I've recently taken to this game as well, but I'm relatively stuck at the moment. Right now, I am really disadvantaged against most other players when battling for treasures. I am curious how some people that are about my level (41) or close can have attack/defense ratings averaging 90 or so.
With even my best cards right now, the highest I managed was a mere 67, with about 20k attack points and 19k defense points.
I was thinking to evolve a Princess card to it's final form and enhancing it as much as possible. That plan isn't likely to work for some time, unfortunately, so... Any tips to help me?
