Well I'm still stuck on what to do for you since I can apparently do half the OU tier If you still want a HP fighting Eevee I've got all the stuff ready for it since evan wanted one. I'd be really great if you had a list of the 5 you want most or something.
Isn't that ironic.... I have that EXACT skarmory, ut and impish. I am 99% sure I can trade it to you, but I will want the original back. Actually, my original is likely a clone anyway, so as long as I get one back, in good.
That is entirely up to you. Forry generally runs support, such as rocks, rapid spin, and spikes or toxic spikes, plus an attacking move or two. Thus it is natured to wall physical, special, or both. The stats suggest a physical wall, but it's plethora of resistances plus a few EVs can bolster the other side. How you do it depends on your team and preferences.
Hippowdon makes a good physical wall, and blissey is the obvious special wall. As for others, skarmory works, but the required moves are beyond me. Sigilyph works in lower tiers, and can pass in ou w/ proper support. Registeel is uu, but I do not have a flawless one. I've heard jellicent makes a good special wall, but I've never used one. I'm likely forgetting others. I guess shuckle if you lose a bet or something.
Draco Meteor would be easier over outrage. What about riolu, timburr, (brave, shiny, 31/31/31/x/31/0 w/ drain punch and mach punch), and a bagon of your specifications for gyarados, ferrothorn, and the rotom?
