Onu, the Hundredth One

Indestructible, Reach
As long as you control 100 permanents, your life
total can't change and you and permanents you control have hexproof.
{1}: Create a 1/1 colorless servo artifact creature
token.
Uno's power is equal to the number of
permanents you control.
If Uno's power is equal to 100, your opponents
can't draw cards and can't gain life.
