Can't finish the color challenge, so I try to report. Can't report the error unless I make an account. Can't make an account because of my username?, but they don't say if it's taken or how to solve it. Absolutely no customer service either. Way to push new players away. Oh, and everyone I play against has these ridiculous OP decks so I'm unable to get more XP to get better cards. You're better off buying a deck at your local hobby shop or Amazon and playing IRL.
