>>29778103He's not terrible, he's just not great.
Stat wise, he's solid. 120/80/60 defenses may seem meh, but he's basically a slightly bulkier Mamoswine with a slightly less shit defensive typing. 125 Atk is nothing to sneeze at either.
Typing-wise, he's wishing he had it better. It's not great defensively, but at least he gets an immunity to come in on.
Ability-wise, Fluffy is pretty nice. Not amazing, but decent. Definitely ups his longetivity.
Move-wise, Hammer Arm and Shadow Claw are decent and give him unresisted type coverage. So that means that he gets to choose between a Pain Split + Bulk Up / Substitute set, or a Sword Dance + Rock Slide / (Dragon Claw) set. He'll be able to run a Life Orb set, a Leftovers set, and a Band set - too slow for Scarf though.
Overall, he's a pretty solid Pokemon that can come into the battle really easily thanks to his immunity and Fluffy, and he can stay there for a bit and do a bit of damage, but he really wishes he was Ghost/Fighting instead of Normal/Fighting (which would make more sense as it's a spirit living in a fucking stuffed bear).
