usable items that increase/decrease iv 1 per use (like carbos , protein , etc. but increase/decrease iv instead) sell on shop or game corner price
wind weather move (we're already have fire/earth/water and ice, so why not wind?) name: Extreme Wind , pp 5/5 , flying type - get rid all entry hazard (Spikes , Stealth Rock , Toxic Spikes) on the battlefield and prevents it from set - increase flying type speed by 50% - increase special base-flying type move's power by 50%
I always thought a nightfall weather would be cool
Night Falls (you can probably think of a better name) -5 PP -Summon night for 5 turns -Moonlight recovers 50% of max HP -Dark and Ghost type moves have 100% accuracy (I don't think that's too unbalanced as there aren't a whole lot of insanely overpowered ghost or dark attacks) -Dark and Ghost type Pokemon bypass entry hazards until weather effect is over -Fire and electric moves have accuracy cut in half
I'm not a fan of perma-weather abilities, so I'm not suggesting a perma ability and Pokemon
One thing I thought would be cool (before Gen IV) was starting in Kanto. When you beat theE4, you either have the choice to go to Johto (via waterfall HM) or Hoenn (via Fly HM). And there would be region exclusives. So, maybe you can have branching continent exploration.
