Same lands as the vengevine list due to most of the cards in both decks being the same. Also I will not be creating sideboards yet for these decks yet. I'll start with a vengevine list then a bridge from below and finally a craterhoof list. I will however post my own budget deck tech tomorrow with suggestions on how to make dredge for around 20-50 dollars instead of 500 which personally is way to much for a deck I mean i understand why decks like dredge need gpod mana fixing and such but still 500 dollars is a lot but as I said it's just my opinion.

So now i will show 3 different deck techs, however I will mention these are my own designs they are based off of the decks that have done well on a competitive level. The reasoning behind each is the same, they all replace themselves with card draw and get cards in your graveyard. Also almost every dredge deck will run insolent neonate, faithless looting, and thoughtscour.

Most decks do have the narcomoeba and bloodghasts, along with the most common dredge cards such as golgari grave troll and golgari thug. Now the main difference between dredge decks are the win conditions, most decks wont play bridge from below and vengevine, or prized amalgam along with craterhoof behemoth, the main reason behind this is resource management.
