Risk was mitigated with a ten-year commitment from Schreiber Foods, the seller and now the number one customer of the spun-off printing operation (see The Target Report March 2014)
Otherwise, I love the scalability of caring about the number of creatures in your graveyard
Malakir Bloodwitch I own a few foils from before VOW was printed, and I bought in at much too high a price
I cut Dauthi Voidwalker, Mai, Scornful Striker, and Phyrexian Obliterator for four copies of The Rack, the usual suspects of silver bullet artifacts, and a couple of copies of Nethergoyf to give us another potential threat
While obvious at this point, I think it's still worth pointing out
In any case, that leaves you with a 12/12 trample way ahead of schedule
