What are the list of Pokemon you can't trade over GTS & through actual trades?

[That_Celebi__Person]

Reason I'm asking, I went to trade my rayquaza in Pokemon alpha sapphire since I have the event and it said i couldn't that there was a problem or something, so I tried my event Diancie and it wouldn't let it go through >.>.

Anyways! Can I not trade them? Cause neither my event rayquaza, my rayquaza, & Diancie didn't go through.

I found out that all legendaries can't be traded or event pokemon

Events (with ribbons) and certain pokemons (Manaphy, Meloetta, Mew, etc.) are special so they can't be traded over GTS.
Plus the ones on GTS are hacks.

I hope that'll be useful to you.
