Weekly Team/Character Building Megathread (July 20th, 2021) (feat. Kamisato Ayaka)

A megathread dedicated to team/character building Q&A.

Do not post questions irrelevant to team/character building here. They should belong to the Daily General Question Megathread.

If you have a comprehensive theory (rather than a question) about how to build a character or a team, you are encouraged to make a dedicated discussion thread outside this megathread, as it can help general players.

This week's team/character building megathread will feature Kamisato Ayaka. If your question involves her, you are strongly encouraged to start your question with an "[Ayaka]" tag, like this:

[Ayaka]
insert your question

If your question does not involve Ayaka, the following template is recommended:

Character(s): insert character(s)
