Clonezor/Shadow Entity

Shapechanger. The shadow entity can use its action to polymorph into a Small or Medium humanoid it has seen or back into its true form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Assassinate. During its first turn in combat, the shadow entity has advantage on attack rolls against any creature that hasn't taken a turn. Any hit the entity scores against a surprised creature is a critical hit.

Evasion. If the shadow entity is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage on a successful save.

Sneak Attack (1/Turn). The shadow entity deals an extra 7 (2d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the shadow entity that isn't incapacitated and the shadow entity doesn't have disadvantage on the roll

Phasing (Recharge 6). The shadow entity can pass through walls and other solid barriers. It can move through a solid object as if it were difficult terrain. If it ends its turn inside an object, it takes 10 (3d6) force damage, and it is shunted to the nearest unoccupied space it can occupy.
