Besides Lichling and Warmandrils nothing comes to mind. Important to note that on release, you could run 3 of most (if not all?) of the Pack Mentality Kanens. Nothing with 4.
I think they should add back the multitude and unique abilities. It made it a lot easier to search out deck limits on Poxbase. Also, it made it much more apparent that there was a different deck limit than the average rune (besides looking at that small, easily missed number).
