For card effects (i don´t like the term trick) i would say :
Back in Time Triumph by Jay Sankey
Let me explain why :
It´s simple in its premise,easy to understand and really impossible for the spectator in terms of what happend.
And last but not least the kicker at the end - is in the spectators hand.
It is always hard to open up a magic presentation with a card effect,
you fight agains various pre-opinions.Some people hate card effects....counting tricks etc.
That´s why you have to set a premise before you take out your cards.
And the plot in "Back in Time" is a interessting theme.
If you think about it,everyone had the wish to go back in time and change things up.
I will give you my patter :
"Hey who of you guys believe in time travelling?"
Something like in the movie Back to the future,would´t it be interessting to go back in time and have a cup of tea with
Albert Einstein or see the dinosaurs live in action?Or changing the stock price at the Wall Street! Don´t you agree?
Well,i´m not able to go that far back in time,i´m working on that part but for now i´m only able to go back in time for 1 minute.
Let´s do a time travelling experiment - who´s gonna particpate? You? Great.
Look i´ve got here a deck of cards.
I want you to pick any of those,it doesnt matter which one.
Look at the card,show it to your friends and if you don´t have friends...well then just remember it.
Place it back in the deck and don´t forget the card! If you do...then your and my time is wasted.
Now look,i´m gonna mix up the cards in very different way then most people do.
The cards are going face up and face down....a way like a little child would shuffle cards up.
As you can see the cards are in chaos like state.Knowing your card or even finding your card would be impossible.
"Looking at the top card" Your card wasn´t the 6 of clubs or?
Great,else this experiement was over and not impressive at all.
Well,take this 6 and wave it over the deck like a magic wand.
STOP!
Do you know what you did right now?
You have send all the cards 1 minute back in time!
Yeah really!
Look all the cards are now straightend out like in the beginning of this experiment!
And we are back in time right at the moment where you have picked your card! Turn the card in your hand over!As you can see,this script/patter is simple but creates in the mind of the spectator interesst on what you are going to do.
Also everyone can rely on the thought going back in time.
So think about your effects which you perform and how you can connect to your audience by shifting the patter to be interessting.
Sucking them into your magical presentation like a Vortex (shamless plug i know).
After the effect is over you can let them sign the card and go into a ACR make it come back to the top (like going back in time).
For me my effects should be like : If i could do really magic - would i perform a cutting to the aces effect? NO!
Here is a link to a Video which shows only the reactions of my magic
Enjoy!
