I was thinking and playing with this idea. Using something like Scaredgirl's rainbow deck. I played around with the deck and squished in a Maxwell's Demon, Anubis, Mind Flayer, FFQ, Lava Golem, and Scavenger(which I later decided against). Most of those cards are pretty situational. I haven't tested it too much yet but running all these can probably give you a whole lot of options. Whichever creature is useless against the particular god can be aflatox'd and then you can proceed to mutate with Druids.
Seems to me that eventually it might work better than boneyard cause you can include more creature variety and still have a use for the ones that don't help against your opponent.
Also, Afla could replace the need for FFQ's as far as creature spam so you have more life quanta to run more Feral Bonds which would would wonders with Malignant spell spam.
Thoughts?
