yeah this one is quite hard. i too lost a bunch with different decks had to handcraft a deck to counter it.
i used vaath:
3 rancour, 3 sunsteels, 2 nightwatchers (he will play his own nightwatcher so no reason to take rush minions), 3 plasma storm, 3, earthsphere, 2 grove lions (i only have 2, probably 3 would be better, this one is key here).
just try to survive and use forcefield + plasma storm to clear board later on when you stack bbs with forcefield it will be enough to just clear any minion he plays and you can concentrate on building enough minions to get the lethal.
Keep it up guys
