Bite is lulzy in this MU. You shouldn't have to shield, you can just dair all days and there's little our little Jiggs can do about it. You don't really need uair for damage racking, you can save it until 90-100% to get an easy kill (it's remarkably easy to land). Stick to the air, being grounded serves no real purpose. Keep it safe at low percentages, Jiggs can gimp quite well and bair/strong nair/fair are all decent setups at lower percentages, losing their efficiency once they do too much knockback to be followed up.
You won't die anytime soon, probably because of a strong fair at 150-190% (from 190% on, I believe bair kills, perhaps earlier? Someone who knows correct me if I'm wrong). This matchup is really easy once you get the hang of it (playing safe at low percentages, it's really crucial), it's probably something like 70-30 our favor, something that could be considered awful for Jiggs.
Anyway, very safe damage racking, enough (low percent) kill opportunities with uair/fart/fsmash/the basic stuff, all Jiggs has on us is a few unguaranteed gimps.
