OverviewWriggle's a bit of an unseen gem. Her Attack and defense stats is just 10 shy of Momiji, but makes up for it with evened out defenses and a slightly higher Speed and HP. These little tweaks make her a great HJK user. A major Hinderance to Wriggle's destructive power is Her small number of physical attacks and lack of Leaf Blade, which would be a great STAB move for her. She also has access to Tailwind, which is also a good thing.

The good thing about Wriggle is that despite her tiny movepool, she can run sets similar to Momiji while setting herself apart in battle. Tailwind in tandem with High jump kick is a great way to take things out effectively before they do damage. Needle Arm or Power whip are also nice if a dark type comes in to ruin your fun. Soar is also great STAB to hold on to.
Other OptionsWriggles options are kinda limited, but very effective. She carries Return, an oft-not-seen attack, which carries slightly less power then HJK at max happiness, but doesn't carry the risk of Recoil damage if it misses, and the ever reliable Poison Jab.
Checks and CountersWriggle hes been cursed with the dreaded Nature type, meaning that most common attacking types(sans Beast and Water) are proplably going to OHKO it. ARemi is a good case of this, as it resists HJK and can force Wriggle to swap out. In general Wriggle's somewhat frail, so hitting hard enough can work too.
