DON'T BUY MYSTICAL CHESTS if you expect 9/10 stones. I have received 3 legendary and 1 terminator stones from 6 chests! I purchased the sale of 20 mystical chests because I need 10 #9 stones. I opened the first one and there was no #9 or #10 stones. I was playing this game long before the stones started but somehow I am not close to having enough #9 to rank or evolve once never mind 3 or 4 times. Others have full strength. Please let everyone play the game with the same opportunity to succeed.
