Mono-color mana bases look simple and hide real decisions. With no fixing needed, every nonbasic slot is a choice between a basic that always enters untapped and a utility land that does something extra. The discipline is count: run enough basics that your cost-reduction and basic-matters cards work, add utility lands that serve the deck's actual plan, and treat colorless utility as nearly free — a mono-color deck can absorb several colorless lands before its coloured spells start suffering, but 'several' is a number to test, not a licence to run them all.
Real lands discussed here
Cabal Stronghold (Land; rarity: rare; most recent printing listed by Scryfall: Dominaria): {T}: Add {C}.
{3}, {T}: Add {B} for each basic Swamp you control. Snow-Covered Swamp (Basic Snow Land — Swamp; rarity: common; most recent printing listed by Scryfall: Kaldheim): ({T}: Add {B}.) High Market (Land; rarity: rare; most recent printing listed by Scryfall: Secrets of Strixhaven Commander): {T}: Add {C}.
{T}, Sacrifice a creature: You gain 1 life.

Putting it into practice
Every slot should argue for itself against the card it replaced. Test a new inclusion through the deck's normal sequence — early development, mid-game pressure, late-game closing — and notice where it helps and where it sits dead. Cards that only shine in the best case are the first cuts when a proven role-player needs the slot back.

The bottom line
Tune in small steps. Change two or three cards at a time, play several games, and write down what actually happened rather than what you hoped would happen. A list adjusted on evidence converges on its best version; a list rebuilt after every loss never stays still long enough to be judged.
Build your mana base on purpose, count it on paper, and test it in real games — and when you want a starting list that respects both your colours and your budget, the MTGBrew AI deck builder treats both as hard rules.
