Random chance in battle

Ever since the tournament ended this weekend, the battle rewards and outcomes have become more snd more random. Now soemtimws my battle timer will go all the way down to 0 and it’ll give me an option to fight an AI. And on Tuesday, in one battle I only won ONE trophy, and as a guy who is trying to save cash for the one time offer from the Jurassic ruins, that was super frustrating. And then jn another battle, I won 55 trophies. So they seem to be a lot more random Now.
