Who should I make into their 3rd form? Among the Super Rares

I think hopping is the priority first. Considering Esthe, Mermaid, Jura, and Future chapters, I'd go with Probe and Surfer. Super rares can wait, I think.

What stage are you currently攻略ing? If it's around the Future or Cosmic chapters, I'd recommend Super Rare units effective against Aliens! For example, units like Bolt or Merara.

Show me your characters

Probably around the Pixies, I'd say.

It's still nya, right? (pressure)
