Some of the old pain lands might be fits for your mana base, and they won't cost you your left testicle. Cards like Sulfurous Springs, Caves of Koilos, and Underground River are good lands you can add without going broke. City of Brass, Reflecting Pool, Undiscovered Paradise, and Gemstone Mine are nice, affordable options for getting whatever color you need.

You should try to upgrade the landbase too. If not Marsh Flats or Godless Shrine, at least Concealed Courtyard or Caves of Koilos or Isolated Chapel?

Hi, i'm not an Expert of Extortion deck, but i can tell you that your mana curve is really high for modern's standard. You need to make it faster or to slow down your opponent. Since you play black and White you have a good number of choices with removal and discard and some good budget options are Duress and Despise depending what you fear more between creatures or other spells (maybe combo pieces). So you would not waste your 1st turn, even more you can damage your opponent game.

Then, talking about your manabase, i agree with your decision of not playing too many tap-land, but i still want to suggest you a pair of bicoloured, budget lands that can work in your deck. The first (and weakest) is Scoured Barrens, which is essentially a Forsaken Sanctuary which also gives you 1 life. The second and stronger one is Caves of Koilos. It costs you 1 life per activation if you want B or W mana, but it doesn'enter tapped and in your deck 1 life should not be a lot. Then again, if you have a higer budget, you can also use Isolated Chapel.

landofMordor: I completely forgot about Secure the Wastes. I like the the flying spirits from Spectral Procession, but I do get more token production potential from the wastes. What about running Secure the Wastes in place of Raise the Alarm? I feel like with this deck I am going to win with the fliers before I win with any soldier tokens. If I play a waste one turn 2 for a chump block oh well, but the chance for 3+ tokens late game could be a game changer. As for Duress, I am definitely going to consider that card for at least my sideboard for now. It may be incorporated in the main deck based on my meta. Thanks for the suggestions!

Hyperalgialysis: I think I may be good on my mana, but I will definitely keep Llanowar Wastes and Caves of Koilos in mind if I find that my mana becomes an issue. The same things goes for Abundant Growth. Hidden Stockpile is an interesting suggestion and something that I will keep in consideration. Hopefully I will be making plenty of tokens to get value out of it, but only time will tell on that. Doomed Traveler could be an option as well if I ever need early chump blockers against a red deck. Thanks for the ideas!

You could try Llanowar Wastes and Caves of Koilos for budget mana fixing. Once you get an urborg in play they will tap for a black mana without damage. Most fetch and shockland plays hit you for 3 and this would give you the fixing for 3 turns and the same damage. The pilgrims are fine, if you go the painland route Abundant Growth is the same cost and self replacing. The other thing I would suggest is Hidden Stockpile. Free tokens is good, and this will give you some value as they get removed. Doomed Traveler is really good too.

Some cards you might want to consider...

Inquisition of Kozilek for card disruption

Shadow of Doubt to stop fetching and combos

Collective Brutality for the utility

Path to Exile white staple card, I'd take out Doom Blade

Batwing Brume is kinda cool

For land I'd do something like this...

1x Caves of Koilos4x Godless Shrine4x Isolated Chapel1x Miren, the Moaning Well5x Plains5x Swamp2x Vault of the Archangel

Hope this helps!

I will give that a try. Appreciate you takin the time to check this out. It's a fun archetype and I'm glad I finally got the cards together. I'll probably toss in a 3rd copy of Caves of Koilos until I get another Godless Shrine.

I'd say Emeria, The Sky Ruin would be helpful, even if you run just two or three. They don't always come online, but they're fantastic when they do. Makes running boardwipes far more comfortable, if you ever wanted to include those.

Spire of Industry, Caves of Koilos & other such painlands could tap for colorless or white, without tying up one of your creatures (a la Holdout Settlement).

Also, possibly of interest: Eerie Interlude
