I remembered that whenever I download this game that I always uninstall it a couple days later. I wondered why, but now I remembered. The matchmaking is so unfair.. I always get set up agains people that have decks that counter ALL of my cards. And I've been stuck in Arena 9 for a very long time and barely ever win. I'm not planning on playing anymore if you don't change the matchmaking system to be at least a little more balanced.
