Deputy of Detention

• WWizards of the Coast2019-01-25
  Official Ruling
  This ability has only one target. The other permanents with that name aren't targeted. For example, a permanent with hexproof will be exiled if it has the same name as the target nonland permanent.

  Official Ruling
  A face-down creature has no name, so it can't share a name with anything. This includes other creatures with no name.

  Official Ruling
  Unless a token is a copy of another permanent or was explicitly given a name by the effect that created it, its name is the subtypes it was given when it was created plus the word "Token." For example, if an effect creates a 1/1 Soldier creature token, that token is named "Soldier Token."
