I'm talking perfect IVs/natures/movesets/abilities/EVs. Seems sort of foolish to spend countless hours on this ingame when you can just play on a battle emulator and accomplish the same thing in seconds o.O.
A very, very, very long time if you don't RNG. But really the hardest part is getting the IVs you want (and that may have been accelerated anyway). There are items for everything else. --- -Makin' it Rainbow: Water Gym Leader, Elite Divided- -3DS FC 2492 4122 0750-
You can coerce certain natures onto pokes with certain items/breeding etc. I just can't imagine the inhuman amount of time required to get optimal IVs x.x. But yeah, the amount of commitment it takes you make a competitive team/tons of subs other comps just ridiculous.
