Strip Mine, Boseiju and Bojuka Bog for lands that do more than produce mana, with the color, tempo and opportunity costs made clear.
Lands that do more than produce mana, with the tradeoff that makes the utility worth the slot.
An answer to a specific problem, held in reserve until you need it.
Bojuka Bog ↗
Enters tapped, but exiles a target player's graveyard the moment it does. A real answer to reanimator or recursion strategies that costs a land slot instead of a spell slot.
Boseiju, Who Endures ↗
A land the vast majority of the time, and an instant-speed answer to an artifact, enchantment or nonbasic land through channel. It has a very low opportunity cost in green decks that can support it, though it is legendary, nonbasic, and still has to fit the deck's color needs.
For pure utility beyond mana, Boseiju, Who Endures is one of the strongest options in a green deck that can support it. Its opportunity cost is low because it is usually a land, but its legendary and nonbasic status, plus the colors your deck needs, still matter. Command Tower is excellent fixing, but it belongs in a mana-base discussion rather than this utility-land list.
Sometimes. A land that enters tapped or produces only colorless mana can cost real tempo or make your colors less reliable. Run one when its utility is likely to matter and your mana base can absorb that cost.
It's one of the most efficient places to put it. Bojuka Bog answers a graveyard strategy without spending a spell slot on an effect you might not need every game, at the cost of entering tapped.
There's no fixed number, since it depends on how much utility your land count can afford to spend on effects instead of raw fixing. See how many lands to run and the land and mana base guide for the tradeoffs.
The Deck Lab flags a mana base that's too thin for your curve while you're still building.
