What the published guide says
The source highlights Story usefulness and magic damage. Its important team caveat is the lack of a Commander buff, not a claim that Commander and Super Bro can never appear in the same lineup.
This is a September 24 published-opinion snapshot, reviewed here on September 25. A later patch can change its usefulness. The official experience description does not provide a full stat sheet.
The opportunity cost of a slot
Compare what the support slot contributes to your actual damage core. A lineup can contain several damage types, but one support interaction should not be credited to units that do not receive it.
Keep the map, difficulty and rest of the lineup consistent when comparing. Watch the wave or enemy that previously caused the problem. If you change the damage core, support and economy at once, the result will not tell you which change mattered.
Before you commit scarce resources
Inspect the exact unit variant in your inventory, its current stats and any available upgrade or evolution conditions. A source ranking does not establish that your version is fully upgraded or that another player's build can be copied without its support setup.
