is it possible to replace grommash or is it worth creating right now?

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...

spectacular. Thanks
