It's come down to this, but I'm choosing Team E. Chandelure has great Sp. Atk, Whimsicott hits hard with Giga Drain (but I might still get Lilligant if I trade for a Petilil in-game), I'll teach Gothitelle an Electric-type attack to cover for Electric-types. Initially I wasn't going to choose Unfezant (terrible Sp. Atk stat cos most of its movesets are Special-based) but Swanna has a 4x Electric weakness. Don't know if I should replace Whimsicott with Ferrothorn.
Personally I don't care for any of them altogether. I am not a fan of having two starters on the same team. I would got with Eelektross for Electric I am not to big on Zebrastrika tbh, Volcarona is going to take forever to raise so will Hydregion. I am using a Chandelure for my Ghost/Fire right now, pretty strong SP. Atk. I used Krookodile on my first run it was pretty good. Have you considered using Archeops? It has a pretty good movepool.
