Extravagant Replication + Time Stretch + Zealous Lorecaster

Extravagant Replication

Time Stretch

Zealous Lorecaster

How it works

1. Cast Time Stretch 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 Stretch from your graveyard to your hand.
5. Repeat during your second extra turn
