Thomlir, Titan of Innovation

When Thomlir, Titan of Innovation enters the battlefield, noncreature artifacts you control
become artifact creatures with power and
toughness each equal to its mana value.
Whenever another artifact creature you control attacks, it gains your choice of a +1/+1, lifelink, firststrike, flying, vigilance, or trample counter.
"A shining star in a sea of stagnation."
