Elesh Norn, Mother of Machines + Ancestral Statue + Clock of Omens + Nyx Lotus

Elesh Norn, Mother of Machines

Ancestral Statue

Clock of Omens

Nyx Lotus

How it works

1. Activate Nyx Lotus by tapping it, adding at least 4.
2. Cast Ancestral Statue by paying 4.
3. When Ancestral Statue enters the battlefield, it triggers twice.
4. Holding priority, activate Clock of Omens by tapping the nontoken noncreature artifact and Ancestral Statue, untapping Nyx Lotus.
5. Resolve both Ancestral Statue triggers, returning it and the nontoken noncreature artifact to your hand.
6. Cast the noncreature artifact by paying its mana cost.
7. Repeat.
8. If the noncreature artifact has a mana value less than the largest amount of devotion to a color you have minus four, this combo nets infinite mana.
