I play acererack the archlich, I search through my deck and take insanely long to do so from time to time in order to put combos on the field for free. I ran out of time on my turn, which is fine I would have been okay, but had to discard cards and when you run out of time the ****** AI makes all the decisions for you. It defaulted discarding acererack into the graveyard and leaving him there, shutting down my deck as I didn't have tutors or recursion, and nearly causing me to lose the game. If my opponent didn't have good sportsmanship and exile my graveyard so that I can get him back in the command zone, I would have lost the game. Due to something that only exists on arena, I would have lost a competative game. Please do something to fix this.
