Saw in Half

Mechanized Production

Doubling Season

Adrix and Nev, Twincasters

How it works

1. At the beginning of your upkeep, Mechanized Production triggers.
2. Holding priority, cast Saw in Half by paying 2, destroying a nonlegendary artifact creature you control and creating eight 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.
3. Resolve the Mechanized Production trigger, creating a token copy of the artifact it is attached to, and causing you to win the game.
