This is the equivalence of dragons in my trusty Darkness/Death deck. Actually, it's already better than dragons. Remember that with a few Boneyards out, you can kill over, and over, and over, and over again (kill something (an enemy or your own virus) ---> three skeleton for you ---> kill your own skeletons ---> a couple of 4/5 vultures in a single turn). And that's, like the previous post stated, not looking at the fact that I have a massive Bone Wall up, several more in my hands along with a steal or two, and a field of Parasites and skeletons that are more punishing for the opponent to kill than to let live (well.. un-live / live... whatever.)
I did vote for +1 HP to start off, though... but that's just personal greed =9 I could always just pack a Nightfall instead.
