Aesi, Tyrant of Gyre Strait + Walk the Aeons + Mystic Sanctuary + Perennial Behemoth

Aesi, Tyrant of Gyre Strait

Walk the Aeons

Mystic Sanctuary

Perennial Behemoth

How it works

1. Cast Walk the Aeons by paying 4, sacrificing Mystic Sanctuary and two other Islands, causing you to take an extra turn after this one and returning Walk the Aeons to your hand.
2. Play any Island except Mystic Sanctuary from your graveyard.
3. When the land enters the battlefield, Aesi triggers, allowing you to draw a card.
4. Move to your next turn.
5. Cast Walk the Aeons by paying 4, causing you to take an extra turn after this one.
6. Play any Island except Mystic Sanctuary from your graveyard.
7. When the land enters the battlefield, Aesi triggers, allowing you to draw a card.
8. Play Mystic Sanctuary from your graveyard.
9. When Mystic Sanctuary enters the battlefield, it and Aesi trigger.
10. Resolve the Mystic Sanctuary trigger, putting Walk the Aeons on top of your library from your graveyard.
11. Resolve the Aesi trigger, causing you to draw Walk the Aeons from the top of your library.
12. Move to your next turn.
13. Repeat.

This clever loop achieves infinite turns by repeatedly recycling Walk the Aeons using Mystic Sanctuary's landfall recursion, fueled by Perennial Behemoth's ability to play lands straight from your graveyard. Aesi, Tyrant of Gyre Strait anchors the engine by converting every land drop into a card draw, ensuring you can immediately pull Walk the Aeons back into your hand or onto the top of your library to cast it all over again.
