I always thought Selena had Speed closer to 80 than 60. I think it was Goodra's fault? That's another viable option for Selena's stats to line up with, except with swapped Attack and Defense stats.
Not that bad of a Special Attack...just lower compared to the other offensive characters (Mira, Andre and Dante have Special Attack stats that are at the very least least 100 IMO), that's all. If we're talking non-Mega terms...about 75 or 80....not sure what kind of Pokemon has a very high Attack (120 and up) and that kind of Sp.Atk. XD If the Pokemon has a Mega (or at least a theoretical Mega)...its Attack definitely has to be off the roof (150+)! XD Maybe swap Weavile's Sp.Atk and Sp.Def stats? XD
Yup, Evie obviously gets Greninja, hehe...it has the star weapon (though Evie's is bigger and she uses it as mostly a melee bladed weapon or for shorter-range throwing). Surprisingly, Mira actually works well with Sceptile...my favorite starter (it's all too known). XD Empoleon can also fit Selena, considering that it has good bulk (88 Def, 101 Sp.Def). XD Cis is a Support type and has Serperior's motif down pat though, so I think it's more like Cisrian - Serperior, Mira - Sceptile, Selena - Empoleon. Hey, it's the "Three Prides"! Dante is Charizard of course, while Jayden looks like the type who'd pick Blastoise. XD
How about...fossils! This should be interesting...who gets the bratty, tantruming T-Rex? XD No, not Archeops for Evie...she is not weak-willed. XD I can imagine Carracosta for Jayden and Omastar for Selena. XD
