Nissa, Hater of Fun

Reach, trample
{g}{g}: Destroy target artifact with converted mana cost less than the amount of forests you control.
Whenever an artifact an opponent controls leaves the battlefield, put a +1/+1 counter on Nissa.
When Nissa discovered the Auto-god's caves, she was furious. After all, this was her background set! And the name "Inspector Gadget?" Really?
