• ▸ Introduces two new types: Aural (sound/wave-based) and Astral (space-themed) Aural-type is a special type that focuses primarily on sound waves but also extends to include other types of inaudible waves. Moves like UPROAR, GROWL, and SONICBOOM are Aural-type, of course, but so are moves like FOCUS BLAST, AURA SPHERE, and VACUUM WAVE. Astral-type is a special type that focuses on Pokemon from “out-of-town.” This type is very rare, and it’s worth going out of your way to catch some of these Pokemon. MOONBLAST, METEOR BEAM, and SWIFT are some examples of Astral-type moves.
• ▸ Dragon-type is now physical, buffing classic Pokémon like Dragonite
• ▸ Heavy focus on double battles and Gen 3 VGC-style gameplay
• ▸ References and mechanics inspired by Pokémon Colosseum and XD: Gale of Darkness
• ▸ New battle formats and unique strategic challenges
• ▸ Early playable build; more event content to be added
