In general, this project has been conceptualized based on how easy we can "proc" Korvold and how disgusting his trigger is to get, while serving as the absolute entry point into the commander (which does have a very high optimization ceiling should one be so inclined). But if one didn't want to spend thousands like that, the floor of the deck is still quite reasonably high as well. I'm impressed, to be honest. I didn't expect things to turn out this smooth but here we are.
Disclaimer: The bulk of this deck's price point is in the tutours three ABU duals, Sylvan Library, & select P3K cards but if you cut those you could pick the rest up for pennies on the dollar. Then you could even proxy some of the high $ cards since this is an unsanctioned format with nothing on the line, which is a pretty fair line of thought given the role of this list. Aside from that, my only stipulations are that every card should have an English print and be reasonably attainable (which is why I chose to exclude Mana Crypt, it's only English prints are in blackborder; it has an obscure Spanish print that is white border if you want to look for it...it's still $200 though, which I've chosen to pass on. You could easily replace it with Basalt Monolith if you didn't want to track it down, though. Similarly, you could replace Imp. Seal with Cruel Tutour for price reasons). However it's worth noting that without these key outlier cards, you could build this for relatively cheap which makes this an enticing project to try out. You could even get some blackborder perfect fits from SCGames if you wanted to still use your investment without buying new blackborder versions of the expensive cards themselves.
