Team Light ran a Titsader and Vadersader and looked at Arsesader and Eyesader this past war. I tested a Staffsader, but it did not make the cut for our final vault. It healed like crazy once it got going, but its speed and damage output were unimpressive (and we did not have any other good synergies, but that is a War issue). Eyesader made it, but was converted prior to round 1. I liked that deck.
I have used Hammersader and Bowsader for my arena decks before. They did better than I would have expected.
In short, you can make a lot of cool decks with Crusaders, and the
one was a lot of fun to play.
