New deck idea.

Alright, I have most of these cards, and am thinking about spending the $ to finish it. Tell me what ya think :P

Creatures:
2 Inkfathom Infiltrator
4 Hypnotic Specter
2 Ghastlord of Fugue

Enchantments:
3 Helm of the Ghastlord

Land :
10 Island
10 Swamp
4 Underground River

Planeswalkers:
1 Liliana Vess

Spells:
4 Boomerang
4 Cancel
4 Cryptic Command
4 Terror
2 Mind Rot
3 Ponder
3 Tyrannize

I have no sideboard atm, as I'm unsure what would really screw this deck over.
