The casual competition will allow trainers to battle with teams including one Legendary Pokémon out of a set of Legendaries not normally allowed in online competitions. The list of Pokémon that players can include one of for this event is: Mewtwo, Lugia, Ho-Oh, Kyogre, Groudon, Rayquaza, Dialga, Palkia, Giratina, Reshiram, Zekrom, Kyurem, Xerneas, Yveltal, Zygarde, Cosmog, Cosmoem, Solgaleo, Lunala, Necrozma, Zacian, Zamazenta, Eternatus, or Calyrex.
Apart from this special rule, the event will otherwise follow Series 8 Regulations with Single Battles.

All participants in this event will be able to receive 50 Battle Points via Mystery Gift once the event has concluded.
