If it actually works well, then perhaps. otherwise, it seems more trouble than it's worth, and that's coming from some who can't shuffle for !@#$. Perhaps for RftG where shuffles through the deck of 100 cards often?
I prefer sleeves. I know people are outspoken on the expense vs just buying another copy, but I have to say that when you have 15-20 cards or less in your deck the extra thickness the sleeves add makes them easier to handle.
