>>43817816+30 into Def stat so Fur coat makes it actually viable as a defensive wall.
+Add stat changing moves to the pool (Swords Dance, Hone claws, Agillity)
+Give Furfrou more options to utilize its defensive role (such as slack off and refresh).
+give it the ability Baton Pass for team synergy.
Optional:
Furfrou seems like a pokemon that would benefit as a Normal/Fairy type. its hair cutting lore and stylish colour is very similar to that cosplaying gym leader. It would also give more credence to the defensive wall role in its ability.
