Well, I'd see what others had to say... Duos can either come or go, but, I read the comments and seem to be under the impression that most are bad.
But, I also agree with TimHobbit that Totem either needs to just bite the bullet and do a trio card. Or, if they're to chicken- to just get rid of the option. It gives me false hope that there is a three-some card every time that I see it! :(
