-1 carbuncle. consider +1 terraforming. switch out the fields for advanced darkness. in order to play this deck the fastest way possible you need to do what's needed to pull rainbow dragon out, that means getting crystal beasts to the field OR grave which is where advanced dark comes into play, focus on the traps that send to the grave and pull rainbow dragon aka rainbow gravity and rainbow path. i recommend at least 1 hamon, lord of striking thunder. finally, i personally feel you should play triple rainbow dragon, but that's your call. now this is how to focus on power and using rainbow dragon which is how i typically go about it, however you can also just focus on an xyz build version that focuses on manipulating carbuncle.
