Hearthpwn

brann and elise are in there for specific reasons, so you would have to find cards that don't have the same effect. i like the idea of doomcaller for if c'thun isn't the win condition (the lack of brann will make him usually smaller). i also like the idea of the 2/6 cow taunt with enrage. it just seems like a good card for warrior

i think it needs more card draw, and more hard removal, but great job with the deck

Would Entomb be a good replacement for Lightbomb? if not, what would be? excavated evil? confuse?

Dr boom is a tricky subject. It is going out of set rotation (if you don't know what i mean by standard and wild formats, please google it), so it's not valuable enough to craft unless you know you're going to play wild. at the same time, there really isn't a card like boom. it gives you board presence (3 minions), board control (the boom bots deal damage), and dr boom almost has taunt in a way (typically boom doesn't survive a full turn, so the opponent deals with it before your face). without boom, you're more likely to die, so i'd recommend either sludge number 2, or ice block. BUT, you probably wont be able to overcome the 1 turn clock, so it's hard. i'd say just pick a card you think is fun to play with.
