Ancestral Statue + Kozilek's Unsealing + Anointed Procession

Ancestral Statue

Kozilek's Unsealing

Anointed Procession

How it works

1. Cast Ancestral Statue by paying 4.
2. Kozilek's Unsealing's first ability triggers, creating four 0/1 Eldrazi Spawn creature tokens.
3. When Ancestral Statue enters the battlefield, it triggers, returning itself from the battlefield to your hand.
4. Activate the Eldrazi Spawns by sacrificing them, adding CCCC.
5. Repeat.

This ingenious loop turns a self-bouncing automaton into an explosive engine for your board state. By repeatedly casting Ancestral Statue for four mana, you trigger Kozilek's Unsealing to pump out two Eldrazi Spawn, which Anointed Procession doubles into four tokens. Sacrificing those tokens generates the exact four colorless mana needed to recast the Statue, while its own entry trigger safely returns it to your hand to start the cycle anew.
