By casting Walk the Aeons, you secure an extra turn to set up your board and buy back the spell into your hand using its buyback cost, ensuring it is always ready to cast again. Kiki-Jiki, Mirror Breaker provides the engine for this loop, using its tap ability to continually manufacture haste-granting copies. Each time a token copy enters the battlefield, Salvager of Secrets immediately triggers to retrieve Walk the Aeons from your graveyard. Together, these cards create an endless succession of extra turns that completely lock your opponents out of the game.
