Lurker 2-Son of Night

 But we're just gonna shorten this to Lurker 2. 

4 Jet Medallion

1 Nightmare
1 Myojin of Night's Reach
1 Bringer of the Black Dawn
2 Korlash, Heir to Blackblade
1 Ob Nixilis, the Fallen
1 Ihsan's Shade
1 Reiver Demon
1 Visara the Dreadful
2 Magus of the Coffers
1 Maga, Traitor to Mortals
3 Twisted Abomination
1 Stronghold Overseer
4 Scion of Darkness
1 Phyrexian Obliterator

4 Dark Ritual

21 Swamp
2 Cabal Coffers

3 Forced March
3 Drain Life
2 Corrupt

The premise behind this one was to make a big mana/Black legends deck. Obviously, there's a whole lot that can be updated from here, but I'd like to try and keep the premise going-including keeping the Jet Medallions if I can. 

My first thought: cut Stronghold Overseer (shadow OR flying, I do not need both), Bring of the Black Dawn, Myojin of Night's Reach (I can do better for 8 mana now), Ob Nixilis (there really isn't enough land to make this worth my time), Corrupt (same problem), and Scion of Darkness.

That's ten cards that I can replace to make a better deck. Let's go.
