Effect:
Select 1 Ninja card from your hand, place it in your Village keeping it face down, and declare if that Ninja card has 1 or more Hand cost or not. Then, your opponent guesses if that's correct or not and then reveal that card. If your opponent guessed it correct, place that card in their Battle Reward area faced down. If not, put that Ninja card in play.
