magic tricks

Hi It might surprise you to know that I actually do magic tricks with cards. I was thinking of doing some card magic to japanese people on the plane so I can make the people on the plane happy. I want to say, "remember this card, it is your card". do i say: "kono card wa oboite imasu, anata card des." I have a feeling that "oboite imasu" is not right. How do I say "take this card" is it: "kono card wa totte des". "is this your card?" "kono card wa so des ka?"

Konnichiwa! I'm sure playing card tricks - *toranppu toriku / torannpu majiku* - on the plane would be a great way to meet Japanese people!!! :idea: _Remember this card, it is your card._ *Kore wa anata no kaado desu. Oboete ite kudasai. * :idea: _Take this card_ *Kono kaado o totte kudasai.* :idea: _Is this your card?_ *Kore wa anata no kaado desuka?*
