Tempest Stealth Rogue, Fuuki

:[ 1 & Put this unit into your soul] If you have a Nubatama vanguard, and the number of cards in your opponent's hand is three or more, you may pay the cost. If you do, choose a card at random from your opponent's hand, bind it face down, and at the end of that turn, your opponent puts that card bound by this effect into his or her hand.
