This is a budget dredge deck I am working on. It has been very effective. so far.
Disruption
Inquisition of Kozilek - This card is great, discard a combo piece, a troublesome creature, a annoying removal, or counter spell.
Abrupt Decay - Play carefully, but this card will remove a lot of threats such as Goyf, Delver of Secrets, and other troublesome creatures in the format. Overall very effective card.
Doom Blade - One of the most effective removal card. Sure it can't kill Siege Rhino or Tasiguir. But it does kill annoying creatures. This is sided out a lot more than I'd like, might switch to Go for the Throat.
Creatures
4x Gravecrawler - Put him in the graveyard and just abuse his ability so much. Pivotal creature in the early game and can help late game as damage adds up and they have to block a larger creature.
4x Lotleth Troll - Best creature in the deck, dump all your creatures into the grave with his discard ability, so you can effectively make him huge and abuse cards like Golgari Grave-Troll and Vengevine. He also regenerates for real cheap, keeping him around.
4x Vengevine - a 4/3 with haste that can come down before turn 4, and can put an incredible amount of pressure on the opponent when 3 come down at the same time.
4x Death's Shadow - He can come down later as a beater, or he can be used as fodder for Varolz and give a Troll the biggest boost imaginable.
1x Golgari Grave-Troll - Perfect late game. Dump everything into the graveyard. Perfect cards late game to dump in graveyard are Vengevine, Haakon, Stormglad Scourge, and Chameleon Colossus. Haakon will let you play the Colossus and then put a few counters on Colossus with Varolz, and use its ability. Some times I'll hard cast it and have a huge monster that can regenerate.
1x Bloodghast Only one for budget reasons, might go up eventually, but right now he is staying at one. Super effective and aggressive. All around great card.
1x Chameleon Colossus This card is great. he is unusual, but as a one of he is incredibly strong. He works with Haakon and protection from black is handy when facing Grixis delver, Other dredge decks, Siege Rhino, Dismember, and other crucial cards.
2x Haakon, Stormglad Scourge - Cast from the graveyard late game for a solid beater, and fodder for a Troll.
1x Jarad, Golgari Lich Lord A strong beater late game, and can come back from the grave to beat the opponent some more.
2x Satyr Wayfinder - Dig for lands, and dump creatures into the grave, only a two of because it is incredibly clunky if run at more. I found that out the hard way.
3x Varolz, the Scar-Stripped - Make things huge late game, can regenerate, and make use of all the creatures that can't come back fro the grave.
Other
Grisly Salvage - Go through the deck and grab exactly what you need, or dump exactly what you need.
