The rules of the 2010 VGC state:
This obviously means that Pokémon with "illegal" moves gotten through the Ditto glitch are banned, even though they are possible without hacking. However, does this mean that you could use the Ditto glitch to obtain a Pokémon with an "illegal" combination of legal moves, such as Belly Drum + Aqua Jet Azumarill or Follow Me + Cross Chop Electivire (just examples), and it would be allowed?
Pokémon may only use moves (including those learned in an earlier video game) that have been learned through one of the following methods:
- By leveling up
- By TM or HM
- As an Egg move, through breeding
- From a Move Tutor
- Already learned by a Pokémon that was received at an official Pokémon event or promotion
- Already learned by a Pokémon that was received from another Pokémon game (such as the Pikachu that knows Surf from Pokémon Battle Revolution)
- By Smeargle's "Sketch" move (limited to the above moves learned by Pokémon from 001 to 493)
