@albarkhane you have to remember the massive differences between vintage and legacy regarding your magchups, and the power of the cards. I’m not sure any of these cards would be good in vintage lands outside of ancient grudge.
There’s no reason to play something like entomb when we can run vampiric tutor and demonic tutor if we want to.
Cards like nether spirit and smallpox are way too slow in vintage and they cost the deck double black which can be hard to produce. Something like smallpox just makes our deck fall way behind in a blue matchup where our opponent can easily produce a lot more card advantage than we can.
Also remember that graveyard hate is extremely prevalent in vintage. Something like never spirit will just get removed by graveyard hate or gives the opponent extra outs with cage and containment priest, cards that usually don’t affect the deck at all, or very little. It’s also a really bad blocker in vintage. All of our matchups are going really wide (dredge, shops, mentor) or going really large (oath). Presenting one 2/2 every turn won’t be scary at all.
Liliana presents the same issues she’s double black and costs three and there’s no way for the deck to protect her. She’s not good against the decks good matches and she’s too slow to present a really meangingful threat against the bad matches in this deck. Her power level is much less imposing in vintage.
Ravens crime is close to the same vein. It requires a deck that is very heavy on black sources and spends a lot of resources picking off one random card of the opponents choice at a time. This is significantly worse in vintage when spells like recall and time twister are legal because we have to spend a whole turn stripping a card or two and the opponent can get everything back in a flash.
Cards like coffin purge aren’t necessary in a deck that runs 2 bojuka bog and 2-3 crop rotations. It’s a significantly worse option to an effect the deck already has plenty of.
I’ve tested molten vortex and it’s also a really slow option for the deck. It’s slighlty closer to playable but requires a lot more time and more search effects for the deck.
You also have to remember to look at matchups and see where the deck needs help. This deck really struggles against really fast decks like storm and certain builds of mentor. A lot of the cards listed just don’t affect those matchups at all or do too little.
I do think some of these cards could have a home in a vintage turbo depths list. That is also a viable list that I’ve seen work and it has the luxury of being a deck that is heavy in black, can run more tutors, and more hand destruction spells, and can operate on a much different axis. I just don’t see these cards being an option for a lands list in vintage.
