I think by now you all must know how much I adore Rob's effects and craftmanship. With Slither, he has outdone himself! This has to be the finest gimmicked card I have ever seen! There are plenty of effects possible with this great gimmick, here is just one: You display four cards, two red queens & two black nines. The queens are given to your spectator to hold. You now show that you are truly holding the nines but within a blink of the eye the four card schange places! This fantastic card does all the hard work for you! Another great trick you will not want to be with out!
