We kinda have to wait and see what else Katana get from the new set, but running more than 3 is a bit risky when stuff like Magic World, Non-Iblis Danger World, and general Soulguard-less monsters are attacking.

With that said, yes, running more than 2 might be the new go-to way. And please specifiy "would you run more copies" next time, so I can understand the comment correctly. Sorry.
