Underworld Breach + Malevolent Rumble + Garna, the Bloodflame + Springleaf Parade

Underworld Breach

Malevolent Rumble

Garna, the Bloodflame

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 looping mechanism turns the graveyard into your personal hand through Underworld Breach, using escape to repeatedly cast Malevolent Rumble. Each iteration is fueled by the mana from Springleaf Parade, which turns your tokens into mana producers, and the Eldrazi Spawn token created by Malevolent Rumble itself. As the loop cycles, Garna, the Bloodflame can step in to reclaim your fallen creatures thanks to her enters-the-battlefield trigger and give your army haste, letting you churn through your library and generate massive value for a storm count or death triggers.
