Hey I need a deoxys, I have the following 'mons to trade (and pretty much every breedable mon in the game to).
Phione
Shaymin - lax & from Sinnoh, but might be a hack since the catch date is 4/21/2011.
Victini - Impish (defs not a hack since I caught it myself in the Liberty garden event when the games came out).
Cresselia - gentle
Virizion - sassy
Jirachi - jolly from SMR2010 event
Giratina - gentle
Lugia - mild
Palkia - relaxed + holding lustrous orb
Dialga - Brave
Terrakion - Lonely
Cobalion - Calm
Kyogre - Modest, japanese OT but apparently had a fateful encounter at lvl 100 - from Hoenn
Groudon - Adamant, also japanese OT and a fateful encounter in Hoenn, met at lvl 100.
Rayquaza - Lax with japanese OT from Hoenn
So yeah any deoxys for any one of the 'mons above, an event mon would be preferred if you want the victini though
