Been playing since December and Ive enjoyed it so far, I enjoy the summon system as well as the team system In general. The art and battles are all really fun and Dokkan bosses are a good challenge even for me(And i have spent more than I care to admit lol...) You might be scared this is pay to win but it really isnt, you can spend $100 and walk away with fairly mediocre cards but get 20 free stones and get a top tier card all at random. I know plenty of f2p people who havent dropped a dime and still have comparable teams to my own. Great for traveling too, anytime Im stuck waiting at an airport or anywhere else I can pick up where I left off and kill some time.
