If my pandora team can steamroll twinlits then your Andromeda team could do likewise.
The trick is:
Use a team with at least 10 water attributes with as many orb changers as possible (fast orb changers like Sieg/Reine/Kamui/Hatsume are great here)
match a row on floor 1, clearing everything.
Next floor, match 5 orbs for mass attacks twice, clears everything. Don't waste resources trying to break their defenses, it's not worth it.
Floor 3, try to do mass attacks consistently. 5 turns is more than enough; use Andromeda to unbind if needed.
Floor 4, just fuckin unload on them. An orb/type/attribute enhancer is great here.
My Twinlit team is Pandora/Haku/Hanzo/Vamp/DMeta, and it is foolproof. I have tested it dozens upon dozens of times.
Looking at your padherder, make yours Andromeda/Skuld/Reine/Nut or Kamui or Siegfried/Hera-Is or Wadatsumi. It's uh, really quite a bit better than my team since you have three hypermaxes there.
