hi, i am very sorry for the delay, ive been hit by some kinda wicked storm.
i have checked latios and latias, they are technically legal. however, i have some suspicions with owner Mat. he abused a shiny arceus, which is not allowed on pokecommunity. he also has some heavily edited pokemon. although some individual pokemon are legal and others are hacked, i consider Mat's collection to be totally worthless because of these past tendencies...
