Has anyone found any of the items needed for older forme changes?

-Deoxys's meteorite
-Rotom's appliances
-Giratina's Griseous Orb
-Shaymin's Gracidea
-Arceus's plates
-Kami trio's Reveal Glass
-Kyurem's DNA Splicers
-Keldeo's Secret Sword tutor
-Meloetta's Relic Song tutor

I will be disappoint if these are not all found in-game.
