Mnemonic Wall + Followed Footsteps + Time Walk

Mnemonic Wall

Followed Footsteps

Time Walk

How it works

1. Cast Time Walk by paying 1, taking an extra turn after this one.
2. At the beginning of your upkeep, Followed Footsteps triggers, creating a token copy of Mnemonic Wall.
3. Mnemonic Wall enters the battlefield, returning Time Walk to your hand.
4. Repeat each turn.
