Underworld Breach + Malevolent Rumble + Akroma's Memorial + A Realm Reborn

Underworld Breach

Malevolent Rumble

Akroma's Memorial

A Realm Reborn

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 your graveyard into an engine by leveraging Underworld Breach, which grants every nonland card in your graveyard escape so you can cast them over and over. By casting Malevolent Rumble from your graveyard for its escape cost, you dig through your deck, fill your graveyard back up with fuel, and continuously spawn token creatures. Meanwhile, A Realm Reborn helps manage your mana by turning your other permanents into color-fixing mana sources, and Akroma's Memorial sits proudly on the battlefield to grant your entire army a massive suite of keyword abilities.
