Comments: This isn't exactly an original deck, after perusing what's on here, but I thought I'd post it anyways. My one attempted innovation is trying out Hate for some resource denial early game to slow down defenders from getting more people out. While I don't gain anything from it, they lose out. I saw another Orc deck in a thread using Seduced By Darkness, which may be the better choice, but I wanted to try a Dark Elf card and only have 4 SbDs, and will be using 3 in my Chaos deck. If nothing else, its worth a shot!
