I tried this deck out in the trainer, and youre right, it is kind of effective, but it is also very boring...
And I personally think, you could remove the flood from the deck and replace it with something else, perhaps two congeals or a mindflayer and an arctic squid fo fun. Cause there are not many FG, that actually have that many monster out, and FFQ for example doesn even get the chance to fill up her field, cause her FFQs are always frozen and due to the ice shield + SoG, you even woun't get damaged. Couldn't really try out on incarnate, cause the graveyard is bugged, but the worst part on incarnate was his bonewall, and killing 14 of skeletons which are doing little or no damage is exactly the thing you don't wanne do.
havent tried obliterator and graviton, but i can imagine, that they will kick your ass with their momentum creatures..
