[CRUEL KILLER]
Valid:
When this Ninja is removed from play by the effect of your opponent's Ninjas or Jutsu cards, you can select and discard 1 of your other Ninjas in this Ninja's Team instead. In that case, this Ninja cannot be removed from play by the effect of your opponent's Ninjas or Jutsu cards during the turn.
"When we finally fight... it won't be to advance to the next stage, but solely for survival. One seeking to destroy the other."
