Ive been holding off on writing in this thread but I have to say it: Guys, the game is well balanced and fine. Any card you think is OP and poses a threat can be countered, you just need to find it, or plainly get better at the game. In a TCG/CCG, some cards will be better than others, thats the nature of the beast. You need to use that knowledge and just play more and more to understand the mechanics perfectly, to know all the cards available at any given turn to anticipate what your opponent might play.
Instead of trying to explain your failures by blaming "OP cards", be excited for upcoming new cards and learn this base card pool enough to be able to play the best you can! and remember to have fun!! 🙂
