It all depends in how many lands you want and how much devotion each spell in your deck has. Each color needs to have at least 11-17 lands producing mana in a 60 card deck. If you want an optimal mana base, you need to have at least 8 to 12 dual lands. How many lands should be in a two color deck? The equation starts at 20% of the format minimum deck size and adds 5% lands for each 0.7 inscrease in the average Mana Value. Here, we use a linear regression having the average Mana Value of the deck as independent parameter. Notice here that it really depends on your deck total Mana value, since when you have small mana value spells, you don't need 4 lands in turn 4, so can build your deck with 30% or less lands. Since you want 4 lands in 10-11 cards, you need at least 40% of your deck to be land.īecause of this 40% rule, a 60 card deck needs to have 24 lands. You draw 7 cards from your initial hand and 3-4 more, so, in total you draw 10-11 cards. Let's say you want to have 4 lands in turn 4. You should have enough lands to play spells in the correct turn.
