It's free to play and not grindy. Hard, but rewarding.
Much better alternative to Hearthstone. Very new player friendly.
Truly F2P card game.
Best mobile ccg out
This is an awesome game with a major frustration. I am playing on a Galaxy Note8. I think it would only take a minor tweak in coding to allow S Pen use in game. It has very limited and frustrating performance for the S Pen. For example you cannot play cards or bring up your hand when the hand is in the low position. Fix that and it's a 5 star game.
One of the best TCG games, and the best one for mobiles. Tries to put randomisation to a minimum (looking at you Hearthstone), gives great rewards to the players, and also makes you actually think on the deckbuilding and playing the battles instead of the "always put the rarest ones in" type of gameplay
Star Pirates Infinity is a next-generation CCG set in a distant, chaotic galaxy.
