I think the thing being referred to here is "artificial rarity". All these Vault cards are marked 1/1, though they can be as much as /9 or /10 depending on the colour of stamp, IIRC. Not to throw shade at another company here, but it's one of the reasons I don't have much interest in certain Leaf products. Why have parallels of a card numbered /9, /7, /5, /3, /2, /1?
There are cards that are technically not rare when defined by print run, but still super desirable, such as the Pro Set Holograms, or Starquest Golds. I'd much rather have those cards than a stamped 1/1 of a previously released Bill Guerin card, that's for sure.
And my main point is still, let's say you had a sweet Connor McDavid auto rookie, limited to xx. 10 years later, the company releases completely identical cards, doubling their production while likely halving their value. Let's say you had put together the whole set, and it was a remarkable accomplishment given that the cards were so limited. And all of a sudden the availability doubles. Everyone can pretend finances aren't involved in cards, but everyone knows that's just not true.
