Personally I love this Pokemon all of its stats compensate for it's incredibly low speed my lv73 has 226hp 242atk 199def 115spatk 199spdef and a whopping 60spd. I think this will be an incredible mon but I see absolutely nobody use it.
Escavalier is really good yet it lacks speed and special attack. If you want to fix it then put a trick room set up which makes slow Pokemon move first. It is pretty cool and it makes them better. Then you can have a sweeper. IF you use this setup then you won't need a choice scarf.
Escavalier: choice band
Evs: 252 hp 252 atk 4 sp def
