New dark elixir troop: ninja

Okay first troop idea here, so here goes.
The ninja born from the shadows, a master of skill. The dark elixir drunk by this troop gave him extra smarts and strength allowing him to preform 2 types of attack: melee and ranged(at a decreased damage). When there is a building/defense nearby not covered by wall he does a devastating melee attack with his katana, however if there is none others near by except behind walls he throws shurikens but at a lower damage. And his coupe de grâce when near death he does a feign death, or fakes his death, and is invisible for 3 seconds(max time) and the defense no longer is targeting him. He cannot attack during those 3 seconds
