I am trying to build a Dark Depths deck with a control role. I previously tried an aggro type of deck with 4 Vampire Hexmage and 4 Phyrexian Dreadnought, but it was really unstable. It could go really well, or die to your own deck!

What I am trying to build now is some kind of control with a fast finisher.

I would like to discuss if this deck has any chance in the meta.

The list:

4 Vampire Hexmage
4 Tarmogoyf

4 Force of Will
3 Daze
3 Spell Pierce
4 Counterbalance

4 Brainstorm
2 Ponder
3 Sensei's Divining Top

3 Pernicious Deed
3 Smother
1 Ghastly Demise
1 Maelstorm Pulse

4 Underground Sea
2 Bayou
1 Tropical Island
3 Dark Depths
6 Fetches
1 Urborg
2 Wasteland
2 Basic Lands

I will add some comments on my choices:

4 Tarmogoyf and 4 Hexmage: Both needed. One for the combo, the other is just nuts! One problem of the deck is that it has just 8 creatures for now. How can we solve it? (2 Vendillion Cliques would be great in here)
I tried Dark Confidant and I know he is a power house, but I wouldn't run him with all the aggro decks around (minor problem) and I didn't know what to cut for him.

4 Force of Will, 3 Daze, 3 Spell Pierce, 4 Counterbalance: I love this combination of counterspells. It's very effective.

4 Brainstorm, 2 Ponder, 3 Sensei's Divining Top: the cantrips. I added the 2 ponders because this deck wants a lot of manipulation and because I needed 20 blue cards to support Force of Will.

3 Pernicious Deed, 3 Smother, 1 Ghastly Demise, 1 Maelstorm Pulse: first of, the split is made for a better counterbalance curve (currently 21 drops at 0, 13 drops at 1, 18 drops at 2, 4 drops at 3 and 4 drops at 5).
I know many of you will think: what?? Pernicious Deed and Counterbalance together? They are anti-synergistic! And they are, but I think that with all the aggro and low cost permanents running around it's a good choice.
There are 5 single removals in the main and 3 board sweepers, so we should manage to keep aggro down until a CB landsor a 20/20 fattie and then it should be much more easier.

21 Lands: the configuration sucks, I know. Too many non basics, 3 that don't give mana unless Urborg is on the table and 2 that give uncolored mana (wasteland) in a deck that needs UU for CB and BB for Hexmage. This is a problem that we must try and solve.

I wanted to add Crop Rotation to smooth the deck's manabase, but didn't have slots and with all those cantrips I think that the deck is able to find the right land when you need it.
Btw I added 2 Wasteland because of the Depth's weakness to other Wastelands.

Currently there is no sideboard, that is a secondary problem. First we have to optimize the main!
If you have suggestions on some cards you would like to add, or to cut please suggest!
