Extravagant Replication + Time Stretch + Timeless Witness

Extravagant Replication

Time Stretch

Timeless Witness

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