Why isn't either Wasteland or Strip Mine in this list if Dust Bowl is?

I chose to not include cards that can only be used to get rid of a single non-basic, so Dust Bowl's ability to sacrifice land after land to continue to destroy non-basic lands is what puts it squarely into this list.

Helldozer?

Helldozer was initially dismissed, but being able to pay to destroy two lands because the first one was nonbasic makes this work for this list.

Imagine getting a bunch of black mana from Urborg, Tomb of Yawgmoth plus Cabal Coffers plus Thespian's Stage plus Vesuva plus Nykthos, Shrine to Nyx plus Deserted Temple and then dumping that mana all into Helldozer... The salt would be unreal.

What about something like Nature's Wrath or does that go against your criteria?

mazrimtaim, Nature's Wrath and cards like it don't really punish greedy multicolored decks. Basically, I would rather be playing a Dimir deck rather than Mono-Blue or Mono-Black against Nature's Wrath because of the fact that I'll be playing more nonbasic lands that aren't islands or swamps than multicolored spells, which means it hurts multicolored decks less.

Blood Sun for sure.

Dreno33, with the exception of fetchlands, Blood Sun only shuts down utility lands, not colorfixing lands.

even if it only shut down fetchlands that is plenty reason to use it as a gold hate card, especially since it redraws. your weird limitations take away from showcasing very viable options for players. i think in the ramp one you don't allow mana vault because you have to pay to untap. that's crazy.

fyi, people would run Blood Sun over Ore Gorger every time.... it's not even gold hate. it's just land hate. the amount of people that run arcane decks is so minimal that suggestion serves very little purpose. To exclude Blood Sun for your reasoning is just annoying since new players will take your "guides" as gold in the beginning.

I see where you are coming from, I really do. My limitations however, are my best approximations to the types of cards that will reliably have an impact in the deck's respective goals (although sometimes, they require being in a specific archetype of deck).

Blood Sun is a great card, because it shuts down utility lands and fetchlands, but it is not a great anti-gold card. According to https://edhrec.com/top/lands, there are quite a few cycles of lands that are more played than fetchlands: shocklands, checklands, karoolands, scrylands, painlands, tangolands, lifelands, and even guildgates, not to mention the 3-colored lands or lands outside of cycles. Not a single fetchland appears in the top 100 lands. I think, therefore, it's not unfair or "weird" to say that it does not successfully work as a gold-hate card. (I do think it's a great card though, and I might make another list for ones that shut down utility lands. Think of it like The Immortal Sun, which is not good enough ramp to be considered a "good" ramp card, but has decent enough draw ability to find a spot on my list of cards that steadily draw.)

Mana Vault and other cards like it are ways to gain a lot of mana for a low cost. In a way, they are like a Dark Ritual that can be reused on turns. They are very powerful for games that involve players throwing politics to the wind in order to win before their opponents can stop them, even though they could be banded together. However, this is obviously not representative of the majority of games or playgroups. In that way, I do believe that choosing to play it instead of another ramp card is lowering the number of ramp cards in one's deck.

Do I believe that Ore Gorger is a card most people should run? Absolutely not! And I never implied that either. But, in a spirit tribal deck with red, will it affect players towards running more basics? Undoubtedly.

To exclude Blood Sun for my reasoning is just helpful, especially for new players who might not understand the fact that it is not an effect gold-hate card.

Naked Singularity perhaps?

TheDeckMaker2300, unfortunately, Naked Singularity can only be played in five-color decks. Besides, it's more effective against monocolored decks since their lands would be guaranteed to be making the wrong color of mana, whereas the more colors you have, the more lands you could have that could make a color you need.

Have you considered cards like Ravnica at War? It doesn't affect non-basics, but it does give a major boost to mono-white decks playing multi-color opponents.

Hemalurgical, unfortunately, multicolored permanents are not that common in commander. According to EDHREC, the most popular multicolored permanent in the format is Mirari's Wake, and it's only played in 25% of decks that could play it. In other words, most multicolored decks are filled mostly with monocolored cards.
