element is darkness.
supernovas do not work with upgraded vamps. minor vampires will not work as well cause you need special damage amount for epinephrine (see graphic at wiki).
but maybe mark entrophy with minors, supernovas, unstoppable, epi and essence would work. 3 damage got a nice boost by epi so i gotta test that!:)
edit: 5 pillars, supernovas, vamps, 4 cards of each buff and 3 antimatter seems to do really good right now.
