How Dex Fair is built — Naganadel & Guzzlord GX
Dex Fair is what this card actually sells for. It is more than a sales average: it weighs real completed sales of Naganadel & Guzzlord GX and its closest comparables, throws out sales that don't belong — graded slabs, one-off outliers — adjusts everything to Near Mint, and cross-checks the result against the wider market.
That is a different question from the one a price guide answers. A guide reports what copies are listed at; Dex Fair reports what buyers actually paid. On SM — Cosmic Eclipse cards the two routinely disagree, and the gap is where a good buy hides.
Every Dex Fair number carries a confidence level and the count of sales behind it, so you can see how much evidence it rests on rather than taking one number on faith. This one rests on 63 completed sales.
