Extravagant Replication + Warden of the Eye + Time Warp

Extravagant Replication

Warden of the Eye

Time Warp

How it works

1. Cast Time Warp 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 Warden of the Eye.
4. When the Warden of the Eye token enters the battlefield, it triggers, returning Time Warp from your graveyard to your hand.
5. Repeat.
