I kept on going to Deatmatch > Extended25
But the opponents I am agaisnt are obviously not 25*
4 5* card right at hand. Second round same thing different cards. What???
Probroly not too many people in extended 25 so the game couldnt find you a match so it stuck you in dm extended
I guess this happens when you don't have any opponent matching the Extended25 format. Thus you get matched with whats available and in this case it was a guy using extended 40* format.
