Definitely still in the works, this deck seeks to combine the power of vengevine with traditional dredge strategies. The idea is to get as many creatures in your graveyard as fast as possible so that you can pull them back out with their own effect. A large portion of the creatures in the deck can be recurred at little to no cost, while the rest make sure all the right things end up in your graveyard.
Crash course in playing the deck: Gravecrawler is a powerful turn one play that seems to never go away. Prized Amalgam, Lotleth Troll, and Skaab Ruinator all allow Gravecrawler to be cast from graveyard. Skaab Ruinator can cast itself which brings back every amalgam, and if you an sneak in a Thought Scour then Vengevine (usually) comes back too. Bloodghast also brings back Amalgam, so try and avoid delving these guys away.
General Tips: If you are hurting for a creature to finish in the late game, always dredge/ self mill BEFORE you play your land for turn. This increases the likelihood you can grab Bloodghast. If you are going to fetch make sure you do it before you dredge/ self mill because you could throw out the land that you want to grab.
Hit it and quit it: if Jace, Magus, Crab, or Troll are in your graveyard, delve these guys first. They can't be brought back once their gone and have probably already served their purpose
Finishers: I feel as though Skaab Ruinator is a massively underrated card in dredge strategies. In longer games where you can grind out your opponent's removal, Ruinator is a massive threat that is difficult to answer. Bonus points if casting Skaab brings back all of your Amalgams. Tasigur, the Golden Fang is a card I'm a little skeptical of but I think that it could be a good fit, definitely needs more testing.
