Just started playing this when I'm on the go. It's pretty fun, card battle type game made by Square Enix. I'm still getting used to it. It's free to play, but like most freemium games you have the option to use real money to advance quicker, although it's not necessary

If you use the referral code MS69615 when you start the game it'll hook us both up for special rare cards, so that works for both of us. Also, feel free to add me in game name is Dude Huge we can help each other out.
