About a week ago I was trying to make an adjustment for the eldrazi MU. I was in between adding a goyf back to the main deck or just straight up adding a dismember. I was going to shave an abrupt decay for either card (go from 4 -> 3). Someone earlier suggest Hornet's Nest (also zenithable). I considered playing retribution of the meek (though eventually I settled on dismember since its instant, then never got paired against it). Ultimately I think we may be better off not running random 1 off cards in our main deck for a match up we might face.
I think we just have to hope that they don't have a super explosive draw. It sucks but, sometimes your opponent just "has it". I think our average draw is better than theirs and any specific cards for the MU should be in the sideboard.
