Dredgevine M11

i cant see the benefit of flooding this deck with bloodghast. while he fits the theme, it doesnt fit my plays. since the crab is so indiscriminate with what goes into the graveyard, grim discovery is a pseudo-tutor in addition to its other natural advantages. maelstrom pulse gives me the flexibility in destruction this deck needs. master of the wild hunt has given me surprise outs against hard to deal with creatures, including an opponent set up with 2 bsa and a gideon out. i have been considering mnemonic wall as a 1 to 2 of. i also include enough green to hard cast vengevine.
