Training the Togepi will be all up to you. A lot of people have used it and as a Togetic/Togekiss it can come in very helpful on your team. Most try to obtain a Shiny Stone so they can evolve Togepi all the way to a Togekiss as it's much stronger. So, if you wish to use it, then I say go for it. You never really know how good a Pokémon might be in-game until you try it.
