Clefable or Sylveon for sword in-game team?

I am currently using 9 Pokémon in rotation to play through sword, but it feels like I need a fairy type. I looked at all of the options and narrowed it down to Clefable and Sylveon. But which should I use? My team is:

Which of Sylveon and Clefable should I use? Please provide a reason and preferably a moveset. Also, tips and changes to the rest of the team are appreciated. ;)

Clefable has the slight edge.

I recommend Clefable as it has a better movepool. Sylveon is mainly used for competitive use due to its Hyper Voice and Pixilate Combo that can deal great damage. Though Clefable is in the OU tier, it can still be used for in-game playthroughs.

About the sets, for Clefable I would use this:

ClefableAbility: Magic GuardNature : you chooseIVs: You choose- Flamethrower- Moonblast- Soft-Boiled- Calm Mind/Ice Beam.

Competitive use:

Clefable @ LeftoversAbility: Magic GuardEVs: 252 HP / 4 Atk / 252 SpDSassy Nature- Knock Off- Moonblast- Soft-Boiled- Stealth Rock

Hope I helped!
