[Deck] DreadStalker

Interestingly, Jace's Phantasm has a slight fit to this deck.

Jace's Phantasm (U)
1/1 Flying, +4/+4 if opponent has 10 or more cards in Graveyard.

The idea how Jace's Phantasm fits naturally in the deck is its slight synergy with Vision Charm (milling your opponents for 4). In the same light where you can Charmill yourself for 4 to setup for Tombstalker, I'm somewhat convinced that the Phantasm is potentially more effective in the mid-game than Tombstalkers.

Some rough notes (I will need to test at some point)
Tombstalkers usually come down on turn 3 in the deck (you want to keep a mana open against Daze, for Brainstorm or Pierce for protection to maximize the effectiveness of Tombstalkers surviving). So ideally, you are swinging with Tombstalkers on turn 4 with protection.

Jace's Phantasm will ideally come down on turn 4 or 5 depending if you setup with a Vision Charm, so it will be 1-2 turns slower and that's the biggest drawback of running this guy instead of Tombstalkers. However, once you hit the mark of 10 cards, every Jace's Phantasm becomes increasingly mana-efficient than subsequent Tombstalkers. I need to see if shifting the deck towards more early disruption and focusing on kills on turn 6-7 is worthwhile. For most parts, it is not easy to get turn 4-5 kills with this deck since it would mean that you need to bank on Dreadnought/Tombstalker surviving.

Of course, Delver isn't the card that's replaced, but a hypothesized list for Charmnought could follow as:

Lands: 18
4 Wasteland
4 Delta
4 Strand
4 Underground Sea
2 Island

Creatures: 12
4 Delver
4 Dreadnought
4 Jace's Phantasm

Cantrips: 8
4 Brainstorm
4 Ponder

Deck-enablers/disruption: 8
4 Stifle
4 Vision Charm

Permission: 14
4 FoW
3 Pierce
4 Daze
3 Removal

I personally think that you can even go with a monoblue build running Dismembers for removal and adding some Mishra's Factory for some added threat density with this given build. You dodge the BB restriction of Tombstalker's cost, so depending on what you're fighting against, a UR build with Bolts and Forked bolt and REBs in the SB could also be decent.

Just an idea throwing it out.
