Extravagant Replication + Salvager of Secrets + Time Warp

Extravagant Replication

Salvager of Secrets

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 Salvager of Secrets.
4. When the Salvager of Secrets token enters the battlefield, it triggers, returning Time Warp from your graveyard to your hand.
5. Repeat.
