IIdk, maybe the Legendary League is the reason, but the game has turned into another Clash Royale: if you don't want to change your army, you are going to face a fixed set of minis in opponent's team that destroy your army in a moment
I disagree. I'm at 800 trophy range and that never happened. There isn't really a matchmaking algorithm from what I see. Also just use RG. A 3-Star Royal Ghost can wipe out an entire team.
