Wow,I loved it. I thought PA,BE and Aflatoxin was a must for CCYB,and you have them. It has a lot of cards and this is the problem. But they are all must-have,that is annoying.
(Btw,I have been playing Elements for ages and I don't know why I didn't register before.)
Edit:I just want to share how PA saved my life.I used it on my towers at the beginning,Seism couldn't touch my towers and it was an easy win for me
