I've just started playing a control Shaman, and whilst I get used to it (and save up another 190 dust for my 2nd Earth Elemental), I've been testing things out on unranked. My opening hands in this game were actually fairly poor, though I still managed to stop him/her from totally snowballing early on.
Anyway, round 8 hits and he drops Ragnaros -> I hex it. Round 9, he drops Antonidas -> Hex, a couple of rounds later he dropped Onyxia -> +1 Lightning Storm clears the whelps and hits Onyxia for 4, I finish her off with my Azure Drake. By this point I was laughing at (a) How bad s/he was, and (b) How good she thought her deck of legendaries was. I could literally feel the anger and frustration coming through the screen. I baited a Polymorph with an Earth Elemental, and then dropped Ysera, hoping to bait out the 2nd (I had Raggy and a Faceless Manipulator in my hand). No polymorph, so Ysera quickly begins to snowball. A few rounds later, s/he drops his/her own Ysera -> 2x Lava Burst to the face and then finished her off with a Feral Spirit. I then proceeded to drop Ragnaros and finish the game. I felt kinda sorry for the rude awakening my opponent received, but had to laugh at just how bad his/her deck and plays were, and how infuriating it must have been for him/her.
