I put each card face up to face down alternating them. When this is done. I put them back in the box and then I put them in a clip, I use the metallic ones from ellusionist. I set them in between 2 books and put 2 10 pound free weights on the books. The disk shaped free weights to be exact. I leave them like this for about 3 hours then take them back out and put them all face down and back in the box and back in the clip again. Then I put them back in between the books and put the weights back on them. I will leave them for 12-24 hours. I have fixed every deck I own like this (around 50) at one time or another. Try it out.
