Since we have your attention on the tread right now I kinda wanted to bring up the issue of card prices. Now I know deckbox has its own way of calculating pricing for cards and I have heard of the issues with TCGplayer in the past and everything. I get it. However the prices here compared to the rest of the collection universe has been exponentially increasing and since all the recent card spikes and such has just exacerbated the issue.
Currently on deckbox my collection is worth $51,000 which is exciting to see, but I also have my collection in the DelverLens app since it allows me to see other price structures and according to the app my collection, with TCG Market pricing, is only worth $40,000. That is over a 20% increase in value here compared to the rest of the world. A 20% difference is extremely hard to justify as some sort of variance between systems. This is a very well known issue and because of this many of us go to TCG player to check prices before making trades here because we just can't rely on the prices. This is just extra overhead which makes using deckbox a little less desirable.
It also does not seem like prices are really updating nearly as much as they should be or not in the best way possible.
I have a Mythic Edition Jace, the Mind Sculptor. You can see in my inventory today that it is $313.37. According to TCGPlayer it is about $180 ($210 mid). According to MTGGoldfish it is about (which uses TCGMid for prices) it has not been over $300 since January 2019. That seems to be about the last time I saw the price of the card change on deckbox was about 2 years ago.
I also get the other side of the coin too. Right now my highest priced card is a foil 7th edition Strands of Night at nearly $600. There is no way in HELL that card is $600. It was steady at about $36 until some smacked-asses decided to up the price of TCG Mid (and probably thus their collection's price) by putting them up for $600. Same thing happened with Magistrate's Veto a few months back when one guy put them up three of them up for between $1500 - $2000 each. I'd love to see my collection jump an extra $1500 over night, but when the card is really worth like $5 ... moral of the story never use TCG Mid for pricing.
I would LOVE someone to want to make a trade for my Strands and give me $600 in value for it, but I would not even feel right accepting it because I know that price is inflated by 1500%. Since I know it is obviously erroneous I then have of go check another website for a price and since I have to compare apples to apples I have to check all their card prices which just takes a lot of time to even out a trade that way. Then their is always the issue of the other party not using that scale for price or seeing a trade that appears uneven because of deckbox pricing and making it seem like I am trying to rip them off in some way. Where as if everything was just more inline with the rest of the world that kinda thing is just eliminated.
I have not made a trade with just deckbox prices in a year and a half maybe? I have had to check other websties for prices because everything is just so off from reality overall. I'd like to get back to the point where I feel I can trust deckbox a little more on pricing again.
I would like to say that if you are willing to follow Scryfall's lead with the etched foiling that maybe you could use Scryfall for pricing. Their prices are not an fluid as TCG obviously, but they seem fairly consistent with actual real prices. And then in that case you could even incorporate the scryfallid into your database and maybe make it available for exporting thus making it even easier for everyone to cross reference between systems since it is such a common identifier these days. Just and idea on that front.
