Very nice indeed! I need some fanning powder though always very expensive online!
Have you tried a very fine baby powder? Leave a bottle of the stuff, slightly opened, in a place where it will not be disturbed and will be exposed to heat (a radiator in winter, a sun-filled window, etc.) This will desiccate the powder, but you must be careful when handling it - this fine dust, if it's spilled and gets into the air, it could literally make the air flammable like a fuel-air bomb. (It's why silos occasionally explode and why you have to clean the lint trap in your dryer - a flammable particulate gets into the air in a concentration high enough to cause it to burst into flames when exposed to a fire or a spark, thus turning all that air and all that particulate into a giant ball of flames in one rapid, explosive burst.)
Back to the point, once you have a fine powder with little to no moisture in it, try using that in the same way that you would use fanning powder.
Another alternative would be to "soap" your deck. Using a solid bar of completely dry, inexpensive soap, draw an "X" from corner to corner on the face and back of each card, then shuffle several times. You can turn an absolute crap deck into something that functions more like a deck should.
