Been away from magic for a while. Just recently sparked my enthusiasm again, so got a couple of new decks of cards. The problem I'm having is, I'm finding them slipping and sliding all over the place. Is this just me because I've not played around with any for a while? Or do others experience issues with a brand new deck and it's just a case of getting them working?

Sure, new decks are a little stiff, but I often break out a new deck in my restaurant work. I haven't had any problems shuffling or executing the necessary sleights. You just need to get a deck to reside in your hands on a more consistent basis.
My opinion of course.

Newsround -- This is exactly the kind of question that will make you appreciate the Magic Café's "advanced search" function. Just click the word "advanced" to the right of the search box at the top of each page. Then, type in a phrase like "breaking in a new deck" or "breaking in a fresh deck" and select the "exact phrase" option. Presto and abracadabra, you'll find lots of answers to your question!

Thanks for the replies. I had tried a search, to no avail. I didn't think of using the advanced search. Just done that now, thanks for the advice

I agree about just handling cards more. I am not there yet, but David Williamson seems to open a new pack multiple times a show and he is flawless with those cards.

I prefer the cards brand new with very little break in. I tear off the side tabs on the box, trash the advertisement cards, put a VERY slight bend lengthwise so I can do a thumb count getready easier for a DT, and that's about it. I like the way new cards fan, spread, and faro better than 'worked in' cards.
