I hope for more Technician pokes with at least 100 Attack or Sp.Atk. base stats.
And also more No Guard pokes with at least 100 Attack or Sp.Atk., and be able to learn those inaccurate but powerful moves like Iron Tail, Thunder, Blizzard, Fire Blast, Focus Blast, etc...
Hopefully no OHKO moves for them, or battling will be too cheap.
And possibly Tri Attack TM or Move Tutor, especially for Togekiss, which benefits from that HAX effect, along with Air Slash. Speaking of flying types, Game Freak must make 100% accurate Special Flying-type attacks with at least 80 base power, and 100% accurate Physical Rock-type attacks.
Hopefully, some NU or UU Pokes will have an evolution...like Dunsparce or Jynx.
And if there are new Magic Guard pokes, they must have very good stats, unlike Clefable.
