Teleportation Circle + Mnemonic Wall + Temporal Manipulation

Teleportation Circle

Mnemonic Wall

Temporal Manipulation

How it works

1. Cast Temporal Manipulation by paying 3, causing you to take an extra turn after this one.
2. At the beginning of your end step, Teleportation Circle triggers, blinking Mnemonic Wall.
3. When Mnemonic Wall enters the battlefield, it triggers, returning Temporal Manipulation to your hand from your graveyard.
4. Repeat each turn.
