I’m just going to copy the comment I just made not sure if the people who work on this game will check out the forums more then the comments and who knows maybe someone has a solution for this already.
“I’m going to out on a limb and share my 2 cents on how you can improve this game and in particular the card formula system. Please for everything holy in this world just tell me if a card I have can be used in a combination. I don’t mind if it’s only the combinations I know of right now. I really need this so I can start trading out all these useless level 1 cards without worrying that I’m somehow screwing myself over on something really powerful later on. I just want a little screen to tell me “this card can be used in this combination that you already know of” I’m fine if you bring out new formula and I then find out my super useless card is mega important I just want to know that in the now im not giving up something that I shouldn’t give up without having to check one at a time every single time I want to give something up!"
Really do hope this gets solved as im sure im not the only one with this problem during all these holiday special gift giving hero card drops not to mention all those dame SEED!
