I initially put it on 9 because neither do I think the card nor the deck deserves to be that high on the list in comparison to overall more impactful cards the format offers right now
The issue is even mono-black likely wants to run some colorless lands and Archenemys it is not so good that it is on its own worth building around
Still not as bad as Koma, though
If I am selling a PSA graded card, it is to take all self opinion out of my hands, to let someone else with a standard decide what condition its in
Lands, rituals, tutors, draw spells all live again, then get exiled
Even better, they (and you!) can collect all of the rarest and most expensive cards to appreciate and enjoy without worrying about scalpers or economic inflation
