Oltec Matterweaver + Whitemane Lion + Kaya, Geist Hunter

Oltec Matterweaver

Whitemane Lion

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double all tokens you create this turn.
2. Cast Whitemane Lion by paying 1.
3. Oltec Matterweaver triggers, creating two token copies of any Treasure or Gold token you control.
4. When Whitemane Lion enters the battlefield, it triggers, returning itself from the battlefield to your hand.
5. Activate two Treasures by tapping and sacrificing them, or two Golds by sacrificing them, adding 1.
6. Repeat from step 2.

This ingenious loop harnesses Oltec Matterweaver's ability to duplicate artifact tokens whenever you cast a creature, letting you snowball your board state every time you deploy a threat. By activating Kaya, Geist Hunter's −2 ability, you double the output of those artifact tokens, turning every cast into a torrent of extra resources. Whitemane Lion acts as the perfect self-returning engine for this cascade, bouncing itself back to your hand upon entry so you can continuously recast it to trigger the Matterweaver all over again.
