Paul Gordon's Killer OMG is a wonderful effect. In my opinion it has all the qualities of a great magic effect including several surprising moments and it resets instantly for walk around performances.

I have used similar packet tricks before where a small packet of cards turn over one at a time and then the backs change however these effects usually rely on doing a "flustration count" repeatedly or having an extra card that you have to ditch at the end of the effect so that the cards may be examined. This trick has been well thought out with natural moves and cards that may be examined at the conclusion of the effect.

I am very pleased to tell you that I have already used this effect at a paid gig and can see myself continuing to use it a lot. I may even order a spare set!

Thanks Penguin for carrying Killer OMG and thanks to creator Paul Gordon for a great card effect.
