Whoops, I forgot that there were two main methods of minimizing AS usage xD (reliance on skills, which isn't a 100% guarantee, and a 100% guarantee by ignoring skills) So I guess the spirit efficiency is mainly for the 100% guarantee method.

Though with what I was saying in the parentheses, I just meant that you don't have to keep every card you get (because I remembered this line from your blog: "Never fused away those 3 Stars daemon attack booster. They are useful in minimizing the usage of AS in climbing tower example, Faith.") since for some of them, there's no point xD I should have expanded on that, oops. There are multiple things to look at when determining cards to keep, such as spirit efficiency, which was what I was focusing on with that Flame Sprite vs. Gregory example xD;
