Extravagant Replication + Time Warp + Zealous Lorecaster

Extravagant Replication

Time Warp

Zealous Lorecaster

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