Extravagant Replication + Mnemonic Wall + Time Warp

Extravagant Replication

Mnemonic Wall

Time Warp

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 Mnemonic Wall.
4. When the Mnemonic Wall token enters the battlefield, it triggers, returning Time Warp from your graveyard to your hand.
5. Repeat.

This elegant chain achieves infinite turns by turning your upkeep into a self-sustaining engine of time itself. It all begins when you cast Time Warp to secure an extra turn, letting it fall safely into your graveyard. Once your next turn arrives, Extravagant Replication triggers at the beginning of your upkeep to conjure a brand new token copy of Mnemonic Wall. The moment that Mnemonic Wall token enters the battlefield, its triggered ability fires off to pluck Time Warp right back out of your graveyard and into your hand, ready to be cast again to start the cycle anew.
