It’s called Black Lotus, I think. Not totally sure since I have never been interested in mtg as anything but something to have fun playing at a medium-high level, but I’ve heard copies of their original release go for many thousands of currency notes. Much to expensive for my means, but that’s okay.

I’ve been having a great time with my Vivi/Dragon Typhoon combo lately. Most everyone thinks I’m playing a burn deck until they’re up against 10+ dragos out of nowhere and it has yet to stop making me giddy when that moment comes.

Any serious guitarists will let you know their holy grail.

It’s not any guitar; it’s another guitar.

Super subjective, but for my handtool woodworking, my grail is a pistol grip Stanley 610 drill. Do t know why, but ever since I saw one, I’ve wanted it!

For me with gaming (both playing and dev), a Steam Deck. Never wanted anything more in my life, seeing people have them and barely use them hurts. But I’m on long-term sick leave and live paycheck to paycheck, not able to save anything and it doesn’t look like that’ll change anytime soon. And it’s more than just wanting a cool thing, all I have is a shitty laptop from 2010 that barely plays 1080p video, and a TV I found outside that gets so warm that it’s hard to sit in front of for longer than two hours at a time. The laptop has no battery so it has to be used with the charger connected all the time and it’s too heavy to comfortably use anywhere but at a desk. I also have back and knee problems and having something like a Steam Deck would allow me to play and develop in bed or on my sofa and save me some pain.

The Klon Centaur is a highly praised guitar pedal that, since it had a limited production, has an unsustainable price for most of the players (some people paid up to 20.000$ for one).
Luckily the circuit is easy to copy and over the years many clones from other brands came out. But still, the original one holds a special charm and has become a higly collectible trinket.

I’ll try to keep these both short.

Magic the Gathering - the “Power Nine”

There’s 9 cards from the first few printings that were simply deemed too powerful. Once they were out in the real world, the folks in charge realized they weren’t fun to play against, and resulted in wildly uneven games. In extreme cases, the opponent could lose without even getting a single turn. They’ve been banned from every format*, and have never been reprinted*. *Except of course when they are. https://mtg.fandom.com/wiki/Power_Nine

Model railroading (O-gauge). Lionel 770e Hudson

For O gauge size, the train everyone wishes they had in their collection is the 1937-1941 Lionel 770E. This was a super-unusual toy for its day, pretty much everything else had been aimed at younger children and a lower price point. Lionel decided to take a gamble and build a hyper realistic scale model that was aimed at young adults. It was honestly not a great seller in its day due to the high price point and the looming threat of WW2. But it was, and still is, considered one of the highpoints of the industry. You could argue that the current Lionel company is founded on this concept, as their VisionLine products are focused on ultra-realistic toys for grown ups (which will always be funny, as yes, our track has 3 rails). https://www.youtube.com/watch?v=FOdDw0-Tflg

Electronics / hardware hacking and development. I have a Saleae Logic Pro 8 which is probably the most expensive thing I’ve ever bought in a weight to cost ratio at £933 for 60g.

Works fantastically, though, and the analog function and high sample rate is what truly sets it apart from other analysers.

I don’t have a personal need for a 16 channel analyser currently, so couldn’t bring myself to cough up the extra £500 for that model.

I’m a book collector, sadly most of the books in my preferred address are, and forever, will be out of my reach. My holy grail is The Magus by Francis Barrett (1801), it’s basically a guidebook to the occult. I’ve got a facsimile edition published in 1970 but I’ve never seen or heard of a original copy for sale - not that I’ve searched, I don’t wish to see an old man cry.

I’m into fly fishing and the holy grail for many anglers is catching native brook trout. Most trout are stocked or introduced with wild reproduction. Brookies were plentiful at one time before the loss of habitat. There are those that crawl on their hands an knees through brush to catch a 6" fish out of a stream you can jump over

Depends on the hobby, but this list is for me, idk if there is a consensus
