Nick, Master Engineer

Whenever you cast an artifact spell, you may draw
a card. If you do, discard a card.

Inventor's Ingenuity — {1}{u}{w},{t}: Create a token
that's a copy of target noncreature artifact you
control. Sacrifice it at the beginning of the next
end step.

At the beginning of your end step, if you control
three or more artifacts, create a 1/1 colorless thopter artifact creature token with flying.
