Yo, have you considered Cynical Loner for this deck? She seems like a decent Station enabler & is basically an Entomb on a stick. I could understand avoiding something like this to avoid repetitive play patterns.

Crow_Umbra: brilliant idea given the commanders station ability! Gonna have to try working that one in.

No prob! I love it when Uncommons punch above their rarity weight in the right deck. Best of luck finding a swap, I know things can get into hair-splitting territory with decks like these lol.

Couple Questions/thoughts

Why Koth? he can only fetch basic mountains and you dont have a single basic in the deck. I am not sure the ult or the -3 are good enough with only the dual typed lands. If you want a land centric planeswalker, maybe look at Nissa of shadowed boughs for reanimation, or maybe wrenn and seven for land draw/mass play from hand/big tokens with reach.

Is valakut good enough with only the dual typed lands as well? I know you can scapeshift but given how the deck is laid out, by the time you try a scapeshift combo you will probably already have nearly half of your mountains on the battle field..... I guess maybe if you ran more effects like Dryad of the Ilysian grove to force the land type onto them maybe it could be worth it, but then why not include prismatic omens to give some redundancy so that is a viable combo win?

Speaking of scapeshift, I am surprised you dont have Nahiri's lithoforming. sure its not as good as some of the others, but if you have a way to play lands from graveyard already out (and you have 5 ways) you can just replay the sacrificed lands even if somehow your draw is bad. Just wondering if you had tried this one and didnt like how it played out or if you just hadnt tried it.

and back to the topic of no basics....i know this deck has synergy with self sacrificing lands but running 0 basics? you cant fetch anything if someone uses path to exile on something, or ghost quarters style land removal your glacial/field of the dead, and your totally dead in the water to bloodmoon (or god forbid the merfolk that is blood moon but islands). I think you might be better off cutting a couple of the off color fetch lands for at least a COUPLE basics......like 2 of each.

and you dont run enough basics but if you made a even bigger shift than what i suggested in paragraph above, the new capenna style basic land fetch (Riviteers lookout, etc) while they are ones that enter tapped have exceptional synergies you dont get with the fabled passage/terramorphic expanse style fetches. things like traveling chocobo and ancient greenwarden double trigger it since it is an enters trigger, and since sacrificing the land isnt part of the cost of activation, nor is it a required for the trigger to continue (not IF clause in the middle) you can do things like sac it to your commanders ability with the fetch trigger on the stack, which you cant do with the other types of fetch lands. you can even float mana off them with Urborg or Yavimaya before they go to the grave.

and one last final critisism, you run tiller engine, which is great, but not amulet of vigor or spelunking? something more likely to dodge a board wipe (though i suppose that depends on your playgroup if they are running more mass artifact/enchantment removal).

cgishter: appreciate the input. Will give reasonings behind card choices here. Koth is in here for his -3 and ult. I can still use his +2 and simply not search my library. His ult works with all the non basic mountains in the deck and with the amount of mountains in the deck, 4 damage per is worth it. Same with Valakut. I am very aware there are no basics in the deck and it’s by design which brings me to

Blood Moon and Harbinger of the Seas are pretty much non existent in my group. We don’t run a lot of stax or control decks.

I used to have Nahiri's Lithoforming in the deck but it was weeded out as the weakest link when wanting to run something else.

And I’m running Tiller Engine over Amulet of Vigor not just for the untap effect but the tap down effect as well incase I can swing to take someone out if I can’t win with the landfall and sac effects.

Boardwipes are a part of my group which is why I run a fair amount of recursion in it.

Right now I’ve been pleased with how the deck runs. It’s not a highly competitive deck nor is it meant to be but it can push some crazy damage in a single turn with how the deck is designed to win. I’ve been able to hit the 60 damage mark in a single turn just from sacking and playing lands.

Wow. Definitely got my upvote. Great build here. I've been fine tuning my lands deck for years. I'm going to play test them against each other on here to see who comes out on top! Please give me some feedback whenever you can. Mine is more spell slinger oriented, but similar concept. Here is my lands deck: https://tappedout.net/mtg-decks/20-07-23-land-sacrifice/?cb=1761228567
