This classic Vintage-legal loop takes advantage of the recursive power of Archaeomancer paired with the delayed gratification of Conjurer's Closet. By letting Conjurer's Closet exile Archaeomancer at the end step of your turn, its entry trigger lets you pull Time Walk right back out of your graveyard and into your hand. Because Time Walk grants you an entirely extra turn to recast it, you can continuously repeat this cycle every single turn, completely locking the game down with infinite turns.
