Theorycrafting for using ultimates at Red/Blue Wyvern maps

I think Red Wyverns are better in most cases. I trained through half of 9x by killing the bottom platform while a Bishop rotated Genesis from the second to top platform and the third to top platform, taking out the entire map. By freezing the bottom left, I also made it possible for the Bishop to hit that platform. I dunno how you would handle Blue Wyverns.
