Verdurous Gearhulk + Saw in Half + Epic Struggle + Nested Shambler + Doubling Season

Verdurous Gearhulk

Saw in Half

Epic Struggle

Nested Shambler

Doubling Season

How it works

1. Cast Saw in Half by paying 2, destroying Verdurous Gearhulk and creating four token copies of it with base power equal to half the destroyed creature's power and base toughness equal to half the destroyed creature's toughness, rounding up each time.
2. When the Verdurous Gearhulk tokens enter the battlefield, they trigger, putting at least nine +1/+1 counters on Nested Shambler, and the remaining 23 +1/+1 counters on any creature(s) you control.
3. Kill Nested Shambler, triggering its ability, creating at least twenty 1/1 Squirrel creature tokens.
4. At the beginning of your next upkeep, Epic Struggle triggers, causing you to win the game.

This intricate engine transforms a single removal spell into an overwhelming army that secures your victory. You begin by using Saw in Half to destroy Verdurous Gearhulk, which thanks to Doubling Season generates four massive token copies instead of two. When these copies enter the battlefield, their ability is supercharged by Doubling Season's counter-doubling effect, allowing you to load an astronomical number of +1/+1 counters onto Nested Shambler. Once Nested Shambler perishes, its death trigger—again doubled by Doubling Season—spawns more than enough 1/1 Squirrel creature tokens to meet the twenty-creature threshold required by Epic Struggle, letting you easily ride its upkeep trigger to a win.
