NewDeck B/G Lock (need advise to make it more efficient)

[False Prophet]

Hi, all . This is my first posting.  Looking through the vintage metagame i'm just beginning to think of building a deck that can locked others vintage deck.

Here is my decklist,

Mana Source
1 Black Lotus
1 Mox Jet
1 Mox Emerald
4 Dark Ritual
1 Sol Ring
4 Bayou
6 Swamp
3 Polluted Delta
Total : 21

Artifact
3 Crucible of World
3 Null Rod
3 Chalice of Void
1 Trinisphere
1 Powder Keg
Total :10

Enchantment
3 Exploration
1 Nether Void
Total :3

Spells:
4 Duress
4 Hymn to Tourach
4 Sinkhole
1 Crop Rotation
1 Demonic Tutor
2 Diabolic Edict

Utilities
1 Strip Mine
4 Wasteland

Finisher
1 Helldozer
2 Nantuko Shade

I'm just not sure whether this deck will work or not i need all advise.

In my metagame environment mostly my biggest threat came from

1. Stax
2. Grim Long
3. Workshop Slaver
4. Workshop Aggro
5. Meandeck Oath ( this is 90% i cannot handle)

I intend to build a deck that can locked all those threat.

To lock the mana source i use the Land Destruct recurring with Crucible, and also the null rod (it worked best) but this deck seems it lack in the creature removal. and potent finisher.

As far as i knew i still do not know the alternative, i intend to make it mono black ( a variant of the extended mono black control) but i'm affraid i cannot survive the heavy artifact environment.

The most probable finisher i saw was :
- Phyrexian Negator
- MaskNought (combine the engine between combo and prison)

While the most effective to stop the Tendril based deck i just come in my mind Sphere of Resistance.

But there is only little room in deck, so i cannot make up my mind, the combination of the card that provide the most stable lock.

Hello and welcome to TMD.

Please tell us more about your deck.
What do you want it to do?
Why have you chosen the cards that you have, rather than the alternatives?
In which metagame do you play?
How have your matchups gone thusfar?

Providing this information will better enable all of us to provide better and more helpful feedback.

Why are you running Exploration but no Fastbond?

Also, Exploration is dead later in the game if you have no draw engine or a Crucible lock, so maybe including cards like Necropotence, Yawgmoth's Bargain, Dark Confidant and Night's Whisper would help.

It seems like this deck would take a really, really long time to kill someone.

The problem people tend to run into with this sort of strategy is that you have lots of early game disruption, i. e. Duress, Hymn, and Sinkhole, but your opponent will most likely be able to recover before you can find one of your three finishers.

Shade will only be really effective as a kill later in the game because a lot of your land drops (in this case, permanent mana sources) seem like they'll be devoted to strip-effects, and unless you've established the mana to set up a "hard" lock (with Crucibles / Strips / Null Rod et cetera), it seems likely that they'll be able to recover and take the upper hand.

I recommend finding room for Vampiric Tutor, cutting a Crucible for Imperial Seal (not sure how you feel about proxies, but if you can get one, great), and speeding up the rate at which the deck really wins. As much as I like Confidant, he seems like he'd deal you far too much damage in the long-run because of the sorta' slow kill rate overall, but I do endorse Night's Whisper.

Negator is good.

Best of luck.

Just a thought, but Vinelasher Kudzu could be great in here.
