What is the most effective, fastest and least damaging way of shuffling sleeved cards? What's more damaging, riffle or mash? I riffle corners and try not to bend the cards. I found out hindu/overhand doesn't mix the cards properly. Thanks for your help!
I put the cards in seven piles, then riffle/mash shuffle them, then riffle/mash them seven or eight more times, taking the top and bottom twenty or so and mashing them into the middle a few times during the process.
If i'm shuffling a limited 40 card deck, I just riffle shuffle. They'll last the few games I'll play before sleeving them.
8 or 9 riffles. If you are careful, and just riffle the corners/edges, you shouldn't damage your cards at all. That crap where people try to emulate what they see in movies? Yeah, that damages the hell out of cards. Normal decks of playing cards are cheap, even a deck of nothing but commons will get expensive after a while to keep in shape if you make a habit of that.
