Deck Primer / Description

Hello, this is a new GB commander deck I'm working on. For now, I'm trying to make it work with Skullbriar, the Walking Grave championing a +1/+1 counters synergy, teamed-up with the rest of the 99. I'm looking for any suggestions and tips anyone can give me in order to improve it! I've also considered on using Hapatra, Vizier of Poisons or Jarad, Golgari Lich Lord as commanders but I don't know if they would work without changing most of the deck, bearing in mind that I'm on a tight budget atm. The deck is intended for kitchen table MTG and maybe an occasional visit to my LGS, so I wouldn't be looking for US$10+ singles yet, anything below that is very welcome.



I'm not sure about Tragic Slip, I might try Languish, or Retribution of the Ancients. I considered Abrupt Decay, but I'd like to go be able to kill bigger threats (CMC wise, though I have Tragic Slip 'cause I have one in my collection lol).



I'm not sure about the number of lands I'm running. Should I add more? Or if I cut some of the utility lands, which lands should I cut first? And what should be the replacements? I was thinking on adding Twilight Mire and Overgrown Tomb soon.



Thank you very much!
