Baton Pass is fine to talk about. However, passing defense boosts tends to be rather weak since while accruing enough Defense boosts can make a Pokémon unkillable, still vulnerable to Special Attacks, crits, and phazing. That being said, Dubwool also gets Swords Dance, which that is a potent Baton Pass option. And really that's all Dubwool has going for it outside of Cotton Guard Body Press shenanigans. The Normal type has been getting weaker with each generation with the rise of Steel types, and just how common Ghost types are. This generation has been particularly cruel for Normal types, removing their favored STAB in Return. And while Dubwool's defenses are above average, without any resistances, and no reliable recovery, Dubwool gets worn down quickly.

Baton Pass set. Ideally Dubwool will be able to Sub down to get the Salac boost as well as get a Swords Dance somewhere along the way before passing on to a physical sweeper better able to capitalize on the boosts. Double Edge to prevent Dubwool from being Taunt bait.
