Hi all,
I'm soon to perform an effect merged from two others: effect from Andrew Mayne's "Mind FX", working from "The Unexpected" from Marc Spelmann and Peter Nardi. It's a fairly basic prediction and force, the fun part being that the prediction is a vital organ on ice in a box! Mayne suggests using a rubber organ, I intend to just go down the butchers

I don't really like using the gimmicked deck suggested though - not examinable enough. So I've decided to use the patio force explained in The Unexpected, although I think they said it's originally Nyman's? Or someone's, not sure.
Get to the point: I can't decide whether to use totally blank cards or blank faced cards for the names of the organs. I have to be able to find one card (the force, funnily enough). Blank backs would require a nail nick, whereas I think normal bicycle backs would be more examinable as you could use a basically un-findable mark such as etching a single extra butterfly.
However, would a playing card design suggest too much trickery? Or be more open to accusations of marking?
I know we get a lot of "silly" polls on here, sorry to waste your time, but I'm really undecided about which to use and have decided to let TM be the judge!
Thanks for your help.
