The regi-trio vary in their usefulness inthe currentPokemon GOmetagame, but they are still powerful Legendaries that can be put to good use in multiple Battle Raid or PvP fights when players are in a pinch. Because Kyurem will still be featured in 5-star Battle Raids, as well; players may need to hunt around a bit to ensure they find all of the Regi-trio raids they need. Usually during a special weekend like this it is very easy to find the featured Raids, so hopefully that won’t be an issue at all and there will be plenty of raids and encounters to go around throughout each of the special weekends.
As trainers continue working through these amazing events and enjoying the early days of the GO Beyond update, they may want to keep hunting downthe best Unova Pokemon in the gameif improving their Battle Raid rosters and completing their Pokedex is their primary goal.
