Unspeakable Symbol is the first come to mind, and Durable Handicraft allows easy counter when your creatures enters battlefield. Of course, if you like artifact creatures, modular mechanics would function just fine. I personally favors simic Graft mechanic myself, since they grant abilities to all of your creatures with +1/+1 counters.
I'd recommend Necrotic Ooze for this deck, since you could put a counter on it to give Volrath all abilities of creatures in every grave.
