Marut + Glaring Fleshraker + Cloudstone Curio + Peregrine Drake

Marut

Glaring Fleshraker

Cloudstone Curio

Peregrine Drake

How it works

1. Activate at least seven Treasures by tapping and sacrificing them, adding at least 7.
2. Cast Marut by paying at least 7 gained from Treasures, plus an extra up to 1 if needed.
3. Glaring Fleshraker's first ability triggers, creating a 0/1 Eldrazi Spawn creature token.
4. When the Eldrazi Spawn enters, Cloudstone Curio and Glaring Fleshraker's second ability triggers.
5. Resolve the Cloudstone Curio trigger, returning Peregrine Drake from the battlefield to your hand.
6. Resolve the Glaring Fleshraker trigger, dealing 1 damage to each opponent.
7. Resolve Marut. When Marut enters, it triggers, creating a Treasure for each mana from a Treasure spent to cast it.
8. Activate up to five lands by tapping them, adding at least 4.
9. Cast Peregrine Drake by paying its mana cost.
10. When Peregrine Drake enters, it and Cloudstone Curio trigger.
11. Resolve the Peregrine Drake trigger, untapping up to five lands.
12. Resolve the Cloudstone Curio trigger, returning Marut from the battlefield to your hand.
13. If needed, activate the Eldrazi Spawn by sacrificing it, adding C.
14. Repeat.

This loop dances between hand and battlefield by leveraging Glaring Fleshraker as both a damage engine and a token factory every time you cast a colorless spell. When you cast Marut—fueled by the mana from sacrificing your Treasures—Glaring Fleshraker triggers to spawn an Eldrazi Spawn, whose entry triggers Cloudstone Curio to bounce Peregrine Drake back to your hand. Recasting Peregrine Drake then untaps your lands to generate the mana you need while Cloudstone Curio bounces Marut right back to your hand, repeating the cycle. Meanwhile, Glaring Fleshraker's second ability ensures that every time a creature enters the battlefield, you melt your opponents' life totals away with inevitable damage.
