(According to our data from Cube Cobra, 67% of fixing lands are maindecked on average, but we observed in the prior table that as the density of fixing goes up, the ratio of maindecked fixing does as well.) These numbers are still very rough approximations, but we can draw some safe-enough conclusions about land counts that would, on average, result in constructed-level mana fixing: To emulate two-color Pauper or Standard decks, 60 to 100 fixing lands should be included in 360-card cubes (17%-28%) To emulate two-color Legacy and Modern decks or 3+ color Standard decks, 100 to 140 fixing lands should be included in 360-card cubes (28%-39%) To emulate 3+ color decks in Legacy, Modern, or Historic, 120 to 180 fixing lands should be included in 360-card cubes (33%-50%) That a ton of lands many times more than the 8%-12% included in most cubes on Cube Cobra
