This game is really good, like really good. After you get past the little bit of learning curve, and you figure out how the different card synergies work, this game starts to shine! Just about any deck can beat just about any other deck. Even, if you are like me, and are super new to the game. The early cards in the game hold up well against people that have cards from much later in the game. (It was in beta for a while so some people have most of the cards.)

It's NOT pay to win. Over time, you will unlock all the cards from pool 1 (Collector levels 1 - 214) Then over time you will unlock all the cards from pool two and so on. Can you speed up how fast you get through your collector levels, you can buy using RL money to buy the different variants for cards. But how the cards unlock is completely random. You might want that nice shiny Captain America card, but that card might not unlock right away for you. (In my case, it was Rocket Raccoon and now it's Ebony Maw... REALLY want that Ebony Maw Card.)

All and all it's worth your time, and worth your hard drive space. Also, 100% cross platform, so if you already have it on a mobile device, everything will carry over to your PC and vice versa.
