for that set, probs, unless you have somefin else setting up the move
the best ones that don't require tutors include celebi, chansey, granbull, roserade, shaymin, florges, and aromatisse...when the heal bell tutors arrive, sylveon, vaporeon, mew, umbreon, mega gardevoir, togekiss and a few others are also pretty good. full lists are here and here.
stunfisk's typing lends itself to beating both...though, it is weak to more common special moves (ice beam, giga drain, surf, etc) than physical moves (earthquake), so I guess going physically defensive might be best
