Mind Control is a powerful and decisive card in Hearthstone, but it generate also a lot of frustrations. We can see all those topics about complains and nerf for this card.
So I propose this :
Imagine this card cost less mana around 7-8, but with a duration : only 2 turns for exemple.
By this way, this card will become a card to rebalance the game and not to finish surely.
Because at the end of the 2 turns there is 2 cases :
-your opponent get a lot of dammge with his best soldier.
-or his best soldier is dead because you turned it against the others.
What do you think ?...
