>>57158238>Would metal sound remain a steel type move is it going to be a sound type move? There's plenty of moves like that. Between Ice Punch, Fire Punch, Thunder Punch, Mega Punch, Comet Punch, Dizzy Punch, Shadow Punch, Bullet Punch, Jet Punch, and Mach Punch, only one of them is actually Fighting type. Pollen Puff is Bug type and not Grass type, Floral Healing is Fairy type and not Grass type, Steamroller (Hard Roller in Japanese) is Bug instead of Ground or Steel, Silver Wind is Bug type instead of Flying type, etc.
>Also soundproof is going to be the levitate for that typeIt wouldn't be the only type with an ability that grants an immunity. Water Absorb, Volt Absorb, Lightning Rod, Dry Skin, Storm Drain, Flash Fire, Sap Sipper, Earth Eater...
I'm more concerned about how they'll handle the distinction between Sound moves and Sound-based moves that hit through substitute. Maybe let Psychic in on the fun and have it be "wave" based moves -- soundwaves and ESP waves -- that can hit through substitute? Or maybe have it be the secondary effect on Sound type moves, like how Fire type moves have a Burn chance or Ice type moves have a Freeze chance.
