Luvdisc's current stats:
Sp. Attack: 40
Sp. Def: 67
I predict luvdisc will have these stats or around this if it evolves:
Sp. Attack: 90
Sp. Def: 80
First off why 460? Well if you look at all the other prevolutions in the 330 range they all when evolve go from 460-530. Now being 530 is an Aggron I can't say its going to get those stats but at 460 both of its water buddies Lanturn and Lumineon exist with that stat. Luvdisc being like those 2 I resume it will have the same base stat.
Now in its life luvdisc only had one good stat which was speed so its evolution might have a really good speed. I think that maybe 120 is a good speed for this thing. Its attack sucked and I sort of want this to be good in battles so its attack will only go up 10 points. HP sucked aswell but a boost up too 70 isn't that bad same with the defense. Natually luvdisc had a decent 80 sp def so its gets and 80 after that a 90 sp attack stat and you get 460.
