So Darkrai, Latios, Entei, Lucario, since I'm assuming this guy understands the importance of team composition he likely has Pokemon to deal with Ground-Types since Entei & Lucario are weak to them, so perhaps something like Salamence would fit that, to round off his team to minimize dealing with a bad type to type situation a Skarmory would minimize it such that the only type he'd remotely have trouble with would be Rock-Type in that Salamence & Entei are weak to it and only Lucario has a Resistance to it.
