Orzhov Extort Rush Deck

[EM34]

I'd appreciate any thoughts on this build. The idea is simple enough: summon numerous extorters, profit from cheap casts to extort consistently, and finish anything remaining with Immortal Servitude and/or Sublime Archangel.

2x {Thrull Parasite}
4x {Basilica Screecher}
4x {Syndic of Tithes}
4x {Tithe Drinker}
4x {Blood Artist}
2x {Vizkopa Guildmage}
2x {Cartel Aristocrat}
1x {Thalia, Guardian of Thraben}
2x {Sublime Archangel}

4x {Sign in Blood}
3x {Blind Obedience}
2x {Orzhov Charm}
3x {Immortal Servitude}

4x {Godless Shrine}
4x {Isolated Chapel}
1x {Vault of the Archangel}
7x {Plains}
7x {Swamp}

Maybe  {Crypt Ghast} to get two extorts per swamp

This ^^^^^

Possibly  {Liliana of the Dark Realms}

I both like and dislike {Thalia, Guardian of Thraben} here I like Thalia cos lests face it she is a boss but with all the spells you are wanting to cast even the one of her could stuff you up

Thalia's in here largely to be brought out with Immortal Servitude. She makes it more costly to deal with the swarm. Fair point, though.
