I haven't actually used 1 type consistently and I didnt monitor it. I also switched to unupped sundials by the way.. It really speeds up the deck. (You can always draw, where as sometimes I would be low on light)
It works like a charm on the swarm Gods though. I have played smaller rainbows a LOT and I'd say they are not any better. Those rainbows also suck against strong FGs. The EM chances are good here, in fact. A weakness is seism. If you worry about that, just flick in a few PA. You don't need all the CC's or sundials/horuglasses. It is fun though. I have recently added the 6th CC, pandemonium. Took out another hourglass and it still works.
I built a safer variation of the deck, by the way. It can take an enormous shelling, and it has healing. It is a combo of 3 rainbows I know.
It works like this: Stall. Shield. Plant quinted FFQ. Last turn or so deliver coup the grace with a fractaled golem
You dont even need eternity mostly. So I call it my coup de grace variation. have fun. (You can of course add another golem if you want.)
