B2 Battle Driod

{t}:Put a +1/+1 counter on each artifact
creature you control.
"Don't let the nickname fool you; the B2-series battle droid wasn't really all that super. Sure,
dthey had a level of strength and durability that
a B1 could only dream about, but they were slow
and clumsy, and they barely had enough processing power to aim their weapons in the right direction."
