Extravagant Replication + Vampire Charmseeker + Temporal Manipulation

Extravagant Replication

Vampire Charmseeker

Temporal Manipulation

How it works

1. Cast Temporal Manipulation by paying its mana cost, causing you to take an extra turn after this one.
2. Move to your next turn.
3. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Vampire Charmseeker.
4. When the Vampire Charmseeker token enters the battlefield, it triggers, returning Temporal Manipulation from your graveyard to your hand.
5. Repeat.
