Lumra, Bellow of the Woods + Walk the Aeons + Brago, King Eternal

Lumra, Bellow of the Woods

Walk the Aeons

Brago, King Eternal

How it works

1. Cast Walk the Aeons for its buyback cost by paying 4 and sacrificing three Islands, causing you to take an extra turn after this one and return Walk the Aeons to your hand.
2. Blink Lumra using Brago.
3. When Lumra enters, it triggers, causing you to mill four cards and then return all land cards from your graveyard to the battlefield tapped.
4. Repeat each turn.
