I've been tinkering with this thing:

Anything I should change?

I feel like Latts is not gonna benefit from EU what with how stressed she will get. I also feel like with how stressed she will get, she will be easy to outmaneuver. If she can hit, she'll hit like a truck, but if not, she'll be a liability. A maneuverable list will sneak out of Razzi's arc and focus on Manaroo first, then eat apart Latts at leisure, and a harder hitting list will try to just outhit you, so it'll be a gamble. That being said, I see a lot of potential, especially if you surprise them early on with a couple vicious volleys, or use Latts creatively to make the most of Manaroo's 360 arc.
