I am currently working on this list:
Maindeck
//Lands: 20
12 Swamp
4 Wasteland
4 Mishra’s Factory

//Spells: 24
4 Dark Ritual
4 Duress
4 Hymn to Tourach
4 Sinkhole
4 Smallpox
4 Pox

//Artifacts: 15
4 Mox Diamond
4 The Rack
1 Cursed Scroll
2 Phyrexian Totem
3 Crucible of Worlds

//Creatures: 2
1 Nether Spirit
1 Undead Gladiator

Sideboard (quite sure slots)
3 Tormod’s Crypt
3 Pithing Needle
4 Engineered Plague
(completely debatable slots)
2 Zuran Orb
2 Perish
1 Darkblast

I'd like to ask your experience on a few points:
1) are 20 lands enough for 4 Mox Diamond?
2) how many Crucible of Worlds: 3 or 2?
3) how many Phyrexian Totem: 2 or 3?
4) The Rack: hot or not?
5) Cursed Scroll: hot or not?
6) Nether Spirit: 1, 2 or 3?
7) any idea to draw a bit? (I am going to try Undead Gladiator)
