Underworld Breach + Malevolent Rumble + Jaheira, Friend of the Forest + Frostcliff Siege

Underworld Breach

Malevolent Rumble

Jaheira, Friend of the Forest

Frostcliff Siege

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 engine uses Underworld Breach to let you cast Malevolent Rumble repeatedly from your graveyard for its escape cost, fueling the loop by churning cards from your library straight into the bin. Jaheira, Friend of the Forest turns the Eldrazi Spawn tokens created by Malevolent Rumble into mana sources that can be tapped for green mana or sacrificed for colorless mana, helping pay for future escapes. Meanwhile, Frostcliff Siege pumps your team with its Temur mode while drawing you cards through its Jeskai mode whenever your creatures deal combat damage, turning your endless token generation into a devastating storm and self-mill advantage.
