The idea of this deck is the same to any of the modern/legacy dredge deck. Make your graveyard your hand and combo off from there.
As in most dredges the "key components" to get the dredge going is Stinkweed Imp /
Golgari Thug
/ Life from the Loam + Faithless Looting and/or
Ideas Unbound
to either dredge from the card draw abilities or just discard them from your opening hand. Discarding these cards can also be done with Oona's Prowler who also can work the beatdown and force discards(Though only when it suits the opponent).
Once the graveyard is stacked with the help of the o so good dredge mechanic this deck has 2 ways to combo of. The peices that are important to have in the graveyard is Bridge from Below or/and Vengevine and a "supporting" Gravecrawler.
In the case that you wan't to combo off bridge from below you do this by sacrificing any creature to a Viscera Seer creating up to 4 zombie tokens. With these tokens on the battlefield you can then cast Gravecrawler from your graveyard and reapeat the process X times where X is the amount of black mana you have access to. This combo also makes your Vengevine's return to the battlefield who in their turn can be sacrificed or engage the enemy.
The combo with Vengevine requires atleast 1 zombie on the battlefield and 2 Gravecrawlers in the graveyard + 2 black mana, or Viscera Seer and 1 zombie and 1 Gravecrawler in graveyard + 2 black mana or sufficient cheap creature spells in your hand to cast atleast 2. If lucky you can get this combo off on about turn 3-4 with a couple of Vengevine's in the graveyard and get a strong early board position.
These are the main ideas of the deck but if you fail to combo off you can in desperate moments go for a regular beatdown with Gravecrawler, Vengevine and Oona's Prowler.
I've been thinking of also putting in an Unburial Rites +
Griselbrand
/Iona, Shield of Emeria for a strong power creature turn 4 or Unburial Rites +
Borborygmos Enraged
turn 4 which combos with Life from the Loam with can lead to 9 burn a turn(or more) with a graveyard stacked with lands.
The mana-base is very "self hurting" which can lead to bad situations in slow games. To help with this i've stuffed in 1
Gnaw to the Bone
which can give enormous life boosts that sometimes lead to a victory.
Any suggestions/feedback for this deck would be greatly appreciated since i'm not especially experienced with dredge. Especially suggestions for sideboard cards would be great!
