Need help with my pokedex!

I'm trying to complete my pokedex and need some help. Currently I've acquired 480.

I need the following:

No. 250 Ho-oh
No. 251 Celebi
No. 385 Jirachi
No. 464 Rhyperior
No. 466 Electivire
No. 467 Magmortar
No. 474 Porygon-Z
No. 477 Dusknoir
No. 489 Phione
No. 490 Manaphy
No. 491 Darkrai
No. 492 Shaymin
No. 493 Arceus

I don't neccesarily need them for keeps just for pokedex entry purposes. I'd trade them right back. Any help would be great. I've got a lot of pokemon too. I'd be happy to return the favor.

i can give you ry pherior and electivire and maybe darkrai
