Is a mono-black suicide money ball control deck viable in Premodern?

4 Dark Ritual

4 Phyrexian Arena

4 Hypnotic Specter

4 Nantuko Shade

4 Bone Shredder

4 Royal Assassin

4 Icy Manipulator

4 Powder Keg

4 Hymn to Tourach

4 Gerrard's Verdict

8 Plains

16 Swamps

Sideboard:

4 Engineered Plague

4 Ring of Gix

3 Tormod's Crypt

4 Ravenous Rats

==

Bone Shredder comes out against Dreadnought and Ravenous Rats go in.

Engineered Plague goes in vs Goblins or Elves.

Ring of Gix can go in vs Dreadnought or Rock to make sure the fatty never gets to attack.

Okay, so I splashed white for Gerrard's Verdict due to 2 for 1 Card Advantage. There are other ways to build an Arena deck. See below.
