Underworld Breach + Malevolent Rumble + Purphoros, Bronze-Blooded + Cryptolith Rite

Underworld Breach

Malevolent Rumble

Purphoros, Bronze-Blooded

Cryptolith Rite

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 engine uses Underworld Breach to cast Malevolent Rumble repeatedly from your graveyard, utilizing its escape cost to constantly dig deeper into your library and fuel the graveyard for the next iteration. Cryptolith Rite provides the crucial mana production that lets your tokens tap for color while still holding their sacrifice ability in reserve, ensuring you can generate the mana needed to keep casting. Meanwhile, Purphoros, Bronze-Blooded grants haste to the Eldrazi Spawn tokens produced by Malevolent Rumble, allowing them to tap the very turn they enter the battlefield without waiting around.
