So if you could give a "move" to a Pokemon what would it be?

Pound to Snorlax. It works wonders with my Wigglytuff (which in my opinion is a poorman's Snorlax)

Psycho Cut to Exeggutor. Psycho Cut/Solar Beam or Psycho Cut/Psychic would be amazing for offense.

Super Fang to Raticate aka defending pokemon loses 1/2 its current HP. :-D

That'd be super broken though... what I'd actually really like is adding this move to Clefairy and Clefable, replacing Pound.

Name: Fairy Wind
Type: Fairy
Damage: 6
Energy Per Use: 7
Cooldown: 0.5

Basically it is a Fairy version of Water Gun/Bite/Scratch/Dragon Breath. It would make Clefable a pretty good answer to Dragonite if you happen to live in a place with zero ice types. (like me)

Low kick and rock smash to machamp, make him much more potent.

Definitely agree with pound to snorlax, and I would give back dragon breath to gyarados, or at least give him water gun

Rock throw to Omastar

give more water type moves to kingler and give back acid to weezing and fairy moves to mr mime. Focus blast could be great for machamp.

I agree with all these.

Also, I'd give Pinsir at least one good move, either Bug Bite for a fast move or Bug Buzz for a charge. With even one of those he'd be useful against Exeggutor, but his current "best" set of Fury Cutter/X-Scissor just doesn't cut it.

-Fire Fang for Flareon and Charizard
-Vine Whip for Victreebel and Vileplume
-Psycho Cut for Exeggutor and Hypno
-Spark for Jolteon
-Low Kick for Machamp
-Mud Shot for Rhydon and Golem
-Bug Bite and Megahorn for Pinsir
