Card Guides
Sol Ring first, then Arcane Signet, then the green land-fetch spells that fix your colors on the way. The staples worth knowing by name.
Artifacts and lands that don't care what colors your deck is, which is why they show up in nearly every decklist regardless of identity.
Sol Ring ↗
Turn one, doubles your mana instantly. The best ramp card in the format, in any deck that can cast it.
Arcane Signet ↗
Two mana, taps for any color your commander's identity includes. Close to a free include everywhere.
Command Tower ↗
A land that taps for any color in your commander's identity. Essentially a free include in any deck that isn't mono-colored.
Green's specialty: fetch a land straight to the battlefield, fixing color and ramping at the same time.
Rampant Growth ↗
Two mana, fetches a basic to the battlefield tapped. The standard shape of green ramp.
Nature's Lore ↗
Same effect as Rampant Growth, but the land enters untapped, which makes it strictly better in a green deck.
Farseek ↗
Fetches a nonbasic land type instead of just a Forest, which makes it real color fixing in a multicolor deck.
Slower, but worth more than a straight mana boost once they're down.
Sol Ring, and it isn't close. Turn-one Sol Ring effectively doubles your mana on turn two, which is a bigger tempo swing than almost anything else at any price point, and it's legal and affordable in every Commander deck that can cast it.
They do different jobs. Land-fetch spells like Nature's Lore are safer against artifact removal since they put a nonartifact permanent on the battlefield, but they're slower to pay off since a land doesn't tap for extra mana the way a rock does. Most good decks run a mix of both.
8 to 12 pieces is the target for most decks, see how much ramp to run for the full breakdown and how the number moves by archetype.
No, but a strong ramp package (8+ pieces) does let you safely trim a land or two. See how many lands to run for the tradeoff.
The Deck Lab flags whether your ramp is keeping pace with your top end, as you build.
