Crystalline Crawler + Simic Ascendancy + Loading Zone + Brad Boimler, Eager Ensign

Crystalline Crawler

Simic Ascendancy

Loading Zone

Brad Boimler, Eager Ensign

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 intricate loop centers around Crystalline Crawler, which provides both the mana to fuel Simic Ascendancy's activation cost and the +1/+1 counters that feed its win condition. The true engine that turns this into a game-winning powerhouse, however, is Loading Zone combined with Brad Boimler, Eager Ensign, whose replacement effects multiply the counters placed on your creatures far beyond the base rate. By tapping Brad Boimler, Eager Ensign and casting Loading Zone for its warp cost, your counter production snowballs so aggressively that Simic Ascendancy rapidly accumulates the twenty growth counters needed to trigger its alternate win condition at the beginning of your upkeep.
