I do thank you for your opinion, but are you basing on whether I should trade SOLELY on it's ability? (Which I got messaged on Facebook and was confirmed by Serebii that that hidden ability ONLY applies to the Altered Forme , Origin Forme still has Levitate

I mean, I know they're far from perfect, but the last Giratina I had never had a single IV higher than 9 so this one (from an IV standpoint) was much better (Max attack and HP, both Defenses 26 or over). I do thank you for your opinion and would definitely like to hear more about it, but isn't trading something with good to great IVs for something for no reason other than a better ability but may have consistently terrible IVs with every trade a little over reactionary?
