I thought it was a pretty good episode. I figured that white aura was nothing more than a barrier, even though everyone speculated it being his new form. Honestly from the opening it just looks like he has completely mastered Kaio-Ken, rather than achieved a new form. Now if you're going to talk about the Dragon Ball Super manga, I would say his SS Blue appears to have been mastered, based on his fight with Merged Zamasu. To be honest I'm not really expecting any new specific transformation for a while. He can still power-up but will only be able to go so far, as Vegeta mentioned that they're already at the limits of their strength. I would really love to see more of the original Super Saiyan God (red form) than blue. While I enjoy blue it doesn't seem like red matters. Yet, in contrast it would save them stamina since blue drains pretty drastically, according to Goku.
About the episode, I really thought it was great. That ending sure was ominous though. Not only did it look like the angel (Mojito) was smiling after his universe got destroyed but also the Grand Priest. I feel like there's more going on behind the scenes. And after Goku requested the tournament it was the perfect opportunity for them to take action against Zeno, or use his powers to rid the remaining universes from existence. Either way it's definitely getting more interesting with each new episode!
