Many players copy decks without thinking about the manabase much, and primarily focus on if they should change any spells or sideboard cards. It's easy for manabases to be overlooked. But mana is how you cast your spells, and if you aren't tweaking the lands you use, you're dooming your deck to be sub-optimal.

If you like building or tuning decks, here are some tips for developing your manabase.

Considering the Format

Certain formats are going to give you a wider selection of options than others. In some ways you would think that having more lands to choose from would make building your manabase more difficult, but this often isn't the case. For instance, once you get to Legacy or Vintage dual lands get thrown into the mix, which are basically just straight upgrades to other lands that produce two colors of mana, like the Ravnica shock lands.

In Standard there are not that many nonbasic lands to choose from. This means it's harder to build a deck with lots of colors, because splashing isn't as easy. In formats that have fetch lands, like Modern, it becomes easier to build successful three-color manabases. While three-color manabases still exist in Standard they aren't going to operate as smoothly, and you'll have to play more lands that come into play tapped.

In Standard you often have to play any on-color lands that produce two colors of mana in your colors, even if those lands are far from perfect. Take a look at the Dimir Rogues deck I took to the Top 8 of the 2020 Season Grand Finals.

Rogues lists have certainly changed since this tournament, but I'm focusing on the manabase. There aren't many options for blue-black dual lands. I could have played Fabled Passage of course, but in a deck like this that often needs double black and double blue early in the game, you want a land that can produce one of each color. The options are scarce.

Temple of Deceit and Clearwater Pathway both have issues. One comes into play tapped, and while the other does provide flexibility, it still can be a problem to play it early on and choose the wrong side to play it as.

In some ways the best of the options is actually Zagoth Triome. It may be surprising to see a three-color Triome in a two-color deck, but it produces both of the deck's colors, while being able to cycle later in the game.

Most importantly, it's a Swamp.

Castle Locthwain is an incredibly powerful land, but you have to do some work in order to play it untapped.

Whether or not to play a utility land like Castle Locthwain is an interesting decision. You can always get screwed one way or the other. There will be players who have to play the Castle tapped on a key turn and cut it from their deck without a second thought. However, once you start drawing a bunch of cards off it, you realize the power behind having utility lands that don't just produce mana. It's a very delicate balancing act.

Deciding How Many Lands to Play

I am known for playing fewer land than other players, but it's a risk I like to take because spells are so important. The game is called "Magic," after all. Adding just one additional spell to your deck can make a major difference.

The conventional wisdom is that a 60-card deck should play around 24 lands. Of course, many successful decks play as few as 20, or as many as 30, and there are even decks that go beyond these extremes. Here are the factors to consider when you're deciding whether to stray from 24.

Mana Curve

The cheaper your cards are, the fewer lands you want to play. Decks with lots of inexpensive cards are almost always aggressive decks or quick combo strategies, with very little to do with extra mana if the game goes long.

Cantrips

If you play lots of spells that say "draw a card," that's another reason to play fewer lands. Every card whose primary purpose is to draw into another card essentially makes your deck thinner. If you could put 20 copies of Street Wraith in your 60-card deck, you'd essentially be playing a 40-card deck. That makes playing as few as 17 lands fairly reasonable.

Lots of cards act as cantrips. Ponder is a classic example, but so are cards that cycle. Even something like Light Up the Stage that digs you deeper into your deck is a cantrip.

Not everything that looks like a cantrip will help you hit your land drops. For example, Shark Typhoon is definitely different from Street Wraith or Mishra's Bauble. The latter are cards that you aggressively and immediately use to cycle and draw a card as early as turn one. You usually won't cycle Shark Typhoon until later in the game, so it isn't going to find you lands early in the game as easily, and therefore provides less value toward lowering your land count.

If I can reliably cast a cantrip early in the game, I count about every three or four cantrips as enough to cut a land. If it's a late-game cantrip, I might use it as a reason to cut one more land at the end of a deck building process, if I'm on the fence on the correct number of lands.

