Hey guys so I recently started playing Hearthstone, fun as hell. So I'm trying to make a C'thun Hunter deck so obviously I open the Old God's pack and I unblox a legendary, Cho'gall but I don't know how to use him so should I either

A)Disenchant it and carry on with my Hunter C'thun Deck.
B)Make a mean Cho'gall Warlock deck but you guys will help me with that.
C)Disenchant and switch to another hero unless I Switch to warlock and it's B.
