Scouting banners rotate weekly based on units. If a scouting banner features a member of that day's unit as a 5★ or 4★, the banner will appear on that unit's day. All cards associated with that banner are scoutable.
For examples, on RYUSEITAI's day the Hot-blooded Tough Guy scout will appear, as Chiaki is a 4★ in that banner. In addition to the 4★ Chiaki, all cards from the Hot-Blooded Tough Guy banner (the 5★ Kuro, 3★ Tetora, and 3★ Midori) are scoutable from that banner.
