Extravagant Replication + Time Walk + Greenwarden of Murasa

Extravagant Replication

Time Walk

Greenwarden of Murasa

How it works

1. Cast Time Walk 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 Greenwarden of Murasa.
4. When the Greenwarden of Murasa token enters the battlefield, it triggers, returning Time Walk from your graveyard to your hand.
5. Repeat.
