Cards of Pokemon that haven't had a shot of fame for like, ever? Golem has never been a competitive incarnation, example.
A much more diversed and balanced Weakness & Resistance system. There should be a good mix of various Weaknesses and Resistance to allow all types to shine equally. Just because Luxray GL is in the format basically means Water is 95% unplayable, except Gyarados, which apparently still loses to Luxray. That shows just how bad the balance is. More Water Pokemon should be weak to Grass, not just Feraligatr, and some weak to Metal, not just Glaceon and Regice. A few Fire Pokemon can be weak to Fighting since Rock in the DS games is catergorized under Fighting in the TCG. I can go on but I'm sure the idea is brought across.
