I just got a Druid deck with 5 Swipes in it. I felt really bad for this Hunter who I had four turns in a row where he filled his board and I destroyed all of them with a swipe. I feel like the deck is broken in that it is bad in the early game, and not great in the very late game. But it has so much removal, the opponent never has a chance to build a good and my sub-par creatures can finish them off (I have so many swipes in this deck, sometimes I just said it on the hero to kill off 2 or three minions with 1 health and then deal 4 to the hero - I can deal a serious amount of damage very fast this way).

Have you had any strange set-up decks from the Arena?

I drafted a Mage deck that offered me no spells... only memorable because it was absolutely worthless

@shortbreadtom: I had a draft which offered me a Malygos (Legendary with +5 Spell Damage) first (the only good legendary offered) but then didn't give me any damage spells (just a couple secrets like Ice Block). It actually made it quite funny as other players thought I was just holding my spells for then and so really focused their efforts on killing Malygos (ignoring the fact it was actually just a 4/12 for me, and the Boulderfist Ogres were better)

My most memorable draft ever was a mage with 4 Fireball, 4 Flamestrike, 3 Polymorph, pre-nerf Tinkmaster, and Ysera. 12-1.
