Oltec Matterweaver + Kor Skyfisher + Xorn

Oltec Matterweaver

Kor Skyfisher

Xorn

How it works

1. Cast Kor Skyfisher by paying 1.
2. Oltec Matterweaver triggers, creating two token copies of any Treasure token you control.
3. When Kor Skyfisher enters the battlefield, it triggers, returning itself from the battlefield to your hand.
4. Activate two Treasures by tapping and sacrificing them, adding 1.
5. Repeat.
