Thoughts on the first look:
Cut
Bloodfell Caves,
Wind-Scarred Crag and
Scoured Barrens. Replace them with
Ash Barrens + 2 Basics.
Fabled Passage might also be an interesting option, but I think it would depend on the price after the reprint is out.
Then, replace
Bojuka Bog with
Soul-Guide Lantern.
Bojuka Bog only taps for B and enters tapped, this makes it a bad land, and a grave hate that only works on sorcery speed is often to slow if you really need it. The Soul Lantern can be used on instant speed, hits all opponents and if you don't need the grave hate, you can still sac it for a card draw. 1 card for 2 colorless isn't something exactly cheap, but its okay.
I understand the idea behind
Falkenrath Noble, but he's to expensive for it's effect and he's no human. In stead you could add
Disenchant,
Tragic Slip or
Crush Contraband for some more spot removal.
Anointed Procession seems nice, but it feels a little out of place budget wise. unless you've already got it, I would suggest investing a little more in better lands in stead for a better overall performance of the deck.
