Underworld Breach + Malevolent Rumble + Phabine, Boss's Confidant + Jaheira, Friend of the Forest

Underworld Breach

Malevolent Rumble

Phabine, Boss's Confidant

Jaheira, Friend of the Forest

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 feeds on the recursive potential of Underworld Breach, using its escape mechanic to repeatedly cast Malevolent Rumble from your graveyard while churning through your library. Jaheira, Friend of the Forest provides the crucial mana engine that lets your Eldrazi Spawn tokens tap for green mana in addition to being sacrificed for colorlessness, perfectly funding the escape cost. Meanwhile, Phabine, Boss's Confidant adds a powerful passive anthem and haste to your token army, leveraging the endless stream of creature creations into a massive, game-winning board state.
