So you may be pretty handy and fancy with shuffling the cards.  That’s great.  Unfortunately not everyone is as good as you, so that means they sift the cards willy-nilly hoping for some semblance of randomness when all they’ve done is move the previous pattern around, so that you and the others see the same cards show up in the next hand of Texas Holdem.  That is not good.  In fact, it’s a wasted hand, and a wasted ante.  Because when people generally have a better idea of what the patterns are based on the cards revealed during play, they may either bet on that or just fold rather than be a sucker to someone else’s knowledge.  That’s real money being lost.  What’s more, there’s time.  Folks that can’t shuffle cards too well might take a lot of time doing it.  Even if you’ve got a full-time dealer you want to go from hand to hand quickly whether he’s good at shuffling or not.  Mechanical card shufflers will handle the job for you quickly and easily, throwing in enough randomization to throw off the patterns made from the previous hand.  There are lots of card shufflers for various kinds of games, but a standard Texas Holdem Card Shuffler is perfect for any poker game, doing the job quick and easy.  Just give the deck a sift, cut it, and put both cuts in either slot and let her rip.  A good card shuffler should be standard equipment in anyone’s poker supplies and you’ll be glad to have one.  The downside is that you won’t get to show off your card tricks.
