Battered Golem

Clock of Omens

Ancestral Statue

Chromatic Orrery

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Cast Ancestral Statue by paying 4.
3. Ancestral Statue enters the battlefield, triggering itself and Battered Golem.
4. Resolve the Battered Golem trigger, untapping it.
5. Activate Clock of Omens by tapping Battered Golem and Ancestral Statue, untapping Chromatic Orrery.
6. Resolve the Ancestral Statue trigger, returning it from the battlefield to your hand.
7. Repeat.
8. Once you have infinite mana, if you control a colored permanent, you may instead activate Chromatic Orrery's second ability to draw infinite cards.
