Extra cards for priest
I'm all for seeing a logical discussion on the merits of card balance, but you're going to need to show why this "edge" is more of one than other classes posses and what really tips it out of balance. From a fatigue standpoint, as a priest, you have multiple ways to heal yourself which can easily result in a win from a board stalemate.
I don't see the problem here.
Every card gives you some form of power in exchange for casting it. You have made absolutely no case to argue that Thoughtsteal's power is excessive. It gives you two cards. On the plus side, yes, you don't draw through your deck to get them. On the minus side, it also does not thin down your deck the way normal draw cards do. Also on the minus side, they are cards from your opponent's deck, which will usually not fit into your own play as well as cards from your own deck.
also it's 3 mana and totally random. if you used it on a warrior, you could end up with a gorehowl or you could end up with a shield slam that does nothing since you can't gain armor.
it's a strongish card because it gives you hand advantage and it also has high potential, but it's not OP
finally i dont even understand your basic argument. fatigue? it does nothing to affect the number of cards drawn by either player before fatigue sets in.
