Innovate (Whenever this creature would deal combat damage, you
may exile that many cards from the top of your library instead. If
you do, you may cast those cards until end of turn.)
At end of combat, if Goblin Wrencher has innovate and one or more cards are exiled with it, it loses innovate.
"Your first innovation is the one you should stick with."
