@Mega gk Damage dealers that can do a bit of support are quite good though. For the Asterios Super Recollection Quest, I used a team of Galatea, Reines and Castoria. Reines and Castoria provide the quasi-permanent solemn defense, but a little bit of damage can still get through if you don't play perfectly. That's when Galatea's party-wide heal shines.
Talking about Jacques herself, I think she's a really powerful unit that suffers from unfavorable environment. Quick is simply inferior to the two other cards. Buster is better for farming and Arts is more reliable for longer fights. So, despite Jacques' amazing skillset, and I do want to enphasize the word AMAZING, she does get outclassed by the competition.
Still hot AF though and that's all the reason you need to roll.
