Baby Uub giving out all the ass whooping’s. 

I think they'll be equal until UI Mastered goku will have slightly uper hand and frieza will step in and fuck Goku over so he gets his wish. Fuck frieza, should have been Buu or Uub in the tournament.

From everything I’m reading, the general consensus is that 129 will show the fate of the universes (who wins the tournament) but I have a different theory. Following DBS style, I think 95% of 129 will be unmastered UI and the last 30 seconds or so we’ll see the transformation to  Mastered Ultra Instinct. 

I think then we’ll have to wait to 130 to see full battle scenes of Mastered Ultra Instinct. 

tl;dr: 129 will reveal Mastered Ultra Instinct at the end, 130 will be first fight scenes with MUI Goku and the end of the tournament. 

Prediction for 129 & 130
