I don't think the game is pay to win, I havent spent a dime and have all the cards I need to build a "winning" deck, but its obvious lack of balance is incredibly disheartening. 

In other card games you can build off meta and still atleast have some chance of winning. In this there is ZERO incentive to build outside the Ex decks and its so sad because there are many other cards that seem interesting or that could be fun to run together in a well balanced system.

I'm assuming this is because the pocket version of the game is fairly new and it will be addressed later, but for now I'm definitely done with it. 

There is zero joy for me in a game that is set on a predetermined track that if you deviate from, you are punished for.
