Oltec Matterweaver + Whitemane Lion + Primal Vigor

Oltec Matterweaver

Whitemane Lion

Primal Vigor

How it works

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

This loop is a masterclass in self-sustaining momentum, turning the simple act of casting a creature into an infinite engine. When you cast Whitemane Lion, Oltec Matterweaver springs into action, and thanks to the doubling effect of Primal Vigor, you get double the token copies of whatever Treasure or Gold tokens you already have lying around. The Lion then triggers its own entry ability, bouncing itself right back to your hand so you can cast it all over again. Meanwhile, the mana from cracking those newly minted Treasures or Golds easily pays for the Lion's re-casting cost, leaving you with an endless parade of creature entries, leaves, and a massive storm count.
