I feel like Jigglypuff needs a Fairy-type attack now. Not sure we're I'd put it though.
She doesn't learn many.
Disarming Voice
Dazzling Gleam
Play Rough
And then the non-attacks...
Misty Terrain
Charm
Sweet Kiss
Misty Terrain is out.
Dazzling Gleam? I guess it would be some sort of ranged attack with a ball of rainbowy light or something
. Doesn't seem to fit the character. I wouldn't like it. Jigglypuff doesn't need range!
Play Rough is extremely vague. I'm not sure what they could do with that.
Disarming Voice is probably the BEST fit. Jigglypuff is all about the vocals. I can imagine her going... "Jiggly.... PUUUFFF!" as echoy an attack
.
Charm and Sweet Kiss you'd need to be a bit creative with....
Then comes the question what attacks you replace. Sing is staple. It just needs a buff. Pound is great too... Rest and Rollout are also awesome. So I don't know! Maybe if you use Sing again while Sing is still happening it can shoot a Disarming Voice. A short/medium range ranged attack with a large voicey projectile (that goes out in a cone with the scream). Maybe it is powered up by the duration of Sing. Sing still works the same, it can just turn into a Disarming Voice attack suddenly and hit with a medium ranged attack. I'm imagining the Singing voice suddenly becoming loud and echoy for the attack.
