Can banshees power , it's going to get loud in here, shut down trait ' can use' powers that grant use of super senses impervious or the likes.

My guess is can't use wins.

Yep. Agreed.

Please quote the power

IT'S GOING TO GET A LITTLE LOUD: Opposing characters within 6 squares can't use Super Senses. Opposing characters within 6 squares can't use Impervious, Invincible, or Invulnerability but can use Toughness instead. When Banshee hits a character that can't use a power due to this trait, increase damage dealt to that character by 1.

If it only affected characters that had the powers on dial it would say 'possessed'. Powers granted by SP or trait are, by default, 'can use' type powers

Yup, this.
