“Summer Two-Piece” will be active between the daily rollovers on 19th and 29th June 2020 (UTC). The top prizes include copies of Rhys: Gentle Basker (pictured), the Sorcery Blade 1 and Brazen Spd/Res 1 Sacred Seals, plus 50 lots of Divine Code (Ephemera 6).
The Heroes that can boost your score (and obtain more EXP/SP) are the new Summer versions of Mia (and Masked Marth), Selena, Lute, Joshua and Rhys, plus the regular versions of Mia, Lute and (for absolutely no reason, nuh-uh) Lucina.
The first row of Heroes can be summoned via the “Summer Passing” banner, which arrives on 18th June. Rhys is obviously the freebie, while the remaining three are featured on a Tempest Trials banner, which is around for the same period as the event.
Also, the “Mythic Bug”, relating to Arena and Arena Assault scoring has finally been fixed. Previously, if a team included an in-season Legendary Hero, but an off-season Mythic Hero, players could encounter teams with higher scores than intended, but still obtain a lower score after winning (via Twitter).
