Here's a thought: drop both FFQ and quint, and then use Eternity and Mindgate as was suggested to get a creature to play and bounce each turn. The only problem is that makes the damage potential wildly variable.
Also, I got an interesting suggestion via PM- adding a nymph's tears to force my opponent to have a creature I can afflatoxin. (Great vs people with only immortal creatures i.e. DG) Unfortunately, tears are pretty expensive, but it's an interesting idea nonetheless.
Oh well, I don't really have time to tweak the deck right now, but I'll definitely think about it some...
