Slurrk, All-Ingesting + Simic Ascendancy + Saw in Half

Slurrk, All-Ingesting

Simic Ascendancy

Saw in Half

How it works

1. On the end step prior to your turn, cast Saw in Half by paying 2, destroying Slurrk and creating two 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. Put one Slurrk token into your graveyard due to the legend rule.
3. Each Slurrk triggers once, and Simic Ascendancy's first ability triggers twice.
4. Resolve both Simic Ascendancy triggers, putting ten growth counters on it.
5. Resolve the first Slurrk trigger, putting a +1/+1 counter on each creature you control that has a +1/+1 counter on it.
6. Simic Ascendacy's first ability triggers for each counter placed this way, putting that many growth counters on it.
7. Repeat from step 5 for the remaining trigger.
8. At the beginning of your upkeep, Simic Ascendancy's second ability triggers, causing you to win the game.

This clever setup uses Saw in Half to destroy Slurrk, All-Ingesting, triggering the legend rule to instantly send one of the resulting token copies to the graveyard while leaving the other on the battlefield. Because both the original Slurrk and its surviving token entered with five +1/+1 counters, their deaths and subsequent counter placements trigger Simic Ascendancy in a massive cascade that rapidly piles up twenty growth counters. When your turn rolls around, Simic Ascendancy's upkeep trigger resolves to hand you an immediate alternate-condition victory.
