To be clear, I've been playing paper Magic for almost 30 years; I know how many lands I need for a paper deck. I know how many lands I need for a deck that's well-randomized by proper shuffling. How many lands do I need for a deck on MTGArena?. How many lands should be in my deck? You should have enough lands to play spells in the correct turn. Let's say you want to have 4 lands in turn 4. You draw 7 cards from your initial hand and 3-4 more, so, in total you draw 10-11 cards. Since you want 4 lands in 10-11 cards, you need at least 40% of your deck to be land. Because of this 40% rule, a 60 card deck needs to have 24 lands. Notice.
Although many lands generate specific colors of mana, lands are colorless on their own. Flavor Brady Dommermuth explained the flavor behind the playing of lands in a Magic duel: [5] The basic idea is that a mage must first create a bond to the land through some kind of ritual. Whether the mage needs to visit the land is an open question.. Lands represent locations under the player's control, most of which have mana abilities.[1] They are the fundamental form of fuel for the gameplay of Magic, and because mana is needed to use almost any card or ability, most decks need a high proportion of mana-producing lands (typically between 33-50% of the total deck) to function effectively.[2] It will often be the most.
