7th ed. Skullcap/Bridge Discard deck

[Lotus Mox]

Here's the decklist i cooked up: (May T2)

Discard:
4 Duress
4 Ravenous Rats
4 Persecute(this can be so good it's unreal)

The Lock + Card Drawing:
4 Ensaring Bridge
4 Grafted Skullcap

The Kill:
4 Crypt Rats(doubles as Board control)
4 Soul Feast
4 Corrupt

Things to power this nonsense:
4 Blood Pet
4 Dark Ritual
20 Swamp

S/B:
so far I have
4 Unmask
4 Chilling Apparition
What can I add?

I have played only some test matches (vs. random apprentice decks), so far I have won all of them.
The card advantage which Bridge+Skullcap(s) nets you vs. creature decks is beyond belief, nullifying the kill cards of your opponent all the while drawing additional cards during your turn is amazing for just 2 cards which don't completely depend on each other.
This deck isn't even that weak vs. most artifact removal, as it is usually discarded at the time I play Cap/Bridge.
Not to mention that a 2nd or 3rd turn Persecute is quite common and means usually game

What do you think of this deck?
Can it be improved somehow?
I also want to build a red Cap/Bridge burn deck, any ideas for this one?

I was thinking of a similar idea (why is that 7th's best Black cards are all Artifacts? ) Mine was looking something like this:

Discard:
4 Duress
4 Megrim
3 Persecute
4 Bog Down

Artifacts:
4 Ensnaring Bridge
4 Grafted Skullcap
4 Howling Mine

Misc. Spells:
4 Dark Ritual
4 Blood Pet
1 Yawgmoth's Agenda

Lands:
4 Peat Bog
1 Rath's Edge
19 Swamp

The major problem so far is decking myself, which happens occasionally (about 1 of every 7 games) Man, I wish Mindwarper were still in the environment, I miss that funky guy. More to come after I tune this a bit more.

My version goes like this:
2 Blinding Angel
4 Duress
2 Marble Diamond
2 Charcoal Diamond
3 Fountain Watch
1 Dust Bowl
1 Rath's Edge
10 Plains
10 Swamp
2 Vendetta
2 Snuff Out
2 Rout
3 Wrath of God
4 Dark Ritual
4 Dark Suspicions
4 Grafted Skullcap
4 Ensnaring Bridge

Y'know, I'd think that with the creature-heavy environment, Ostracize would go over well.

 

[Cateran Emperor]

yeah, I'm sideboarding 4 Ostracizes as they're one of black's best ways to keep untargetables in check.
