Do you double sleeve your decks? Why / why not?
I don’t have that much first hand experience but here’s a quick literary review of random internet posts:
Pros
- Cards are protected from liquids
- Keeps foils planar
- Top part of the card is protected from dirt
- Is this really such a problem?
- Some people like the shuffle feel
- Cards remain single sleeved when you remove the outer sleeves and put them into a binder
Cons
- More costly
- Thicker decks, especially in 100 card formats
- Deck boxes become tight, trouble fitting tokens etc.
- Shuffling may become more cumbersome


I double sleeved when I began playing because I thought that’s just what people did.
But at this point, if my cards aren’t double sleeved they feel weird in my hand.
So I double sleeve, but mostly out of imagined peer pressure and habit.
