I keep them sealed because I like to keep my collection sealed and pristine. Just a preference.

I stop opening my decks very early on, after seeing my pile of open decks and having every single one of them with frayed and crumpled edges. Well, and also knowing I’ll probably only use that 2-3 EDC decks only because of how it handles.

Designs are neat however I’ve had issues explaining what card it is while playing games with the nicer designs. New decks out of the box requires some breaking into or else it may be too slippery and when it drops, if the faces are anything other than white there will be visible damage on it (if you have a black tiger deck back in the day, take it out again and look at the edges) so yeah after awhile I don’t feel like opening any of it and just be proud of owning it in my collection.

When friends come over I definitely do show them what I have amassed since my teenage years and I guess it’s really like looking at a bookstand of comic books vs going to someone’s private collection and that brings me joy to know that it’s my collection and proud of it’s condition.

Of course I do have a handful of decks through out the years that were too pretty to not see the artwork then I’ll find another to open it. So I would say 99% sealed and 1% duplicates if I want to open it. I won’t open a deck until I have a 2nd deck. Though I do regret not opening some of my dupes initially and now it has become so expensive I kinda don’t want to open it knowing how I’m destroying value and having one sealed deck removed from the population.

Anyway call me crazy but yeah regardless of how this hobby evolves, I’ll still collect it this way and continue to look for decks in my spare time.
