The royal championship arenas are most definitely rigged. when I first started playing the arena I didn't realize that after playing for a while it dawned on me that the games were a set up to let your opponents win there is no way that an opponent wins 80% of the time so I created my own strategy by leaving the arena when I'm ahead leaving the arena when the opponent gets boosters out of thin air etc etc. I realize now that opponents are pre determined.
