well Belthazar666 i see your solution to my problems are full proof. Full sarcasm intended. Please do not run down my ideas like that, it is just simply my views, i do not need sarcastic and poorly thought of come backs to it. Now to run down your comment as you did to mine.
1.) Sometimes people do click continue without spinning the wheel for cards. It hapens. It's a mistake. I simply suggest a way to go back if that happens.
2.) Deck codes are a way to save a deck but that means you have to save it on a notepad of sorts and you cant exactly view them without having to recreate the deck. It is tedious to do such a thing. Where if you cold merely save a deck for future use and quick swapping, it would save time and effort.
3.) I pay attention to the game, but when multiple things happen at once you cannot exactly see everything. A suggestion to this problem could possibly be a log at the bottom of the game where it would say something like "(opponent) sent (players) (card name) back to deck with (card effect name)"
4.) I enjoy this game, i just think that half-bloods are a bit too much like false-gods, by toning down there health or something it could create more variety and a higher regard for beating false-gods.
5.) I did not know an auto mulligan feature was already there. I did not see it on the forums and it hasnt happened to me yet.
