Hey guys here's a thought. This is a promo. That means there is a chance for another full art in the set itself. Of course maybe not.
I think it's wrong though that they're doing this and yet they can't make a new card that features Professor Oak and make a full art out of that. He's THE Pokémon professor for crying out loud. And age is no excuse here, lest I point out the needless Team Rocket's Handiwork full art in Fates Collide. They're not a threat anywhere in the games, haven't been since HGSS unless one counts the 'threat' of Team Rocket in the anime.
Maybe it's me, but I would have preferred a full art of Lass's Recommendation, Shauna, or Misty's Determination instead.
