Hi, So I was playing a minigame in King of Avalon where the troops aren't my real troops & there's duels with legion or something, & in the end I won some resources. They said "you can't earn reputation here" & was giving a few destiny cards to pick one of those at the end.

My question is where can I find the option to play that minigame again?? I don't find it anymore! I was really enjoying it.
