OK, I guess I'll twitch some Hearthstone and then maybe you guys can give me a better idea of what I'm doing wrong?

So I watched three of your games. I wrote some of my criticisms in chat, but I'm not sure you saw them. One thing I noticed is that you don't seem to be thinking your plays all the way through. In one game your sequence of plays was:
>ping 4/1 blademaster
>Flamestrike
> Attack with 4/5 into 3/1 Auchenai
When the clearly better play was:
>Flamestrike
>Ping 3/1 Auchenai
In another game, the mage had 3 secrets. Mage has a few secrets that you need to test for before they screw things up for you. They can be tested for as follows:
>Ice Barrier or Vaporize > Hit Face
>Mirror Entity > play a weak minion
>Counterspell > play a weak spell or a spell that isn't essential
>Spellbender > play a spell on a MINION (the distinction is important)
>Duplicate > kill your opponent's weakest minion (or just ignore his minions; not always possible)
>Ice Block > Attempt to kill your opponent
You also seem to value the coin a bit too much. I usually use the coin to accelerate a 4 drop on turn 3 to smooth the curve. But multiple times you chose to play a two drop on turn 3 rather then coin out a perfectly serviceable four drop like yeti.
In the last game against priest that I watched you play, the priest cleared your board on turn 5, leaving you an empty board. So you chose to play river croc....and fireball him in the face? There was absolutely no reason for this play. The strongest play was to play one of your darkscale healers, but it was never a correct play to throw the fireball in his face. You should only start using burn on your opponent's face when it's going to kill him or if you're desperate.
These are just some of the things I saw watching you. Hope the advice helps.
