Cannot be Special Summoned. During the End Phase of the turn this card is Normal Summoned or flipped face-up: Return it to the hand. When this card is Normal Summoned or flipped face-up: Target 1 face-up monster on the field; change that target to face-down Defense Position.
Wanted to bring this card to your attention. It's simple and effective.
Stops Fire Fists from using their battle tricks and prevents Rabbit from grinding
into Zars. It also stops the Agent floaters ,namely Thunder King and Venus, meaning
you will have recources left to handle their boss monsters. Tsuk also shines in random rogue matchups like Samurai , since it allows you to handle Shi En much easier and single-handedly pushes through Kizan,Grandmaster and Enishi.
Card is really solid right now and defnitely worth a spot in the side deck, if not main deck.(in decks like Wind-Up or Prophecy.)
