I am playing a mixed objectives/aggro deck, with around 1/3 of the ploys and upgrades focused on moving to objectives, swapping them, shadcaller, etc. and the same amount of ploys and upgrades for aggresive playstyle. I try to inspire Grimnir and Tefk in the first turn, and usually leave Mad Maegrim forgotten in the rear to score the keys or another hold objective card that I may get. I found the darts very useful, because bad positioning from your side (or a wise move form your opponent) can leave an uninspired duardin (Vol and Mad) out of the fight way too easily. It may feel overkill, but I think activated runes with flickering image (and maybe also the darts) will make Mad a force to be reckoned with when facing skavens and SG. I have two friends playing these two bands, if I ever pull it out I will let you know
