While not the best episode of the Tournament, I have to say this is the one that captures the the feeling of a Battle Royale the best. Two great fights going on at the same time, between no less that 10 characters? That's what I was waiting for this whole time and it finally delivered on that front! A truly great spectacle!
The transformation of the U2 guys floored me! I never expected such a thing

Too bad they couldn't have been unique in their own right, but they proved more than welcomed. At least they weren't completely fodderized.
The Namekians were awesome too. Not the flashiest or strongest characters there, but I enjoyed them quite a bit! Their fight against Piccolo and (mostly

) Gohan was the highlight for sure. Really liked how their teamwork functioned. They almost got Ultimate Gohan too, till my boy came to the rescue with that awesome Makankosappo.
Speaking of Piccolo, his internal struggle regarding this fight was pretty well handled. While he didn't actually throw a lot of punches, it still felt like his battle trough and trough. Loved the Nail and Kami cameos. Very atmospheric and cool.
Goku was awesome in how he dealt with that Black Hole thing and the direction with the two Kamehamehas was sooo on point.
As someone else mentioned, I like how every Universe is taking their loss in different ways. It makes the event feel all the more special than if everyone whined everytime. Which brings me to how I think the U6 erasure was done very well. It was still emotional, but I like they didn't go the sappy route. That would've felt way too forced, especially at this point. It was very in tune with the series as a whole.
If there's one complaint I have is that it could've used more screentime, since U2 got a fair share more, but since we've been getting a lot more U6 in the stands and we know a lot more about them than U2, I guess it's understandable why they went that way.
The little 17/18 "villain" introductions was very funny too. Their role in U2's defeat was pretty crucial. Will be interesting to see where they go from here with them.
Next episode looks like another fight on multiple fronts, so I hope it manages to capture the feeling of the Battle Royale at least half as well as this one did. That NEP gives no clues as to who's going out from U7, so it will be a tough wait!
