I do not see the point in using otyugs in this deck besides eating the malignants when the fill up the entire space, i won't have any malingants if I get rid of the aflatoxin, and eating skeletons wont activate the graveyards.
I'm surprised I didn't think of using hourglasses though, as for equipment: I think an upped dissipation shield would be good, along with maybe a vamp dagger or the owl's eye.
