[ShiningCharizard]

ok,as i understand it,when you use LNS,you must choose 3 different types (colors?) of pokemon.so,im wondering,can i LNS for say,a dark pokemon,and a grass/dark pokemon (like team aqua's cacnea?) or a psycic pokemon,steel pokemon and the steel/psy version of jirachi?

thanks alot.
