Even the best stop thinking too soon
Mathieu Bich TnR effect is crap on several points. Firstly, I don't know how he presents the effect, but to see the convoluted presentation by Kenner with choosing a prediction, tearing it up then having another card selected, etc - made no sense at all.
The piece by piece "restorations" were not square _ in other words, they looked like they were being adhered with clear tape and not square like an actual restoration would look.
Secondly, Bich obviously never read and studied Our Magic by Maskelyne and Devant. And rule number four in Chapter 3: Unity states:
"(4) Never produce two simultaneous effects, and let no effect be obscured by any subsidiary distraction."
In other words, do NOT cloud one effect with another so close together. You tear up a card for no reason, restore it, then change it to another card??? The change at the end convolutes the crappy restoration just executed.
