I only have 4 more Legendary Pokémon to collect in X and Y (I don't care about Nature), and would like to enlist some help getting them:

Latias
Kyogre
Rayquaza
Manaphy

Of course I'd be trading you Legendary for Legendary! Here are the things I have to offer from which you can choose:

2 Articuno [Naughty/Mild]
Zapdos [Naughty]
Moltres [Lonely]
2 Mewtwo (no Stones) [Hasty/Timid]
Lugia [Modest]
Jirachi [Impish]
Giratina (No Orb) [Quirky]
Cresselia [Lonely]
2 Darkrai [Naive/Bashful]
Shaymin [Bold]

If you see anything you like, please let me know!
