Using ultra pro deck protectors in black w/ the rough backs (both new, tighter-fit ones and their older ones) and they both fit just fine. No sticking at all.
But i want to get Dragon Shield sleeves in diff. Colors, as they don't have the annoying hologram that covers up text at times...can someone confirm the fit of those in the spellbooks pls?
also, ive found that it's better for me to 'bottom-load' the cards in the sleeves so that the open edge is on the bottom, which makes it easier to pull them out of the books when playing.
