Not saying this is reasonable to expect, and this team went 35-0 for a reason, but here is a comparison of Bard's team averages to my J&W team that sold out on Ath/Def. We ran Flex/Press. I think Bard would be a lot better if you took just 5-10 points of that Ath/Def and spread it around. Also agree M2M would be better for them.
Disclaimer: individual players matter more than team averages, but the averages can be useful to compare. I felt at the time that J&W was paper thin--had just enough--at everything but Ath/Spd/Def and Bard is clearly lacking in some of those.
