[Touhou LostWord] vs A6 Lyrica DS - Lv120 clear! (Purple Heart Only)

Combat starts at 0:00. Character set-up at 2:33.
Apologies for going rather quickly, this stage was draining my patience bit by bit and I was at it for about an hour. Let's just say it's a bit annoying to get accuracy checked if your accuracy buffs are cleaned off after every gauge break.
At least the Prismrivers seem to have put up a good show for us. They only look bad here because I didn't upload the 1+ hour concert of them curbstomping our team.

I should not but, to solve G2 RNG issue (if you have the units ofc) replace Sunny with B3 Eiki, she can go without sticks, just put Lunar Capital Stasis Plan on her LW or Physician Assistants, for G3 replace F1 Reimu with L80 Reisen or L80 Remilia or any other unit not nerfed at 120 which are just two and should be B3 Yorihime and B3 Seiran with FR.

[@countesstimpani8233]

- I dont have B3 eiki sadly. Am hoping kourindou wheel will bless me.
- And to be fair, your G3 suggestion will probably work better.
