FHV-Era Winifred Update/Retrospective:
When the investigator decks came out, I saw a lot of buzz for Winifred, but it died down almost immediately when Edge of the Earth released with a pile of interesting new investigators and a very powerful card set that offered Wini almost nothing she wanted. Edge of the Earth. EoTE was an asset-heavy set chock full of multiclass synergies, bonus action sources (Eon Chart, The Red Clock, etc.), big money tech, and trait-based boosters (Crafty) that rewarded playing items and assets instead of skills. So did the best rogue card in the set (Black Market). Apart from offering Savant and Blur to let Wini pass will tests and waste less time evading, it offered very little support to skill-based, gun-based, foot-based, or oversuccess-based green archetypes. It was the meta of building a big board and then taking lots of tests at high static numbers.
Fortunately, The Scarlet Keys and Hemlock Vale have been much kinder to Wini, delivering plenty of support in all the areas she needed.
Deck Manipulation & Consistency:
Underworld Market is an amazing boon to Winifred, especially for long scenarios. By sticking her weapons and tools in a side deck she can achieve a much higher density of skill cards in her main deck, allowing her self-replenishing skill card engine to run much more smoothly than before. If you end up cycling your deck the option to leave spare weapons and backup soak options in the market until needed unclogs your reshuffles beautifully. Being able to hide your key assets elsewhere also makes level 0 Daredevil feel a lot more reasonable to use.
I'm not sure whether Friends in Low Places is useful or overkill and whether you use it to tutor for assets or refill on skills, but I think you definitely run it. "Bolstering" seems like kind of a trap; I think you only need prompt, want versatile, and maybe stretch to experienced. Innate and Practiced are the obvious choices for vacuuming up skills, but there are a few skills with gambit, fortune, trick, and cursed which can help you double-dip into other card types if you wish.
New Foot Payoffs
British Bull Dog and Thieves' Kit came in as simple reliable foot-based combat and investigation options, each with lots of support cards available, making it much faster for a low level Wini to get rolling. Disguise, Lightfooted, and Dirty Fighting massively increased the reward for taking normal evades, too.
Oversuccess Support
Grift and "I'll take that!" each in their way give a resource per point of success up to some cap, and Grift also gives you a diff 0 test to style on with other effects. Breaking and Entering joined the roster of reusable oversucceed events and Chuck Fergus level 2 appear to make trick builds easier to scale up.
Slot Support
Hidden Pocket can go in the market, and open up the chance for Wini to combine the Beretta M1918 with an investigation tool or Eye of the Djinn, or run Lockpicks, Thieves' Kit, and .25 Automatic all at once. Or to combine her obligatory Lucky Cigarette Case with more fun toys like the clock or garotte wire.
Considering that recent campaigns have also introduced more reasons to evade and a fair number of scenario-based foot checks, I think it's a great time to dust off Wini and put her through her paces.
