Magic Tricks

No they aren't all examinable but you can hand out the blank cards if you prefer. It doesn't really make a difference though because if you perform the trick properly nobody will want to examine all the cards. They can clearly see their named card is the only printed card. There are so many impossible magic moments in this routine that build your credibility!

I perform this a lot, for over 10 years.
It doesn't require a lot of sleight of hand, but it requires some people/ card management.
It fits me, it could not be your kind of trick.
It fits me that not all the cards are examinable, because this is a short piece of theatre. Not boring theatre, but it requires some level of concentration from the audience.
I do this often on the spectators flat hand, so that I put the dirty card first, different back up, and then I put the blanc cards face up on top of that card.

If you still don't have this effect, get it. They can pick any suit and any card. It is designed to give the illusion that the spectator makes all the (correct) decisions. No one ever asks to examine the cards. The only thing you can't do is repeat it. But if the spectator believes they are regular cards, then it would be impossible to repeat -- so they don't ask you to.

You are as clean as your skill level allows you to be. This isn't real magic where the cards do all the work and can be handed out, nor should they be because then you are not doing magic you are just doing puzzles and challenging your audience to figure them out.
