How to Start Over
Pivoting is a pretty well known concept in The Bazaar, but in some cases, pivoting is more like a full restart. Under more ideal circumstances you're able to take a current build, add a new important piece, and slowly shift closer towards the newer more powerful strategy. This way you have a solid baseline to work with while making the shift.
Unfortunately, there are many times where you aren't given this luxury. Sometimes your build just sucks. When this is the case, your best bet is to search for the strongest item you can find, regardless of whether it fits your active build.
Unless you have a surprisingly good amount of gold and/or a strong Economy (which is unlikely in this scenario), don't settle for something mediocre. You want the most premium item(s) you can find. Ideally you're looking for something Gold/Diamond tier, and you want it to be a pillar of its archetype.
Finding powerful and unique enchanted items is another alternative, though much less defined and far rarer to pull off. A big part of pivoting is having an idea of the items you could be looking to pick up. Random enchanted items from a vendor aren't exactly something you can plan for in most cases, especially not when desperately behind.
At the end of the day, unless your current build is 1-2 items short of becoming really powerful, you're better off looking for something else. Play knowing that you'll be scrapping it as soon as you can, and take as many opportunities as you can to shop for items. Unfortunately this means occasionally skipping some good events, but it's necessary if you want the run to continue.
Atlatl
Atlatl is a powerhouse of a Weapon. While its numbers obviously don't reach as high as some others, its actual DPS often goes unmatched. Very few items can reach a one second Cooldown, meaning almost nothing can rival its speed. This makes it a phenomenal target for enchants as it will get multiple uses before the opponent's items even get their first cast.
Having only one win within the first five days of his run, Kripp eventually found a 
Crook and Atlatl from the same Weapon vendor. While there was almost no synergy with his current build, it allowed for the opportunity to shift into something better.
Now at this point of the game, Crook has an expiry date. Post-nerfs it's far weaker at Diamond, meaning it won't scale up to the same crazy heights it would before. For the time being it's definitely a huge improvement, but Kripp knows he'll need to shift gears in order to survive the dangers that live beyond Day 10.
Weapon skills became his focus, allowing him to acquire 
Right-Handed for a solid flat Damage boost. While this may not look super impactful at this stage of the game, keep in mind that it helps bring Atlatl closer to its one second Cooldown. That can be a huge difference down the road.
Kripp applied a Heavy enchant to his Atlatl. This is an excellent way to disrupt the enemy since the Slow will almost certainly be applied before any item can react. While not mandatory for the build, this is definitely a priority choice between enchants, with only Icy and Turbo rivalling it. Alternatively, Restorative/Shielded/Obsidian could be chosen if you're lacking in defenses or sustain.
Crow's Nest
Crow's Nest is a Vanessa staple, and a very uncommon find for Pyg. Generally the one-Weapon builds that Pyg plays are the slower HP stacking type like 
Double Whammy or the long haul Economy 
Beast of Burden. However, this rare find from Pearl's Dig Site is a spicy pickup alongside Atlatl.
Kripp enchanted the Crow's Nest with Turbo, pairing perfectly with the Heavy Atlatl. While he wasn't at the guaranteed 100% Crit threshold, Crow's Nest made it pretty darn close.
Spices
Spices is a unique but powerful single-Ammo item. It can add a huge amount of Damage alongside a wide Weapon board, though when paired with a single Weapon, it's often even crazier. Since the Damage scaled is based on your weakest's Weapon, depending on the setup this isn't always favorable when playing multiple Weapons. But when you have a single threat, Spices will double it.
While somewhat of a rare find in its own, Kripp found his from the Thug PvE Encounter. Though to be fair, among the rest of the build, Spices is actually a more realistic pickup. After all, it's still a Pyg item.
If you want to take it a step further, adding 
Gunpowder gives a second chance to double up the Damage. Given how fast the build is, this probably isn't needed, but could help in longer fights.
Dooley's Scarf
Dooley's Scarf is a rather interesting utility item. There are very few ways to reliably counter Freeze, but Dooley's Scarf does it incredibly well. While it's certainly not an item you'll typically build around, it fits really well into this setup.
Positioned between the Spices and Atlatl creates an excellent insurance plan, and helps ensure Spices can actually make it through its relatively long eight second Cooldown.
Another rare find from Street Festival event. Kripp's item also had the Shielded enchant on it, but this really didn't matter considering its main purpose was to protect his other items.
