Shaco double Guardian Angel [GAMEPLAY]

He basically went invisible as i killed him and i q'd around to make sure he wasn't trying to sneak me, i saw the GA revive animation but he also still had the swirly white things around him, he went into fog and then came back without those swirly white things.. watching the replay i don't see what i saw ingame but i know 100% it looked like he had double GA and it lost me the game.
