I was playing against someone and I was about to destroy all creatures once my turn. The problems is the tokens it created said specifically that they can only block creatures with flying. But none of my creatures could block it. There was no other data showing why my sheoldred couldn't block a 10/10 token. I am assuming that the game code read it as "this creature can only be blocked by". Please fix this. I tried it to test the issue and it triggered that way for me 99% of the time against others.
