Really fun episode. Cool that 17 finally got a moment to shine, but also a shame that it came at the cost of knocking out two characters that are more interesting than a Broly clone with a controlled form.
U2 characters are great and need to stick around for future stories.
That said, episodes like this continue to make me believe that the whole Universe erasing thing was a mistake. Super is at its best when it's not taking itself too seriously, and even throughout this arc its feeling like an afterthought, its been too goofy making moments when the serious part of it is actually brought up feel off.
I like the mix of both funny and dark at once.
I believe the universes that survive the tournament at all might be allowed to stay alive.
The ones that are erased will never come back. (Good riddance)
So that's 3 9 10 4 can say goodbye. 11 2 6 and 7 are safe IMO.
