyard escape, allowing you to repeatedly cast Malevolent Rumble. As Malevolent Rumble fills your graveyard and creates Eldrazi Spawn tokens, Insidious Roots steps in to capitalize on the chaos: whenever cards leave your graveyard, it spawns Plant tokens that can tap for mana to help pay your escape costs. Meanwhile, Cyclops of Eternal Fury is along for the ride, granting haste to your growing army of tokens as you dig deeper toward your win condition.
