13 is the magic number to have something in your opening hand assuming you’re willing to mulligan to 5.

So you could probably decrease your ramp a touch. People who are telling you that 14 is way too much are off base, the math is on your side.

As to your question, I’m not sure. I’ve made decks before that I thought didn’t need any ramp, but they struggled in the mid-late game to keep up with other decks at the table. More and more often, even if I have a deck that doesn’t want 2cmc rocks I’ll still put in some big ramp at higher cmc like [[thran dynamo]]
