Haha, sorry. He looks so much like a dragon. A ghost type. And the OU tier you said is to deal a lot of status conditions? Would Jellicent be a good addition ? Or would that be a bad idea because its part water?
And what kind of role does Sylveon play? I've read so many different ones and I cant tell which one would work best
Jellicent is a good option because it resists steel and can burn physical attackers with will-o-wisp or scald.
Sylveon has two big roles that you can choose from: Bulky special sweeper and cleric.
The bulky special sweeper hits very hard with its base 117 STAB move Hyper Voice and hits Poison types that resist Hyper voice hard with Psyshock. The other moves are usually shadow ball and a hidden power.
The cleric is used to heal itself and its team mates by using wish, heal bell, protect, and hypervoice. If you're playing on cartridge, this Sylveon is harder to use, as some of the moves need pokebank to be used.
The fully offensive Sylveon is often outclassed by Mega Gardevoir, but if you're already using a mega Sylveon is a good alternative.
PS: I don't mean to sound harsh, but could you not double post? If you have two things to say, put them in one post instead of posting twice. It bothers a lot of people, not necessarily me, and I just wanted to warn you before others did :)
