So I'm working on a Standard vampire deck and I'm wondering what should be cut, what I should be looking for (besides 3 more copies of Stromkirk Noble) and what sort of land ratio to go with:

1 Stromkirk Noble
4 Bloodcrazed Vampire
4 Rakish Heir
3 Falkenwrath Marauders
1 Olivia Voldaren
4 Child of Night
1 Sengir Vampire

3 Assault Strobe
4 Nightbird's Clutches
2 Curse of Stalked Prey
4 Volt Charge
4 Grim Affliction
1 Tezzeret's Gambit
1 Fireball

Nonbasics:
1 Stensia Bloodhall

The proliferate is cute, but largely inefficient. You should definitely be running Brimstone Volley over Volt Charge, and probably lower your mana curve in general. And why 1x Fireball?

Most of this is stuff I actually have (gutted away my collection a while ago). Other than the Volt Charges and the costly Bloodhall I don't really have any direct damage. Any other cuts I should make? Any proliferate that actually makes sense (besides the Gambit)? I think having 3 Falkenwraths is a bit much because I've generally won with him, so I could see dropping him and maybe the Sengir.

Also, I forgot to add I have 3 Assault Strobes in the deck.

I haven't picked one up yet, that's all.
