Well, if that question had been asked a few months ago, I'd have said craft just as an inclusion to your collection. But, since core set will be rotating out and we don't know which cards from Classic will stay, as well as the fact the Ooze will be rotating out... I'd say don't craft Grommash at all.
Instead, you could either run more things to combo with the Ooze or any other charger, just as a finisher. Personally, I'd go for either Reckless Rocketeer and cut some things to run the 3 mana 2/2 that copies a damaged minion or the 6 mana 4/2 with charge and divine shield...
I guess he is talking about the fact that you tell how you went to D5 and then you were stuck at D1 or whatever, but you do not write anything related to this deck ;)
Anyway, 95% of the people here should know how to play this deck, since its around since some time now.
