Throng is nice, but I don't think an aggro deck would ever need a 6-mana spell to actually win, it's a win-more card, I'd move it to the sideboard. I'd probably play Noggin' Whack main, and some removal, specially Nameless Inversion or that new UB spell that messes up combat math a lot. Also, I think rogues are better off in BR, with burn to push damage through.
