I'm a newb to this deck (board as well, but I've taken an interest in playing WGD lately) but I was just wondering if Demonic Consultation has ever been considered for WGD? Seems like it could be good, but I'm guessing it's inferior to another card in some way since it hasn't been included in a single build I've seen.

Also, can someone explain to me the singleton Mulldrifter? I've seen it in a few builds but it kinda seems a little out of place to me, like it could be replaced by something more useful? Thanks!
