Toxboy gave a nice overview above. Let me add some.
My older list before thespian stage was more grindy, winning with only
Bloodghast and
Mishra's Factory
http://sales.starcitygames.com//deck...p?DeckID=69791
Crop Rotation was in the sideboard and functioned as creature removal with
Cabal Pit and
The Tabernacle at Pendrell Vale and also worked as graveyard hate with
Bojuka Bog and to fetch
Karakas against reanimator or sneak and show. I love this build and still think it is a better deck than the ones with
Dark Depths but being able to win fast with Marit Lage was a necessary concession to time concerns at tournaments(I started 3-0-3 at a Legacy Open bc of slow Miracles players).
Entomb does a lot of things for us too, it can grab
Life from the Loam,
Bloodghast, a land,
Cabal Therapy, or
Raven's Crime allowing us to start attacking with creatures, attack their hand, or start an engine like
Wasteland-Loam (Even better with Tabernacle).
Toxboy stated how important
The Tabernacle at Pendrell Vale is, I agree but if you don't have access to one just be aware that you need to gear you deck to it, Tabernacle does a lot of work answering multiple threats while keeping our opponent from adding to the board, if you don't have one I'd recommend playing
Pernicious Deed main as it also helps clean up the board and answers almost everything. There are a lot of game when I fall behind but if I find I Deed I am right back in it or now very favored to win. I'd say about half our cards are objectively powerful but all become awesome as part of an engine.
Liliana of the Veil is a powerful magic card as is
Smallpox but when combined with
Bloodghast and
Life from the Loam they are even better. I could list 100 card interactions that make individual cards better than usual in our deck.
There are a lot of cards that fit, I probably have 200 cards in my binder just for my GB Pox.
Good luck with building, we are here to help and learn,
Josh
