That certainly is a different type of moveset. Very interesting... I think I may want a little extra oomf in my attacks, so may use a Modest Nature instead(since I will be using Hyper voice.) Calm mind plus draining kiss is actually a decent combo for healing.
Though... maybe Heal Bell is not needed? I don't know. I may test my Set with Heal bell and Wish with Hyper voice and Psyshock/Shadow ball at first, just to see, but may switch to a Calm mind set later.
Yeah I doubt Sylveon would ever want to stay in on a metagross.
Seems like a bunch of people like Bold.. Does a Bold nature with Full HP and Def EV's really add up? Don't you further want to boost that monsterous SpD, or is the HP enough for that? I mean, I have time to decide... but I wonder if I want more power of more survivability... I was thinking, if i did my Heal Bell, Wish, Hyper Voice, Shadow ball/Psyshock, I would use a modest and go 252 in SpA and rest in H and SpD to make her a Special Wall+ cleric, just like my Florges is on my current X team. She takes special hits like a champ, but physical hits bring her down quickly...
