Let's see what upped cards you have and go from there. 3 Rols. You could upgrade 3 more and go for rol/hope without the lobos. It'd be weaker, but it'll still work. You have 3 upped graboids. You could go for the old fashioned graboid rush. You'd be surprised at how effective upped graboids can be. I'd personally recommend upping supernovas. They improve dramatically when upgraded, and a rainbow with only 6 SNs is pretty powerful. Couple that with your upped arsenic, oty, druid, grabbies, crusader, hourglass, and you have a neat little rainbow in your hands.
