A useful Update 4 roster snapshot
The roster table is designed for the question players ask first: what is this new unit, what class does it belong to, and where does it come from? It includes Boundless, Secret, Unrivaled, Exclusive, and Mythical additions from Update 4.0, plus the element used in current coverage.
The official trailer announces more than 24 new units, while the two current lists overlap on 21 names. That makes this a practical Update 4 directory rather than a claim that every new unit has already been identified.
Use acquisition routes to plan the next run
Banner units, Summer Capsule units, extraction rewards, locked-room drops, raid rewards, legend-stage rewards, and evolution targets ask for different preparation. Filter the table mentally by the route you can access now instead of chasing every name at once.
The element column is a compact way to compare additions while you are learning the current roster. It is not a damage ranking. For a team decision, test a unit in the mode you are actually playing and keep an eye on new update notes.
