Graveyard might be better as boneyard, less cost unless you're really worried about TStorm. I like to get my 'yard out as soon as possible, but also like to have quanta left to play the wall if needed. Many times with larger rainbow decks I also seem to have way less death quanta than I really could use at the time. Also, by the time you start getting skellies, you should be mutating them anyways, so 1/1 vs. 2/2 doesn't really matter much
I also personally like having two FFQ, just because she seems to be the most targeted card, and I use two Quints for an Oty and usually the Druid, so FFQ usually has to just weather the storm on her own. Her synergy with 'yard and Druid, however, makes her a major player in this deck oftentimes
