I think I'd like the additional HP over the SpD, if only it would allow Flareon to stay in on physical attackers better. Either way has its advantages of course.
Plus you did say non-SE hits, so I went with that while going with common UU threats, as Flareon wouldn't exactly make it too hot in OU. Victini is #3 in usage while Chandelure is #11, so I figured they would be good candidates for such a scenario.And yes, I was bored and did all that.
