Crystalline Crawler + Simic Ascendancy + Primal Vigor + Ozolith, the Shattered Spire

Crystalline Crawler

Simic Ascendancy

Primal Vigor

Ozolith, the Shattered Spire

How it works

1. Activate Simic Ascendancy by paying 1, putting four +1/+1 counters on Crystalline Crawler.
2. Simic Ascendancy triggers, putting growth counters on it.
3. Activate Crystalline Crawler's second ability by removing three +1/+1 counters from it, adding 1.
4. Repeat.
5. At the beginning of your next upkeep, Simic Ascendancy triggers, causing you to win the game.

This clever loop relies on a potent suite of counter-multiplying effects to turn Crystalline Crawler into a self-sustaining mana and growth engine. Both Primal Vigor and Ozolith, the Shattered Spire act as crucial static amplifiers, dramatically increasing the number of +1/+1 counters placed whenever Simic Ascendancy's ability targets the Crawler. Because these modifiers turn a single activation into a surplus of counters, you can strip away just a few using Crystalline Crawler's mana ability to endlessly recast the loop while leaving plenty behind to rack up growth counters on Simic Ascendancy for an alternate-condition victory.
