I feel it is a pain to set up the deck every single time and I agree that X is SMALL!
I have almost gotten a surrender error multiple times and sometimes the blockchain lags a bit and gives me a double submitted deck error, especially when I have to recalculate the mana cost everytime and the deck composition.
I would like to see enemy surrenders counted toward the win count.

On the newbie front and even for experienced users the jump from a deck of 1 stars to a higher ranked bronze player who has access to level 3 cards creates a gap that cannot be bridged and I would definitely agree that a newbie strategy guide should consider the aspect of trying to stay in the novice vs Bronze I league for a new player.

With a basic composition deck I feel it really does make it harder for new users to learn deck composition intuitively and needs a better tutorial, that said we are getting there one step at a time and I look forward to campaign mode which will address these issues.
