well since GF let pokemon have Hidden abilitys then why not let pokemon have a hidden type as well..... and get it from the dreamworld also
for example: Charizard is FIRE/FLYING go to the dream world and he can get his hidden type which would/could be FIRE/DRAGON.
i mean not all pokemon would have a hidden type jus like not all pokemon have a hidden ability.
GF should do this or somthing like this
i mean ik only a good select few of pokemon would be able to do that....but its those pokemon that can.....
