I hope you like being locked into the tutorial forever. So after the main tutorial, you have to do the "Color Challenge", where you use a specific colored deck and battle NPCs. Your final match is supposed to be a PVP match, and after completing that you unlock the rest of the game. However, that final PVP color challenge match doesn't work for ANY new players. Do a quick Google search and you'll find that literally anyone new to the app cannot play beyond the color challenge. Avoid this app.
