Teleportation Circle + Archaeomancer + Time Walk

Teleportation Circle

Archaeomancer

Time Walk

How it works

1. Cast Time Walk by paying 1, causing you to take an extra turn after this one.
2. At the beginning of your end step, Teleportation Circle triggers, blinking Archaeomancer.
3. When Archaeomancer enters the battlefield, it triggers, returning Time Walk to your hand from your graveyard.
4. Repeat each turn.
