I've been playing a sort of stompy for a while and I think that Chrome Mox is a great card in it. It allows you to cast two creatures on turn 1, its imprint doesn't matter so much in a deck like stompy. It has also great synergy with rogue elephant (for example 1st turn forest, elephant, mox, imprint something and you have still one mana available on you're 2nd turn even if you don't have an ESG or land grant in hand).

You should be running at least Hidden Gibbons, although, you don't like hidden things. Every deck has instants in it and it's especially good against control.
