(Far as I can tell, that may have been Mark Poole, who started numbering some early proofs but found the practice onerous and abandoned doing so for a number of years.) Numbering highlighted the true limited edition status of these cards, and most artists have followed suit
Cryptic Caves
It is nice that it triggers when you counter something cheap, as countering something that costs less than three feels particularly bad with this kind of card, so at least you get a consolation prize This sort of bounce effect is usually solid card not usually amazing because it is card disadvantage, but in a lot of decks the tempo is big and when you can use it to trade 1-for-1 and get tempo it feels pretty absurd
Not immensely popular, but clearly good enough to garner some attention (if you read any of Rally the Ancestors , you'll know I like my commanders a little niche)

Luckily, Wilds of Eldraine boosters will sell for something much closer to normal prices
