Its card advantage, lifegain, and potentially mana ramp depending on your hand

(Some of them would take up more room than we have in the text box by themselves, but you probably won't control that many lands.) In case you do end up with more than 31 lands, the remaining prime numbers below 100 are 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97
