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 brilliant engine achieves infinite turns by recycling a single copy of Walk the Aeons indefinitely. Ramunap Excavator makes this loop possible by letting you replay your sacrificed lands directly from the graveyard, while Mystic Sanctuary acts as the crucial recursion piece to put the extra-turn spell right back on top of your library. As you consistently feed lands back into play, Aesi, Tyrant of Gyre Strait turns every land drop into a card draw that effortlessly plucks Walk the Aeons off the top of your deck so you can cast it all over again.
