Ancestral Statue + Kozilek's Unsealing + Kaya, Geist Hunter

Ancestral Statue

Kozilek's Unsealing

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Cast Ancestral Statue by paying 4.
3. Kozilek's Unsealing's first ability triggers, creating four 0/1 Eldrazi Spawn creature tokens.
4. When Ancestral Statue enters the battlefield, it triggers, returning itself from the battlefield to your hand.
5. Activate the Eldrazi Spawns by sacrificing them, adding CCCC.
6. Repeat from step 2.

This elegant loop turns the self-bouncing nature of Ancestral Statue into a self-contained engine for infinite resources. By fueling the Statue's casting cost with the mana from the Eldrazi Spawn tokens it helps generate, the loop becomes completely self-sustaining. The true brilliance of the combination relies on Kozilek's Unsealing to spew out those very Spawn whenever the Statue is cast, while Kaya, Geist Hunter doubles the token output to ensure you generate a net positive of mana and fodder with every single iteration.
