Dunno about the rest of the deck, but imo 1-2 deflags is a must. No PC= a dimshield can beat us. Do we want that chance?
Also, games are best of one. They could try to go for a straight-up rush, disregarding anything else, and trying to out-speed the rainbow deck. Even then, they could use, say, a fog, that also pretty much halves our damage output.
