Pursuit weak Scarfer me not like. To make me use Shaymin in a OU team someone needs to come up with a strong argument. I think ScarfRachi easily could do what ScarfCelebi could do and even better.

I really hate Blissey. Although i guess we could use it. Personal opinion Toxic and Thunder-wave is overkill. Non-stabbed Flamethrower is easily walled. Siesmic toss could go in here.

I've tested a combination of celebi and infernape and it actually work well,anyway what's the point of hp dark?starmie is OHKOed by Leaf Storm and if you use the spread 232 hp/ 244 spa/32 spe you can OHKO TTar (the speed ev allow you to outspeed jolly TTar),if u plan to taking on gengar,psychic is the most logical option (remember gengar poison typing?)I personally prefer grass knot but if u plan on using celebi,hp ice is the best option

I forgot Gengar were part-poison xD. So can anyone post a nice Celebi set? My were only complete theorymon.

What about a CM Seeder set?
It gets good enough atack, and a pretty nice defense, so after a couple of calm minds it's grass knot becomes very powerful, and he's also defensive enough to heal constantly and easily causing repeated switches.

Moveset:
~CM
~Leech Seed
~Substitute/Recover
~Grass Knot/Psychic

Nature: Bold

EV Spread:
252 HP / 220 Def / 36 Spe

That is a standart set.
I think that is OK, since it outspeeds jolly tyranitar.

What do you think of this?

If everyone posts a Celebi set i can make a poll saying for example "Ulvers Celebi set". That way i think we can find out which one to use.

Ulver's Celebi aka Tinker Bell w/ HP Fire and Recover
Celebi @ Life Orb
232 HP / 244 SpA / 24 Spe
Modest
-Thunderwave
-Leaf Storm
-Hidden Power [Fire] / U-turn
-Recover

Thunderwave is a given. U-turn against Scizor will give us a free Infernape set-up, but to me it just seems far too ambitious. Hidden Power [Fire] will simply kill the thing. Leaf storm will badly hurt Tyranitar or anything for that matter. Rest is an all-in-one healer and makes more sense than recover given the move set.
Edit: Recover put in over rest. Reasons in next two posts.

For celebi set I prefer Recover over rest thanks to the fact that Rest force you to switch,even with Recover only healing half your HP,I see it's more viable than Rest

I think I see your point. With recover healing is done first (before unloading leaf storm and becoming useless offensively), and then the opponent won't get a tempo on the switch out. That seems better. I'll edit it.

I would also suggest having U-Turn over HP Fire, because we already have infernape, with flamethrower or fire blast.

If we'll use that set maybe we can decide later what move to use? In the end we will have a better overview over the team.

That could work, but that means we are gonna include a celebi right? So are we gonna run Hidden Power Ice or Grass Knot?

Yeah Celebi seems like a nice choice to everone. GK or HP can also be decided later. Do you have a Moveset for Celebi, Zapdos?

Hmm,Celebi set that I ran is similiar to Ulver but I use HP fire instead,because with Infernape frailness,CB Scizor Bullet Punch still do around 40% and eliminate the scizor is more than enough to make Nape life longer

HP fire on celebi and HP ice on nape seems to cover the lot - celebi deals with scizor and nape deals with mence when the time comes.

I added Poll.

I'd personally go more offensive. After all, infernape comfortably kills T-tar back.

Moveset:
~Leaf storm
~HP Ice
~Earth power
~Psychic/Grass knot/energy ball

Nature: Timid
EV Spread:
252 SAtk / 252Spd /4 HP

I quite like Pastel's set now that I look at it. It fits more with my idea of a bulky multi-win-condition team. I'll think about it but it looks like my set might win the vote.
