This is AIDS. Don't use this. Alright, so this is a variant of Pangoro that , in design, converts various Pangoro switch-ins/lures into set-up bait for sweepers that one chooses to partner with it. The EV spread enables Pangoro to, with 220 Speed EVs (with a neutral nature) outspeed 0 Speed base 85s, such as Cresselia and Gligar - if necessary for the set's functionality. When facing these 'mons in a 1v1, Pangoro has an option to Taunt these Pokemon, so that their utility options do not hinder the sweeper that is to come in afterward. In addition, Mold Breaker enables it to Taunt Aromatisse on a switch-in, as the effects of Aroma Veil are negated. Aside from that, considering the fact that this is more of a support spin on the 'mon, it is best to invest full bulk, and put the remaining 36 EVs in Attack, along with an Adamant nature. (By running 148 EVs in Speed with a Jolly nature, you reach the same speed tier with 11 less attack points.)
The overall idea behind how this set is suppose to play is that when a Pangoro's offensive presence lures in a 'mon like Gligar, Hitmontop, or even Cresselia (in the late-game if the item is already Knocked Off) - Pangoro is able to use Infestation to trap these defensive answers - and either turn them into set-up fodder (Fletchinder works best with this set, as it resists the STABs, and sometimes entire sets of many Pokemon that would be 'trapped'), or pick them off with members of your team that obliterate the given Pokemon.
Low Sweep is the Fighting STAB of choice because sometimes, your opposition's speed upon switch-in is what may hinder your partner'd sweepers ability or inability to penetrate a team's structure. By taking STAB damage and a -1 in Speed, faster Taunters like Cobalion, Drapion, Gligar, Skuntank, etc. won't get the best of you in the match-up.
Leftovers is the item of choice simply because it is the only befitting item in preserving its bulk.
