Hey everyone :)
As nearly all players know, ghost types have a big advantage for training in this game, because they are not effected by a few moves of the opponent and we can't pick between a lot pokemon to train on, if we want the highest exp. The only problem is, there are not many cool ghost types. I like to have cool pokemon in my team, but only 2 of them are ghost typed.

I was enquiring, if there were items or moves in the pokemon games, which change your pokemon's type, because I didn't remember clearly. Thanks to SpikYyY43 and poke might for the help.
Arceus changes his type depending on the plate he has, and there are already a few moves, which change your pokemon's type, like
Conversion, Conversion 2, Mirror Type, MultiType.

I think it would be very cool if there was an item or a option, that you use on your pokemon once, which changes your pokemon's type, to either ghost, or any type you would like to pick. I would rather suggest only Ghost, so it can be either it's original type or a ghost type. Or I would also like to make it a ghost / ground type, because this type has the most advantages against a Mew / zapdos. That's the creators choice :P

I know people would say, "but then your pokemon would have advantages and make training easier!" But actually, it doesn't matter a lot if you either have a team of golurks, or a team of cool pokes, whose type's changed to a ghost type. It would make your training team look much cooler :)

I appreciate any comment about this, negative or positive, just state your opinion. Thanks :)

P.s. I would prefer an Option, because I wouldnt want to remove the exp locks on my lvl 10ks
