Okay, so I got some stuff.
Projectiles are great in the match up, and should be used a lot. >=o
If Jiggly approaches you with Dair or anything that leaves her close to you shield, Usmash OoS.
For recovering, just don't be predictable when you recover. >_>;
And a bomb out can also help. Ibomb when your recovering from a high position.
Jiggz Dacus has a lot of range, but its not that hard to see coming. The only times I got hit with it was when I was trying to SH -> pull out a bomb. So maybe you should keep at a distance when you do that.
Her Fsmash doesn't even kill? o_o;
Its like opposite-kirby.
Use Nair or something to punish pound. Don't try to shield grab it.
Moar coming later maybe.
