I am in the gold league but started playing after Exhien was the EX for the week. I never had a chance to obtain him. I have also lost literally every single round I go against him. In my hundreds of games I have never once beaten him no matter how buffed I am going in. I realize that some cards are better than others, and I would be ok if he were difficult to beat. But his power level is way above every other card in the game and since he is no longer obtainable I find it very frustrating to go against him. In the past have cards ever been changed?
