The Ukkos are another way to get Assembly online, as well as roll for another chance at a rookie you can use next turn. We have to run another egg because of it and the Mimi.
The Bancho/Saber ratios are up to you, but Heavy must be at 4.
You can run Liamon instead of LeoX and warp Leo. Both are valid. The DP inheritable is nice and the recovery is great for the Chaos though.
Extra Zubagon for aggression yes, but we need to get bigger than Mother D-Reaper. You can run starter deck Shoto instead of Mimi but it's a little clunky since we don't have a ton of cheap suspension effects, and she will provide some of the aggression that we're going to need to go around the big body.
