I feel like the whole point of Galaxy 2 was to shake out the remaining ideas they had after Galaxy 1.
I can't imagine what a Galaxy 3 would even do that Galaxy 1/2, 3D World and Odyssey didn't already do.

I feel like cutting Megalo to 2 copies
It has a draw and last ditch Astero mill effect with Ground Xeno but it's mostly just used for Stego's swarm effect. Maybe I'll replace one with Gallim instead so I can skip straight to the level 6 Synchro without Velphito. Actually, maybe I could even replace all 3 Megalos with 2 Gallim and cut off Velphito for an extra ED space
