Lord Slitherspear confused me quite a bit. Then I checked the hearthpwn's heroic decks for it and saw a priest full of silences. So I just thought I'd make it an even more solid cheap deck, and that's exactly what you're seeing.
So bye bye to Circle of Healing and hello Lightspawn. A way easier target for the buffs and an extra guy for the OTK. Do buff Deathlord though because it's a good way to remove minions without having to trade. Lightwells will heal him.
