what are some good ways ways to determine how much land should be in a magic deck?

You need to figure out what the mana curve is on the other cards in your deck is to decide how much land to put in a deck.

The general baseline is 24 land. Depending on the mana curve of your cards, that can go higher or lower. Another guideline is that for every two non-land cards that can produce mana or fetch land, you take out one land.
