there's not even any good black removal in FFF available
I don't think you could even build a bob deck with it legal in FFF as by far the most efficient draw engine, because with no critical mass of 1/2 drops bob is going to fucking kill you.
maybe if you built a low curve around a sacrifice creature shell with infestation sage + eaten alive + gatekeeper of malakir, since you can sacrifice your own bob and gain back life through cecil

Just imagine how much better this format would be than the trash we have now
