I believe this could directly be a counter. You go head to head with Brome in the early stages but swarming out 2 drops. You drop Q on 6 mana (usually never flash it out, but could be worth it against Brome), then aim to play Decimus Spikes on 7 mana. Even if you don’t get Decimus in time for 7 mana you’ll have discarded a lot of Brome minions out of his deck and thinned your own to pretty much your own wincon with any left of Q’s, Warbeasts, Flash and Brillant Plumes.
Haven’t played the deck against Brome himself, but the deck worked pre-expansion and also worked post expansion. As long as you have Q, Decimus, Spikes, you can fill the rest of the deck with 2 drops if you wanted instead of having other things like Flash and Warbeast which don’t get removed post Q. I won’t be able to answer any questions since I’ll be away for the next day or so, once this is posted.
