Well, I think a good number of people use some variant of CC Why Bother, which would somewhat wreck this god. Quinted destroyers aren't affected by CC and can build damage pretty fast. FFQ, fractal, and/or air nymph get through bone wall, whichever ones the deck use. Pulverizer kills inundation, stopping condors from growing, while permafrost blocks all skeletons. Antimatter or freezing deals with any big condors, so physalias are the only threat. But with antimatter + shards + fast damage, the poison will probably be heal-able until the god dies.
Most other rainbows also have permafrost, along with bone wall, which would only benefit from skeleton deaths. They also have permanent control, which stops inundation.
On the other hand, inundation + plague pretty much destroys RoL/Hope, and growing condors, left un-lobo'ed, can get over hope anyway.
So. Rainbow > Deluge > RoL/Hope.
