There are two extreme possibilities for using Graveborne Muse. The first is in a deck comprised primarily of zombies. It will cause you to draw many cards and to lose a lot of life. The second is in a deck with no other zombies, basically as a replacement for Phyrexian Arena, but attached to a 3/3 creature. I suspect that the 'optimal' use of this card lies somewhere between the two extrema, probably somewhat closer to the 'Phyrexian Arena' situation. How many other zombies should be in the deck then? Four seems too few, but eight seems just a shade too high. I would probably aim for six or seven other zombie cards, consisting of two or three different zombie cards. Which zombies should be used and in what quantities depends, I think, on the aims of the rest of the deck. An aggressive deck intending to use zombies as its finisher might choose to use Undead Warchief and Mass of Ghouls. A controlling deck might prefer Withered Wretch, Boneknitter, and Cabal Interrogator. I didn't make this a "Let's Break..." article because I really have no idea where I'd like to go with Graveborne Muse. I just wanted to prompt some discussion about what sort of decks people think are positioned to use it most effectively.
