Activate this card by Tributing 1 face-up "Ninja" monster; Special Summon 1 Beast, Winged Beast, or Insect-Type monster from your hand or Deck whose Level is less than or equal to the Level the Tributed monster had on the field +3. When this card leaves the field, destroy that monster.
To elaborate on what I said; there's no way in hell this card is a 6.5 out of 10 when you give fucking XYZ Dragon Cannon (one of the hardest monsters to drop on field) a fucking 7. The guy that gives the scores should try to git gud.
How is this a 6.5 at all? Tribute Lady Ninja Yae for this, special summon Red Dragon Ninja, banish Yae, get rid of something your opponent has facedown. You can use Red Dragon Ninja to summon more Red Dragon Ninjas or Nepthys and other powerful monsters.
