The Perfect Organism

Deathtouch, Firststrike
Whenever there are 8 or fewer creatures on the battlefield (Including The Perfect Organism)
The Perfect Organism gains Indestructible and
Shadow. If The Perfect Organism is the only
creature on the battlefield you win the game.
You still don't understand what you're dealing with,
do you? The perfect organism. Its structural perfection
is matched only by its hostility. I admire its purity. A survivor. Unclouded by conscience, remorse, or
delusions of morality
