I've since took a page from noel's book and made a cosmic power/minimize/stored power clefable that steamrolled her team, I was really surprised how smooth it went. I notice that gym leaders, for me at least, are either a 2 or a 10 in terms of difficulty. Like, People like Florinia Serra and Aya made me rage quit the game for weeks, but like, radomus luna and terra I beat on my first try. I don't know if I'm just adjusting to Reborn's difficulty or it's just because I have more resources now. I will say, it's much much easier to build a sweep in a single battle
