Underworld Breach + Malevolent Rumble + Dynaheir, Invoker Adept + Enduring Vitality

Underworld Breach

Malevolent Rumble

Dynaheir, Invoker Adept

Enduring Vitality

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 loop revolves around Underworld Breach granting every nonland card in your graveyard escape, allowing you to cast Malevolent Rumble over and over by paying its mana cost and exiling fodder. As you churn through your deck with Malevolent Rumble, you generate Eldrazi Spawn tokens that can tap for mana via Enduring Vitality or sacrifice themselves for colorless mana to fuel your next escape. Meanwhile, Dynaheir, Invoker Adept sits on the board with her haste and copying prowess, turning this engine into an overwhelming storm of triggers that fuels itself indefinitely.
