Parasect, Hypno, Luxray and Herdier can't be caught in Friend Safari. Paras, Drowzee, Luxio and Lillipup can, though. But they would need to be leveled up in order to evolve and be legal. Same with Gothitelle, it can't be caught in Pokemon Village, but Gothorita can be caught.
Togetic is not a Dream World Pokemon, but Togekiss is. It was only available in BW, not B2W2. And it has the wrong moveset and wrong gender.
Shiny Haxorus is caught at level 60, not 57.
Nothing is wrong with the Xerneas, it only shows Unable to match a Mystery Gift error because the wondercard isn't in PKHeX's database yet.
