Or, if you want to go full rush and rely on that Molten+Charge combo, maybe it'd be better to include Alexstraszha instead of Ysera to set up for the fast kill.
molten giant shouldnt be used as a finisher anymore. thats what grom is for. replace those charges with 2 DoAs.
no reason to have korkron and chillwind. if ur getting doa with ur giants, then go with chillwind. put frothing, harvest golem, or earthen ring farseer in the korkrons place.
remove inner rage for taskmaster, and cleave for acolyte. cleave is an ok card at best. but youd rather have more card draw so you can get up to your big finishers.
argent commander is iffy. its not really necessary, since you already have huge late game guys like molten giant, grom, and ysera. you can keep them, but personally, id get some gadgetzan auctioneers.
the issue im seeing with your deck is that your late game is heavily loaded but your early game is pretty much non existent.