Draw Cards

To a lesser extent, anything that draws you cards can be considered a way to hit land drops, and is a reason to play fewer lands to prevent late-game flooding. It depends what the cards in question are. A classic example is Divination—I feel like a deck with lots of Divination-like effects wants one fewer land most of the time.

Ways to Use Extra Lands

If you have things to do with your mana late in games, then it's generally okay to have a bit more mana in your deck.

Cycle lands are a great example of a way to cash in your lands when you don't need them. Other cards that make me okay with having more lands are discard effects. If I can discard excess lands I don't need later on that's one way to make use out of them, but there are plenty of other ways too.

In Four-Color Control, extra lands can trigger Omnath, Locus of Creation landfall, create a Zombie with Field of the Dead, or allow you to recast a spell if Wrenn and Six used their ultimate ability. For these reasons (and others), it's perfectly reasonable for the deck to play 29 lands.

Modal Double-Faced Cards

If you count the new cycle of spells that can also be played as lands as strictly lands, then you can afford to have more lands in your deck. These make it less likely you'll get mana screwed, since they can be either more lands or more spells depending on what your draw requires. I often consider these lands about 3/4 of a "real land" when deciding how many lands to put in my deck.

Cards that Search Up Lands

These are cards that make me want to play fewer actual lands in my deck. You are relying on naturally drawing two or three lands to cast these, but then you want to be able to find extra lands with these, to bridge the gap into the later turns of the game.

I like to cut about one land for every two copies of The Birth of Meletis or Cultivate I put in my deck. However, you want to keep a minimal amount of lands to be able to cast these cards, so I would never go below 22 total lands in ramp-style decks, and really want to be in that 23-25 range for most 60 card decks that are midrange/ramp.

Fetch Lands

While I don't weigh this effect very heavily, the more fetch lands you put in your deck, the more deck thinning you are able to do. This is a great way of preventing drawing lands later in the game.

Balancing Your Colors

Ahh, if only it were as easy as making sure your manabase had an equal number of sources of every color in your deck. Unfortunately, this is rarely enough. Often you will want to play more sources of one color, and less of another.

Two key factors go into this decision.

What Turn You Need Each Color

In Pioneer, we often see decks prioritize casting Elvish Mystic or Llanowar Elves on turn one. Here you are looking for lands that can be put into play untapped on turn one.

If a land is tapped for two or more mana, it produces {C} instead of any other type and amount.

Buy This Card! https://shop.tcgplayer.com/magic/dominaria/damping-sphere

For this purpose, it becomes important to further narrow the lands you look at beyond just what color they may produce. I want a minimum of 15 untapped green lands for turn one in these decks, but would push toward 18 untapped green sources if at all possible.

If a color isn't needed until the later turns, you don't need as many sources. In addition, if the deck has some card filtering you need even fewer sources. A good example is a blue-based control deck that splashes for Blood Moon, with cantrips like Opt.

Opt lets you dig deeper into your deck. In this case, it's safe to lean harder into blue so you can cast Opt on turn one. With the extra digging, you're still likely to find a single red source in time for Blood Moon, even if you have far more blue sources than red sources.

The Color Demands of Your Spells

Cards that cost two (or more) mana of a single color require that you play more lands of that color. This is especially true if you intend to cast the card early.

In order for Anger of the Gods to work as a red board wipe, you want to cast it as early as possible—usually turn three. That means you need two red sources in the first three turns of the game. I often look for 18 or more mana sources of a color if I'm playing early game spells that require two mana of that color.

Colored mana sources aren't always obvious. In a format like Modern, it becomes important to look at how many fetch lands you are playing.

If I'm playing a deck with Birds of Paradise I can count it as about half a land toward producing a mana to cast nongreen spells.

There's always more to learn about building manabases, but you now have a framework for how to evaluate your deck's mana and start making adjustments. Good luck!
