This card, as well as its guardian high-level counterpart, is actually not that good

What is the goal of a main fighter? On the first round, prepare to fight enemies that will spawn in the upcoming Mythos phase. For that, you need to find and play a weapon. To increase the chances of having a weapon in the opening hand, fighters dedicate several weapon "slots", usually around 6. Prepared for the Worst can be used in one of the "slots", as it has a high probability of resolving into an actual weapon

This card just does not work in this setup because of that 6-resource cost. Let's consider different scenarios:

1. You drew the Thompson in the opening hand. Great, but you have to spend an entire action just taking an extra resource to play the card. You have one action left and no money. But at least you are ready to fight!
2. You drew Prepared for the Worst in the opening hand. Okay, you play and find Thompson... but you have 2 actions left and you are 2 resources short! You have no choice but to sit empty handed
3. If you use, say, Backpack to find your gun, it's even worse

So, if you want to play a gun in the first round, you'll have to find another one of your guns. At that point, it's better to ditch the Thompson altogether. If only it cost the same amount of resources as you started with... unfortunately, there's no another 0-level big gun. Took Thompson myself and regretted it, now I plan to upgrade into M1918 BAR ASAP

I have a question about the treachery card Glimpse of the Underworld.If an investigator draw Glimpse of the Underworld and it be put into play in his threat area, then he decide to trigger its ability to discard GotU and take 1 damage and 1 horror, would he take 1 additional damage or horror? If another investigator help him resolve GotU by triggering the ability, would that investigator only take 1 damage and 1 horror?

Would you like to reduce the difficulty of attacking a Mindless Dancer by 2 and eliminate it in a single action? I thought so!

Have you let things get out of hand in Hemlock, and are staring down the barrel of a Crystal Parasite or accidentally chonky Poisonblossom?

Perhaps that Conglomeration of Spheres would better spend their days as a collection of dissociated orbs?

Perhaps you've taken Nasht's words to heart, and you know what the true weapon is in the Dreamlands.

Or maybe there's just some other high health nasty you'd like done with in one go, like a Corpse Dweller, Deep One Bull, Apex Strangleweed or Oozewraith.

The card is expensive, as it should be.

You have to take and pass a test, as you should do.

You probably need to be a mystic, but you're murdering monsters with your voice, not a gun (or maybe a 5xp card.)

You could even wear Fine Clothes, but why dress smartly when you can just bellow at fools in your dressing gown?

The card is level 0 and is excellent across so many campaigns. If you can slot a one-of copy, why not?

Now excuse me as I pack two copies for Before the Black Throne.

Strange, often completely benign weakness, that unfortunately incentivizes you to stack all of the keys on a single investigator. Rules notes:

• The first option has been ruled to flip the key back to its Stable side
• You cannot choose the first option for a key that you already shifted

Wilson is generally very strong, but he's got extremely high synergies with George Barnaby, since:

• George wants to discard a card every phase, and this lets you discard during player windows you might not otherwise be able to easily discard in, such as the Enemy Phase, or the Mythos Phase if someone ends up taking a skill test.
• Obviously any card with or icons can be discarded to Wilson and will then boost your next skill test that round, but if it's the first card you've discarded this phase, you can commit it again to the actual skill test. So something like Inquiring Mind (assuming there's a clue at your location) can suddenly become an effective +6, and draw you a card.
• Cornered is an obvious comparison; it lets you discard a card for +2 regardless of icons (turning Inquiring Mind into an effective +5), but it has some subtle differences. Wilson potentially lets you get a higher benefit (if the card has more icons), gives you some flexibility (you can gain resources, draw cards, and heal Wilson too), and lets you discard a card in an earlier phase to bank the boost for the next skill test later that round. But I mean, they're not competing, you can run both. If Wilson was nothing more than a third copy of Cornered, it'd be a great card in almost every George deck.
• And while Last Chance is already great for George, Wilson makes it nuts. You can potentially do something like: In the Mythos Phase when your teammate takes a test, discard Last Chance to draw a card, then resolve any 6 effects off Wilson. Then later when you commit it from under George, you get another big boost to the test depending on cards in hand (which you can boost further by discarding more cards via Cornered or, if Wilson had readied by now, Wilson again, collecting whatever rewards that gives plus drawing another card), then when you almost inevitably pass, you draw another two cards.
• George works really well with Dark Horse, but one challenge of a Dark Horse deck is occasionally needing an influx of resources to help with setup or to pay for a large asset. Wilson turns and icons into resources at a 1:1 ratio which means you can turn something as boring as an Unexpected Courage into a mini-resource cache, draw a card, then still commit it later to a test, without using a single action, which can occasionally be very convenient.

Dauntless Spirit is worth calling out as well. I'm not quite sure if it would work with George ("You may commit facedown cards beneath George Barnaby to skill tests as if they were in your hand.") or would not (since they don't work with Amanda Sharpe). If they do work, then Dauntless Spirit is pretty decent, as it reads something like "get +3 to your next skill test this round, and heal all damage and horror off Wilson", although as weird as it is to say, that effect might not be quite strong enough to be worth 1XP in most George decks? Pity that Survey the Area isn't in George's card pool (assuming the cycle works with his ability at all).
