You could buy a normal blank face deck from Bicycle and an Artisan deck. There are tutorials online about splitting cards; it takes some time to get used to it, so practice on a deck you no longer use. Once you have the skill, you just need some time to complete a full deck from two decks.
A simpler idea would be to simply glue the blank faces onto Artisan faces, but this would result in very thick playing cards. This can work if you only need a few gimmick cards, which are not examinable anyway. Don’t worry visually nobody would get it.
Alternatively, you can try removing the color from the cards yourself. For example, you could use nail polish remover, acetone, universal thinner (nitro thinner), or paint and varnish removers commonly available at hardware stores. This way, you can remove the color from the cards yourself and end up with a blank face decks.
I’ve used all of the methods above to make my own gimmicks. All of them require some level of skill, so practice on older decks out don’t use anymore first, but I wouldn’t say they’re difficult. Each method also has its own pros and cons. The cards won’t look like a brand new deck afterwards in any of the cases but nobody will notice, cards used by hands of a non magician generally look beaten up or used anyway.
You can use some fanning powder available at almost any magic dealer to regive them some slide.
