One would think this would be an easy one. Sadly it is not because there is no 'one' answer and it depends on exactly what you are doing.
For examples:
If you are in an ID situation then roughing fluid is best.
If however you are looking to place a double on the table then I suggest using nothing but skill. Learn to place a double on the table as one card. It is not easy and there is a knack and you have to practice on different surfaces but I do it all the time without the cards seperating. And I am practicing all the time. It is rare for me to pick up a deck of cards and not place doubles on a surface, my co workers look at me like I'm crazy sitting around at lunch placing a card on the table only to pick it up, shuffle and then place another on the table. Little do they know it is two cards. Little do they know it is part of one of my favourite effects and I've shown it to most of them many times.
If you really need the cards to stick then there are several options. Magicians wax has proven itself to be a magicians favourite, (I don't like it). There is an adhesive artists use to position work and re-position work. Those usually work well just make sure it is non permanent. I know another magician who swears by gorilla snot, not to be confused with gorilla glue. Use the glue and you will never seperate the cards. Gorilla snot will just make it tacky. And no gorilla's are harmed in the making.
I've even seen double sided tape work well. Just make it taky and yes it will have to be replaced.
Let us know what you find.
