Mathematical card tricks

Question

For quite some time I have taken interest in analyzing card tricks that make use of a deep knowledge of advanced mathematics and there's been some progress. However, all the tricks I've tried decoding seem to be based on elementary math which any serious high school number aficionado can understand and appreciate if not decipher. Is there a card trick that's so outlandishly brilliant that mathematicians need to wreck their heads over it? P.S: I'm after the holy grail of card tricks that require minimal sleight of hand
