Extravagant Replication + Skullwinder + Walk the Aeons

Extravagant Replication

Skullwinder

Walk the Aeons

How it works

1. Cast Walk the Aeons 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 Skullwinder.
4. When the Skullwinder token enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.
5. Repeat.

This clever loop turns the steady cadence of Extravagant Replication into an endless succession of extra turns by taking advantage of token creation during your upkeep. Each time the replication creates a token copy of Skullwinder, its enter-the-battlefield ability triggers to fish Walk the Aeons right back out of your graveyard and into your hand. You can then simply cast Walk the Aeons again to secure your next turn, repeating the process indefinitely to lock down the game.
