Greatest accessory I didn’t know I needed?

Mat - got one I love.

Deck boxes - got 3 of the old school mana symbol ones and a bunch of the squire xl (love these)

Katana sleeves, never going back.

DND dice set, d6s, +1/+1 and -1/-1 (these suck. Gold on white? Why? Never need them so it’s okay). Tiny miniature dice.

Counters for keywords, done.

Infinitokens, done.

White boxes for bulk and binder for rares and Stanley for decks I’m not currently going to use. Yup.

What functional (not stylistic) accessory do I need that I didn’t know I needed? At one point I was using dice for life, and number of tokens , and number of counters, etc… I was making tokens with post it’s. I never knew a Stanley was perfect for what it does. Please don’t assume I knew it existed. I’m looking for that new thing that makes things easier in and out of the game!

Edit: The One Ring for my ring bearer, have it too
