Was good at 1st but now over run with hackers and 95% players only use the top winning decks meanin there is no use tryin to build up own deck becuz u cant even play a card unless u have negates to negate up opponents negate trust me the app is just a ball of frustration would say maybe better irl but I wouldn't waste time with YuGiOh when there r better structured TCGs out there Magic The Gathering Pokémon Vanguard just to name a few of the most popular
