Extravagant Replication + Eternal Witness + Time Stretch

Extravagant Replication

Eternal Witness

Time Stretch

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 Eternal Witness.
4. When the Eternal Witness token enters the battlefield, it triggers, returning Time Stretch from your graveyard to your hand.
5. Repeat during your second turn.

This breathtaking loop gives you all the time in the world by chaining extra turns directly into resource recycling. Once you cast Time Stretch to claim two consecutive extra turns, Extravagant Replication sets the engine in motion by spawning a token copy of Eternal Witness during your upkeep. Every time that token arrives, its enters-the-battlefield ability reaches into your graveyard to pluck Time Stretch right back to your hand, ready to be cast again. Because Extravagant Replication repeats this process on each of your extra turns, you lock down the game and ensure your opponents never take another turn again.
