The ninja assasin would specialize in attacking clan castle troops it would be able jump walls it could be low hit point low cost low capacity low damage or high cost high hit point high capacity high damage whatever the community prefer or we could vote if they think the character would enhance the game and given serious consideration it would give the option of air or ground troop attacks yousing ninja stars for air selection and of course a sword for ground troops. It should be available in your dark elixer troop trainer and available at level 1. These would be awesome for offense and would help on defense as well.
