Vampire Charmseeker + Followed Footsteps + Time Warp

Vampire Charmseeker

Followed Footsteps

Time Warp

How it works

1. Cast Time Warp by paying 3, causing you to take an extra turn after this one.
2. Move to your next turn.
3. At the beginning of your upkeep, Followed Footsteps triggers, creating a token copy of Vampire Charmseeker.
4. The Vampire Charmseeker token enters the battlefield, returning Time Warp from your graveyard to your hand.
5. Repeat.
