Basically, I think this season prize is useless for just about everybody.
I think anybody over 4000 Trophies has discarded Miragaia for better dinosaurs. while the hybrid Dsungaia is impossible to build, due to the lack of the arena exclusive Dsungaripterus. I believe anybody building the hybrid has Miragaia in excess.
So what level of trophies did you stop using Miragaia, and it you are using Miragaia, what trophy level are you?
