Review
There is a video available to watch here :

The video explains it better than I ever could but I will have a try regardless.
You open a deck of bikes, you can get either a red bike box or a blue one, lets say you get blue.
You open the deck and slide out the cards, only to find you have the wrong cards in the box, you have a red deck.
Oh dear silly you, lol. With a snap of the fingers or in the blink of an eye the deck turns blue as you completely remove the deck.
You then spread the cards face up and ask the spectator to pick any card, or you can ask them to just name a card without looking at them first.
You then place that card on the table and dribble the cards into your hand showing they all have the same colour back.
You then turn over the card on the table to show it has a different colour back.
That is the basic trick though obviously with that there is room to craft a nice story around it.
Overall
I find people really like this trick, you get a few colour changes into the routine and the choice of colour can change, they can all be blue backed with a chosen red card or all red with a chosen blue card.
It has no rough and smooth, no complicated sleights, the most complicated move is to cut the deck and is totaly self working with an instant reset.
I am really quite fond of this one and if you are after an easy, good deck effect that you will be able to do virtualy as soon as you open it, then this one is for you.
I am not that good at describing how the trick looks but if you watch the video you will know if this one is for you.
It is worth noting that you will not then be able to use the deck to do other normal effects as it is gimmicked, so this is a one trick pony but a good one.
Also worth note is that it is not examinable, but not much of these easy to do wonders are so don't let that put you off.
A quality trick, very well made and easy to achieve a strong reaction.
I give this 8 out of 10, losing a point for each of the last two points I made.
Hope that helps,
