Pokemon Masters EX - Battle Rally Dump 24

I'm playing Pokemon Masters, a mobile gacha game set on the island of Pasio. Collect many Pokemon waifus and husbandos and participate in unique battles involving sync pairs.

I'm finding it really hard to unlock EX roles. But not because I'm low on Role Cakes (I have a good amount). I just don't know who to upgrade. Many units I seldom sync with, like Anniversary (Anni) May, Anni Lillie, Anni N, and Rei. Then, there are units which I sync with all the time, but their EX Role is useless, like Neo Champion (NC) Blue and NC Calem. I think my next targets are Sygna Suit (SS) Lusamine, Red, and SS Nemona. I don't use these units much in Battle Rally, but maybe I would use them more if I had their EX Roles unlocked.

Thanks for watching!
