Oltec Matterweaver + Kor Skyfisher + Elspeth, Storm Slayer

Oltec Matterweaver

Kor Skyfisher

Elspeth, Storm Slayer

How it works

1. Cast Kor Skyfisher by paying 1.
2. Oltec Matterweaver triggers, creating two token copies of any Treasure or Gold 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, or two Golds by sacrificing them, adding 1.
5. Repeat.
