Everyone is talking about not using any decks but the meta but that is Yu-Gi-Oh and also any game you will play. Start a new account and you can absolutely get any (one) deck you want by feeding other cards. What really sucks about this game is the lack of any content at all. Solo gates are just dumb. They reward you with 2-card legacy packs that give you practically nothing. These are the same rewards from pvp -- which also isn't rewarding to play.
