I came here to say just this. Mana Wyrm + Arcane Missiles does beat anything interesting you could do. Makes this brawl pointless and stupid in my book. Back to wild where things really are interesting.
After using Wyrm/Arcane to obtain the quick and easy book, I looked to Warrior, since its my only class not at 60.
MOLTEN BLADE + SHIELD SLAM. Go ahead and use the coin for your first shield kids. This one's fun. You have your multiple choice of all the great weapons, a powerful spell to take out just about any minions with at least 2 damage per turn. Confound your opponents with NO MINIONS in your deck (but you'll get some with select weapon choices). If you like weaponry, and a lot of choices, this is the deck.
Fun fun. Win win.
HAven't come up agains the wyrm deck yet, for 2 for 2 so far. :D
I have tried two interesting ideas unfortunately they cannot beat Wyrm + Missiles or Radiant + Mind Blast, so they're absolute trash. Got my free pack, won't be playing this awful brawl again. See you in a week.
