Extravagant Replication + Time Stretch + Izzet Chronarch

Extravagant Replication

Time Stretch

Izzet Chronarch

How it works

1. Cast Time Stretch by paying its mana cost, causing you to take two extra turns after this one.
2. Move to your next turn.
3. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Izzet Chronarch.
4. When the Izzet Chronarch token enters the battlefield, it triggers, returning Time Stretch from your graveyard to your hand.
5. Repeat during your second extra turn.

This elegant engine locks down the board by chaining extra turns indefinitely, fueled by the relentless upkeep trigger of Extravagant Replication. Each cycle, Extravagant Replication duplicates Izzet Chronarch, whose enters-the-battlefield ability promptly salvages Time Stretch right back out of your graveyard. Because Time Stretch grants two extra turns per casting, you always have the necessary time to untap, deploy your copied wizards, and cast the spell again, leaving opponents indefinitely frozen out of the game.
