Actually, Mixi Maxes usually stays longer than a half of a match, the only reason that they disappear is because we can only have 3 MM at one time, and we will have to turn one of them off if we want a fourth one. Not to mention that Rei's Stamina is higher, he can stay in his MM form even longer. But yeah, I admit that Gamma does have an advantage in his Dribble hissatsu, even when it has to make up for his lower Dribbling.

And as you've seen in Episode 34, Perfect Cascade members can power up too, but not by training, by obtaining experiences after fighting with the opponent (Yup, sounds like a game to me XD) So, you can't just deny that Rei also leveled up too, just like Gamma. The only reason why he wasn't able to score againts Garu is because he's MF, his Kicking ability is not his main forte, so I can't blame him for that XD
