Yeah, but that guy did not mention anything about a scarf. Did you just feel like saying that out of the blue or did you make the same mistake I did and not realize that his jellicent is NOT a scarf variant and requires tailwind.Max Speed Timid Jellicent with a Choice Scarf outspeeds the genies and speedties with Whimsicott. No Tailwind needed.
someone had to say it
EDIT: Scarf/Tailwind/Max timid jellicent outspeeds whimsicott by one point. He hits 369, whimsicott hits 368.
EDIT: In response to your edit, I said it already...
You hit 332 Max with tailwind and scarf. If you run into any enemy tailwind teams, I think anything with over base 95 or maybe even 90 will beat you with TW support. So if you cut on the speed EVs, you may run into some trouble. Whereas, if you run timid, you hit around 369, which is a nice, high number. Infact, running timid lets you outspeed things like terrakion and base111s with tailwind support. This allows you to hit thundurus before he T-bolts you. Wait, actually, by my calculations, this allows you to outspeed WHIMSICOTT by 1 point. I suggest now that you change the nature, seeing as that would allow you a HUGE boost in speed. You would be faster than a Tailwinded whimsicott.
EDIT: Oh hold on, I thought you had scarf. Actually, with a modest nature, 252 EVs, and tailwind, you hit 220.... definitely not as awesome as it would be if it was Tailwind with a scarf.....
