As lame as magic is, it does work.

It gets attention, buying temperature and interest in you, its one of the millions of gay things you can do with girls that we all know is lame but girls lap it up.

Don't have a deck of cards with as thats too gay but knowing a few tricks then you can use it as a reason to go back to yours PLUS its novelty can sway her away from enjoying the rest of the night or friends etc.

Same with palm reading and the cube, its all gay and blatant lies but girls are stupid enough to believe it. Most girls believe in palm reading, astrology and all that shit.
