Hey Ive been playing this game for about a year now and I really love it but I think maybe you should make a monster trading system. Theres a lot of times I have a monster my friends want and I have one that they want. I mean maybe you could make monster trade tickets that cost 300 gems each so that you can still make a profit? Or even just adding them to an in game purchase pack?
