MTG players, need help with my deck

[robomummy]

So at my LGS we are having a Magic tournament where each player must build a deck representing one of the ravnica guilds. The deck must only have cards that have something to do with the guild we chose. I have chosen to build an Orhzov deck, comments and criticism welcome. (Note: this is made up of cards I have, i'm not looking to buy a lot of new cards but I can buy some if there are specific cards that will work.)

Creatures:
Kingpin's Pet (x4)
Knight of Obligation (X2)
Syndic of Tithes (x3)
Basilica Guards (x2)
Vizkopa Guildmage (x2)
Thrull Parasite (x2)
High Priest of Penance (x3)
Blood Baron of Vizkopa
Deathpact Angel
Teysa, Envoy of Ghosts
Obzedat Ghost Council
Treasury Thrull (x2)
Alms Beast

Artifacts
Orhzov Keyrune (x2)
Orzhov Cluestone

Enchantments
One Thousand Lashes (x4)

Spells
Dark Ritual
Merciless Eviction
Diabolic Tutor
Murder (x2)

Lands
Orhzov Guildgate (x4)
Swamp (x9)
Plains (x9)

I'm only counting 58 cards there, unless you forgot to add something?

Have you thought about capitalizing on Extort?

[robomummy]

There are 60 cards there, forgot to add 2x basilica screechers.

Also I have 19 extort creatures in the deck.

[Hellbreaker]

19 Extort cards are not enough!

That said, did you consider Tragic Slip or Bonds of Faith? Or I'm guessing neither are Orzov enough?

[robomummy]

tragic slip might work if I can get some, I don't see a lot of use for bonds of faith though as I don't run a lot of humans and the only one who really does is the Boros player.

Also I know 19 extort is not enough extort but Im trying to rework my deck to be less reliant on extort since my opponents know that I like that mechanic and usually find ways to counter it.

[Hellbreaker]

Oh, Bonds of Faith has more uses than just buffing your humans. In fact, that's the least valuable use of it.
You say you wont be seeing a lot of humans apart from the Boros player (and even Boros has goblins). So Bonds of Faith would be very useful for blocking certain cards, say Captain type cards that buff attackers (Boros has those) or blockers. Remember, you can enchant an opponent's cards.

[Craig]

Have you read this -Article- yet? I was reading through it and it appears solid enough.

[doosra]

drop teysa, she is just awful. if you can get Athreos in as he fits the orzhov theme very well and keeps the creatures coming back or draining the opponent

[robomummy]

how is tesya awful? a 4/4 vigilance, protection from creatures that kills any creature that does combat damage to me and gives me a 1/1 spirit? pair it with the 2 Grave betrayals I just put in. With these two cards anything that deals combat damage to me gets killed and comes under my control as well as a flying spirit. I'm not seeing the bad side.

Also quick note, I dropped the two vizkopa guildmages to put in two grave betrayals. Also dropped two basilica screechers for another high priest of penance and a basilica guard.

[Geneva]

Hey, how ya doin'?

I personally prefer the original Teysa better than the new version. Especially with Lingering Souls. Speaking of which, I'd strongly recommend a few Lingering Souls cards. It's incredibly Orzhov flavoured and can be downright overwhelming when played right.

[phayze]

If you can get them, the shock lands are usually better than the guildgates. Godless Shrine is the one youre looking for, and if youre planning to just run extort, it may be your best best.

otherwise, a great cheap buff card would be shadow lance. fits orzhov and has great potential, along with Pillory of the sleepless. Belfry spirit gets you some blockers too.
