Extravagant Replication + Time Warp + Donnie & April, Adorkable Duo

Extravagant Replication

Time Warp

Donnie & April, Adorkable Duo

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 Donnie & April.
4. Put the Donnie & April token into your graveyard due to the legend rule.
5. When the Donnie & April token enters the battlefield, it triggers, returning Time Warp from your graveyard to your hand.
6. Repeat.

This looping engine turns a single extra turn into an endless succession of phases by continuously recycling your spells. You kick things off by casting Time Warp to claim your extra turn, which then sets the stage for Extravagant Replication to do its work during your upkeep. When Extravagant Replication creates a token copy of Donnie & April, the legend rule immediately sends the token to the graveyard, but its entry ability still triggers to return Time Warp right back to your hand. By repeating this process every turn, you can cast Time Warp indefinitely while continuously reaping the card advantage and recursion provided by Donnie & April.
