Walk the Aeons + Mystic Sanctuary + Crucible of Worlds + Exploration

Walk the Aeons

Mystic Sanctuary

Crucible of Worlds

Exploration

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. Move to your next turn.
4. Cast Walk the Aeons by paying 4, causing you to take an extra turn after this one.
5. Play any Island except Mystic Sanctuary from your graveyard, then play Mystic Sanctuary from your graveyard.
6. When Mystic Sanctuary enters the battlefield, it triggers, putting Walk the Aeons on top of your library from your graveyard.
7. Move to your next turn, drawing Walk the Aeons during your draw step.
8. Repeat.

This ingenious loop lets you chain infinite turns right out of your graveyard, turning a modest mana investment into complete dominance across commander, legacy, oathbreaker, and vintage formats. The engine is anchored by Walk the Aeons, which buys its own return to your hand by sacrificing lands, while Crucible of Worlds ensures those sacrificed lands can be played right back out of your graveyard. Exploration provides the extra land drop needed to keep pace with the buyback costs. Finally, the synergy truly locks into place with Mystic Sanctuary, whose landfall ability recycles Walk the Aeons straight from your graveyard to the top of your library just in time for your next draw step.
