Oltec Matterweaver + Whitemane Lion + Jolene, the Plunder Queen

Oltec Matterweaver

Whitemane Lion

Jolene, the Plunder Queen

How it works

1. Cast Whitemane Lion by paying 1.
2. Oltec Matterweaver triggers, creating two token copies of any Treasure token you control.
3. When Whitemane Lion 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.
