You want to look at soldier count. If an hn card has more soldiers than an r, keep it until you can replace it. Tbh, if you are active and in an active alliance, you won't be using n cards for long. Or even r for that matter. I remember starting with rose mage and before I could finish evolving it, I had replaced it with stronger cards.
