maybe an electric type? jolteon/raikou/zapdos are all solid choices... raikou is the best imo, but i'm against legendaries so i would use jolteon. noteworthy moves include thunderbolt, thunder wave, hp (ice/water/grass), substitute, baton pass, and wish. even electabuzz could work, with something like thunderbolt, fire punch, ice punch, and cross chop/psychic.
another great option is gengar. he is incredibly versatile and can fill physical and special sweeping roles, can be an annoyer (though is best as a sweeper imo) and is just plain cool. thunderbolt, psychic, confuse ray, shadow ball, destiny bond, grudge, w-o-w, sub/punch, snatch, taunt, the list can keep going depending on what you need him to do.
plenty of other good guys exist, but you have some of the better ones on your teams already and based on the fact that none of them have legendaries, id say you're trying to avoid them, to which i would also say good job on not selling out.
