RE: What Cards do You Want to See in the Next Set?
-Some reprinted trainers from previous sets and formats. Copycat, Pokemon Communication, Recycle, Revive, and more recently, Level Ball and Heavy Ball. There are probably others, but those are the big ones.
-The Eeveelutions we didn't get in XY3: Jolteon, Flareon, Vaporeon, Umbreon, and Espeon. I wouldn't mind seeing that Eevee from XY3 reprinted either (or at least something similar that makes getting it's Eeveelutions out easier).
-More draw/search supporters.
-Some more playable fairies. Preferably a stage 1 or stage 2 attacker (though I really like Mega Diancie EX)
-More unique special energy. I like what they're doing by giving each type it's own special energy with unique effects. I also wouldn't mind seeing Return Energy and Call Energy be reprinted.
-More ways to shut off abilities. There are too many broken abilities (especially those wall ones) and Garbodor is the only way to deal with them. Some ideas would be a Goop Gas Attack reprint in supporter form and a Pokemon with an attack that shuts down abilities for a turn.
-More Pokemon with attacks that affect all of your opponent's pokemon and not just the active. To give an example, we have a Pokemon with an attack that can shut down abilities for a turn (Arbok XY). The problem is that it only shuts down the opponent's active pokemon which opponent's can easily work around. Even if you can inconvenience an opponent, you'd almost always be better off just knocking them out instead of disrupting them. I don't think every type of attack should be like this (for instance, Gliscor XY4 would be too broken if it prevented opponents from attaching energy to any of their pokemon). It's just than in a format with Pokemon who can easily score KOs for such low costs, so many disruptive abilities are useless.
