How it works

1. During an opponent's turn, activate Walking Atlas by tapping it, putting Ghost Town from your hand onto the battlefield.
2. Ghost Town enters the battlefield, triggering Toggo, creating a Rock equipment artifact token.
3. The Rock token enters the battlefield, triggering Battered Golem, untapping Battered Golem.
4. Activate Ghost Town's first ability by tapping it, adding C.
5. Activate Ghost Town's second ability by paying 0, returning it from the battlefield to your hand.
6. Activate Clock of Omens by tapping the Rock token and Battered Golem, untapping Walking Atlas.
7. Repeat.
