Twilight

{1}{w}{u}: Exile target creature until end of turn. Twilight becomes a copy of that creature until it returns to the battlefield.
Everyone has a part of themselves they don't show to
anyone else. Not to friends, not to lovers, not even to
family. With fake smiles and bluffs, they hide their
true thoughts, their true self. This is how the world
glosses things over for a fragile peace.
