Archaeomancer + Erratic Portal + Walk the Aeons

Archaeomancer

Erratic Portal

Walk the Aeons

How it works

1. Cast Walk the Aeons by paying 4, taking an extra turn after this one.
2. Cast Archaeomancer by paying 2.
3. Archaeomancer enters the battlefield, returning Walk the Aeons to your hand.
4. Activate Erratic Portal by paying 1 and tapping it, returning Archaeomancer to your hand.
5. Move to your next turn.
6. Repeat.

This elegant loop hinges on leveraging Archaeomancer's enter-the-battlefield trigger to continuously reclaim Walk the Aeons from your graveyard, ensuring you can chain extra turns indefinitely. To reset the Wizard without burning through your entire hand, Erratic Portal provides a neat mechanical escape hatch, bouncing Archaeomancer back to safety for a modest mana investment. Because Erratic Portal's ability allows you to choose your own creature, you can bypass the "unless its controller pays {1}" tax entirely by simply choosing not to pay it yourself, neatly returning the spell-fetching creature to your hand so the whole cycle can begin anew.
