Yesterday, DANIEELA sent me a message saying that she had beaten twice my arena deck. I go and check and those were the only two games played. Needless to say, in platinum two losses and no wins mean getting out of the league.
I just opened Elements, spin the oracle and want to build an arena deck. However, when I get to the arena, I can see that my deck made yet another game and still is in play. It now is ranked 397 and effectively in play.
I posted this in troubleshooting instead of bugs because I think this was meant (my deck went under 500, a lot of decks in the Tier500 lost, and not many were submitted, and they went under me giving me a boost in order to enter the Tier500 where I played one game and won that), but I still think this isn't normal. If a deck falls out of the Arena it shouldn't be able to return, no matter what.
