I know we already had the Fighting tera used but I think it'd have been cute if normal decidueye was using its hisuian associated tera (likewise for eventual Typhlosion and Samurott 7* raids)After the past unique and thematic tera type choices like Dragon Charizard, Fighting Cinderace, Poison Greninja, and Water Pikachu, the choice of Flying Decidueye makes sense but still stands out in a mundane way because you can just get it naturally whenever you hatch a Rowlet. I guess the point is to not use STAB, but I think giving it a Ghost tera type would have been more interesting and something you would have to spend shards on otherwise. I guess we'll see what gamefreak has planned against Miraidon for an Electric-weak raid without an immunity.
