Video shows Faceless Manipulator on a Silenced Mal'Ganis, causing stats to buff then unbuff twice in quick succession, healing minions due to quirks of the health system.
Tested and confirmed with Stormwind Champion. However it only affects transforming into a copy, not summoning a Silenced copy via a card like Unsleeping Soul:
(Casting Unsleeping Soul on a Champion.)
(No consequence besides a normal removal of the aura. Brann's health stays at 3.)
(Using Faceless Manipulator on the now Silenced Champion.)
