Deadly Shurikens is a killstreak used by Ninja class.
Requires 3 kills to activate.
On activation, the Ninja gets equipped with 3 high damage Shurikens. They also Poison enemies.
Shurikens equipped with burst module make all 3 stars fly at once.
Be careful. If you activate this killstreak while reloading, you won't be able to fire them and you will have to wait until you get killed to get back to your weapon again. Same happens with Betsy.
