Under Discussion.
And a quick discussion at that. You can't say we NEVER have those.
So, the answer is "no".
The Arcane Cloak's unit's cards' immunity to targeting persists while there is another legal target for the action. Even if that other legal target was ALREADY targeted by an action that can target (or requires targeting) multiple targets, it doesn't change the condition of the immunity. There is still a legal target in the army, so the Arcane's Cloak's units' card's can't be.
