I think ther's a lot of pilars....a 40-50 cards deck may have 10-15 pilars....so just remove some of they!
you can also remove 1 otyugh, firefly queen and one emphatic bond to be a lighter deck..
add some nova-supernova can also improve the speed (and so removing other pilars...)
I can also suggest you the combo (alwais it) with otyugh+bonewall for an "indestructible" shield
P.S. for me vampire stiletto and stone skin are useless in this deck
