Crystalline Crawler + Simic Ascendancy + Vorinclex, Monstrous Raider + Conclave Mentor

Crystalline Crawler

Simic Ascendancy

Vorinclex, Monstrous Raider

Conclave Mentor

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 mesmerizing loop relies on Vorinclex, Monstrous Raider and Conclave Mentor to wildly amplify every single counter that enters the battlefield, turning a modest investment into an exponential explosion. When you activate Simic Ascendancy, those replacement effects multiply the incoming counters so heavily that Crystalline Crawler receives far more than you paid for. This surplus allows you to cash in just a fraction of those counters using Crystalline Crawler's mana ability to endlessly refund the activation cost for Simic Ascendancy while leaving plenty behind to rack up the required growth counters for an immediate alternate-win condition.
