Reddit mentions of Barrier Character Guard Card Sleeves (60 Piece), Matte Clear, 69 x 94mm

Specifically KMC Character Guards. I got mine on Amazon to keep my dumb anime sleeves clean, but they're perfect for any sleeves with artwork, as those suffer wear incredibly quickly.

The Professor also did a review on them, so feel free to observe for yourself.

They do indeed exist. I use the KMC Character Guard Mat and Clears which have a fantastic shuffle feel. The mat texture on the back does make the artwork of your sleeves appear slightly cloudy but it's really not a big deal. I can send you a picture of a side by side comparison if you're interested.

Here's where I got mine: https://smile.amazon.com/gp/product/B00ZBRHRSA/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

I live at both ends of the spectrum.

For the majority of my decks, I'm just not that fussed about it. I use the same plain sleeves for all of the decks (1: so that I can swap cards between them easily, and 2: because I can then buy the sleeves in bulk and save money) and don't care all that much about matching playmats, deck boxes, or anything else. I use the same set of dice, life counters, playmats, and +1/+1-1/-1 counters (from the Commander's Arsenal) for all of them. Tokens that match the decks are nice, though, so I do like to find the appropriate tokens and include them with the decks, though I have also purchased a number of blank, white, plastic playing cards that can be used with dry erase markers so that I can, in essence, have any token I want within seconds.

Having said that, for a handful of my decks I do go a lot further than that, and in one case I'm going all the way. For example, for my [X] deck I'm in the process of trying to acquire four of the Tenth Edition spindown dice (that have the set symbol, an "X", on the "10" side of the spindown), two in Blue and two in Black, so that I can have my life total at the start of the game read "XXXX".

And for my [[Nicol Bolas, the Ravager]] deck, which is going to be the first deck that I ever try to fully foil out, I'm going the whole hog:

• A matching playmat of the Invocation [[Omniscience|MPS]] from the artist's website, signed by the artist (Josh Hass),
  
  
• 5 copies of the Nicol Bolas, God-Pharoah Relic token to use to track Loyalty on all five of the Bolas Planeswakers in the deck. I'm still debating getting a foil version to use for my life total, or whether to go for War of the Spark (Blue and Black) and Hour of Devastation (Red) spindowns (so the symbols match and the colours of the spindowns match his Grixis colour identity),
  
  
• The deck itself is sleeved in the [[Nicol Bolas, the Arisen]] sleeves from M19, which themselves are sleeved in KMC Character Guard Sleeves to protect the artwork on the sleeves. Likewise, tokens for the deck are sleeved in War of the Spark's [[Nicol Bolas, Dragon-God]] sleeves which are also protected by Character Guards,
  
  
• All of the cards, tokens, and Relic Tokens are stored in two deck boxes: the matching Nicol Bolas, the Arisen and Nicol Bolas, Dragon-God Pro-100+ deck boxes, with some room to breathe so that the cards and tokens don't get damaged, and,
  
  
• I'm trying to work out a way to easily transport the deck boxes, the dice, the playmat, as well as the Nicol Bolas Funko Pop figure that I own (to use as a mascot when I play the deck), all in a convenient box or case. At this point I'm thinking that I'll likely need something with custom foam (maybe something as simple as a pluck-foam case such as from KR Multicase) just so that I can fit the Funko Pop figure in (as otherwise an Ultimate Guard SuperHive 550+ would likely work for the playmat and deck boxes).
