Mystic Retrieval + Runic Repetition + Walk the Aeons

Mystic Retrieval

Runic Repetition

Walk the Aeons

How it works

1. Cast Walk the Aeons by paying 4, causing you to take an extra turn after this one.
2. Cast Mystic Retrieval by paying 3, returning Runic Repetition to your hand from your graveyard.
3. Cast Mystic Retrieval from your graveyard for its flashback cost by paying 2, returning Walk the Aeons from your graveyard to your hand and exiling Mystic Retrieval.
4. Cast Runic Repetition by paying 2, returning Mystic Retrieval from exile to your hand.
5. Repeat each turn.

This loop relies on a clever recycling chain to take infinite turns, utilizing Walk the Aeons to grant you the extra turns you need while keeping your mana and resources flowing. Because Walk the Aeons goes to the graveyard upon resolution, Mystic Retrieval can pull it right back out, and its flashback ability allows you to cast it a second time from the graveyard before it exiles itself. Once Mystic Retrieval is safely in exile, Runic Repetition steps in to retrieve it, completing the seamless circle that returns all your key spells back to your hand to be cast over and over again.
