Mystique character concept

Mystiques ult would be similar to winter soldiers, they'd preform a attack on a target dealing significant damage, if the enemy dies the enemy team will not be alerted to the death, Mystique would take the place of the player they killed and would be able to preform the ult again. Her primary fire would be dual pistols having a damage fall off in damage the further away she is from a player Her secondary would be a movement based ability similar to iron fist Her melee would be a pocket knife Her passive would be looking like a different member of her own team
