Debuff? Not really- when units come with their status nullifying abilities, it only applies to your team. You aren't able to entirely debuff an opponet, but it's possible to give them status ailments or some of the other newer types such as 'attack down' or 'defense down' to partially nullify it. I believe that Ardin and Fiora have those, among others.
