Weekly Team/Character Building Megathread (Jan 1st, 2025) (feat. Mavuika and Citlali)

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 Mavuika and Citlali. If your question involves them, you are strongly encouraged to start your question with a "[Mavuika]" or "[Citlali]" tag, like this:

[Mavuika]
insert your question

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

Character(s): insert character(s)
insert your question
