You might want to slash Poison Heal on that set, since it gives an effective immunity to spore (+other status) and also better recovery than leftovers. The one-turn of status vulnerability means you need a free switch though. Otherwise, that's a pretty good Imposter lure that most people won't expect (yet...). Unfortunately it doesn't look like it makes much of a dent in bulky Steel types (and coverage for that would invalidate its use against Imposter).
