I'm very sceptic about this "add" First and foremost, let me say I have some training in making good adds, a year and a half of schooling infact, so let me point out some faults
-Nintendo is a professional company. I mean really, what kind of bland add retains a frame around the Nintendo store logo. That shot big red flags for me. Look around the logo, it's a giant box.
-Exclusive "Pokemon" Giveaway. Nintendo NEVER ever leaves Pokemon as that word in the title. They will always use the logo.
-Dialga and Palkia have no place on the add. Nintendo never puts the version Pokemon in adds (see mew add from Nintendo Power) If anything they would have all three starters+ Cress sillouette.
-Cress is a post National Dex Pokemon. Nintendo usually mantates National Dex for Pokemon of that such, and Cress seems a little random
-Cress needed wish. It was, excuse the pun, wishful thinking. To easily cause stir, they could just add it, like they did
-"if conditions met" is a grammar error. Nintendo as a professional company with a large printing budget would not need to save room by skipping words.
-The add is in black and white, Nintendo never does that. They always use magazine like paper in full color, and even on a black and white printer the color would show up.
-The heck, what's on the back sheet. If serebii would work for me I would complain to the thread starter to show me that back add.
I'd be very sceptic of this. Don't go changing any things on the site or on any simulators to reflect these moves until the day comes, or at least closer.
