....allright... I've been testing Shuppet for a bit now and I regret to inform ye all that it's likely the worst of the LC Ghosts. :\ It's a total contradiction, unfortunately; it has a great Attack stat, but a nonexistent physical movepool; great support movepool, but poor defenses and speed (you gotta have one or the other to use Support stuff, and poor Shuppet has neither -.-).
I encourage others to do some testing with Shuppet too, it's entirely possible that you won't get the poor results that I have, but... that's my impression so far. :0
