I havn't found a solid SB yet, but I can definitely say that we don't want Pyrokinesis in a "black meta". Pyrokinesis tends to be quite bad against creature-based decks with discard-spells. Apart from that I think that
Boartusk Liege is a very good choice right now, since its not the range of Abrupt Decay, Punishing Fire,Lightning Bolt and Inquisition of Kozilek AND gives you a nice out on E.Plague. Other viable cardchoices against DRS & friends would be spotremoval in forms of
Dismember and
Swords to Plowshares. For those who are willing to splash black,
Perish should be very attractive right now.
