Used to love using this app whenever I went to my local card shop to play Yugioh. Even at home with friends it would be the absolute BEST app, but for the past 2 or 3 months it just NEVER opens. I press to open the app and it just kicks me out instantly. Get it to be working again and it's definitely going to be a 5 star rating again from me. It has everything you could need for a duel, but not so much these days.
