The "Shadow/Dark Skelleton" [1Large]

First of all, thank you for reading my idea and sorry for my bad english. This is only a raw idea
So, the "Shadow/Dark Skelleton" can change defense buildings so that the defending building does not focus on the "Shadow / Dark Skellet" but a random other troop within the range of the defending building (as long as there are other troops except the "Shadow / Dark Skellet"). He attacks on a single target on close range at the ground.
I think that a new single troup is refreshing, especially since it is a dark groundtroop and there is no comparable dark group in the dark rows.
I have no special idea how to ballance the troop, so i think SPEED, ATTACKSPEED, HITPOINTS, DAMAGE, COSTS, TRAINING TIME, FAVORITE TARGET (defense buildings/any), and if the defense buildings (change by being hit by the "Shadow/Dark Skelleton" [for limited time (mabey change the target random all 10s) or not] or if this ability is permanently for all defensive buildings) is adaptable.
He looks like an dark skelleton, (mabey a little bit bigger or smaller with a bit of details)
