Is this deck mediocre? (Skullbriar)

{"ops":[{"insert":"I've been working on this Skullbriar deck for a while and it's definitely my favorite deck that I've made so far. I want to buy it, but I'd really like some feedback first. To be honest I don't have any specific concerns, but I really want the deck to be better than mediocre. \nAny advice or feedback would be super appreciated\nhttps://www.archidekt.com/decks/3599724#Death_Unbound\n"}]}
