If you can find it, you might consider giving Matting Solution a go. I use it in French polish to get rid of the shine. It's a suspension of a very fine pumice in a VERY hard modified shellac polish. I experimented on some decks yesterday and have had great fun thinking up different ways to use it.
It needs to be applied by hand using a cloth (mutton cloth is best) rolled up into a small wad. It has a milky appearance is odourless and dries completely colourless in about 20 mins.
If you want to experiment for yourself you can get it here if you live in the UK.

It's called MATT POLISH ADDITIVE. Or goes by the name of MATTING SOLUTION.
LT12 is their stock number. I buy it by the gallon, but it's about £10.00 for ½ a Litre, which should last you many years or many decks. Shake the bottle well.
With a bit of thought, I've got a deck that shows different cards depending on which direction you spread the deck.
It works and is very durable.
