To Pox or not to Pox?

[frontier]

Many years ago, this card was played all over the world. Succesfully, of course. I tried to play it last year in an unpowered metagame and though I wasn`t very satisfied by results (3 wins, 2 loss, 1 draw), but deck showed that ir can compete. Now I`m trying to find an optimal build and to see if it is viable in almost powerless metagame.

Here`s a list (in progress)
Creatures:
2 Nether Spirit

Discard stuff:
4 Duress
4 Hymn to Tourach
1 Mind Twist
4 Pox (it does more, of course)

Artifacts:
3 Chimeric Idol
3 Cursed Scroll
4 The Rack

Removal:
1 Balance
2 Swords to Plowshares
2 Vindicate

Tutoring:
1 Demonic Tutor
1 Enlightmened Tutor
1 Vampiric Tutor

Enchantments:
2 Chain of Mephistopheles

Mana source:
4 Dark Ritual

Lands:
4 Bayou
3 Blodstained Mire
1 Strip Mine
9 Swamp
4 Wasteland

Problems:
a) this deck gains card advantage by supplying card disadvantage to opponent in form of discard.
b) it kills slowly
c) it has problems with fast aggro decks (Suicide Black, Sligh, Stompy - as I mentioned above, my metagame is almost powerless)
d) I have not tested yet it against quick combos decks

Any ideas or thoughts on this deck?

if aggro is a real problem, maybe night of soul's betrayal or mutilates would work well for you, it's just getting to the 4 mana before they kill you that could be a problem

One balance usually solves this problem, but I need something in a SB

-3 Cursed Scrolls. 

I just don't think this is good enough in Vintage.  Especially since Null Rod is such a powerful tool against well, everything.

Mind twist seems really bad, you got almost no acceleration, so it will most likely just be a bad hymn...i'm also not really sure which decks this can beat? Seems really slow and clunky to me.
