Extravagant Replication + Possessed Skaab + Walk the Aeons

Extravagant Replication

Possessed Skaab

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