Walk the Aeons + Azusa, Lost but Seeking + Crucible of Worlds

Walk the Aeons

Azusa, Lost but Seeking

Crucible of Worlds

How it works

1. Play Islands from your graveyard until you control at least three Islands.
2. Cast Walk the Aeons for its buyback cost by paying 4 and sacrificing three Islands, taking an extra turn after this one.
3. Pass the turn.
4. Repeat.

This elegant loop grants you infinite turns by endlessly recycling your own real estate. With Crucible of Worlds active on your battlefield, you bypass the finality of sending lands to the graveyard, allowing you to replay those sacrificed lands right back out. Azusa, Lost but Seeking then does the heavy lifting of expanding your land drops so you can rapidly rebuild your mana base every single turn. Finally, Walk the Aeons leverages that recovered mana and territory to buy itself back to your hand, securing an endless succession of extra turns.
