Yes but if Midas gave zero attack speed Slark would not buy it . It is worth mentioning . <| sep |> Close fitting boxers can be just as bad . <| sep |> A Crypt of Agadeem might fit well alongside the list of black creatures . Phyrexian Tower is another great land to run in this list . Gives you a High Market that acts like an Ashnod ' s Altar . Thought Vessel is a good card but generally I ' d much rather prefer running that sort of an effect on a land Reliquary Tower . Much harder to be removed , but it depends on your meta . A Fleshbag Marauder would also compliment the Executioner quite well and you should continue considering it . Quickly glancing over your list , you have alot of targeted removal . I think you should remove some of these spells and swap them out for more board wipes such as Decree of Pain and Toxic Deluge . I myself run a Meren deck which ofcourse has a focus on recursion and attrition , you might be able to grasp some black card inspiration from my decklist decks 061016 merenofclanneltoth , such as which is an amazing card in any deck running black . Goodluck !
