Myr Battlesphere + Saw in Half + Mechanized Production

Myr Battlesphere

Saw in Half

Mechanized Production

How it works

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