Lol this sounds funny, but on a serious note, if voodoo is really real then this is possible for those that can do it ::)but since I don't believe in it as I have only seen this on TV I will say this is not possible.
If this is for real then I don't want someone to try this on me or while I'm playing.
I don't want to believe with this too but if there are gamblers who think that this is effective. I think there will be some testimonials and will say that this has been effective on their side. But until now, I haven't heard any or probably they chose to remain silent.
