"Fool me once..." is an alright card if played fairly, for it purpose of cancelling a future encounter card - it comes cheaper than Ward of Protection (since you don't have to pay a horror), but costs an extra XP and has more stringent restrictions on when it can cancel a card. Other reviews give more in-depth descriptions of this.

However, there's an important (perhaps unintended) usage of this card: unlike most treachery-interaction cards, this one doesn't specify that it only applies to non-weakness treacheries, so you can use it to trap a weakness to avoid redrawing it when you reshuffle your deck.

Most Guardians don't really have the draw to take advantage of this, but this effect can be especially strong in Joe Diamond, who does have access to the tools needed to repeatedly draw his deck, and this can let you really easily facilitate infinite combos, even if you draw a particularly nasty weakness (such as Amnesia).

This card is actively bonkers for Daisy Walker, who can frequently draw through her entire deck to find it using Old Book of Lore and other search/draw. It costs 1 XP Total, thanks to Myriad rules, and gives you tons of free actions for resources provided you are meeting the requirements. Actions and autosucceeds are way more important than resources. And in a pinch, it pitches as a wildcard!

If you expire Pendant of the Queen when your deck is near empty or empty, you can stack your deck with three Segments and immediately draw into and play them again. Combined with secret charging abilities like Astounding Revelation and Enraptured, this card can make five-action life a reality for seekers.

When it says “if no such token is revealed, choose one of those tokens and ignore the rest”, does it mean “one of the skull, cultist, tombstone, elder thing, auto fail” or does it mean “one of the 5 revealed” tokens?

I was chatting with someone online who mentioned that they took two copies of this card. That seems wild to me. If you want testless clues as Stella, there's the raven. A copy of charisma is all you need there. You can even recur it with resourceful. But two?

Because a lot of the time, your first action is going to involve you and the enemy you got during the mythos phase. You’re going to want to punch this person, hit them with a fire ax, or a chainsaw, or dodge them so you can go on with whatever else you were doing. Especially if they're alert.

If you want to modulate difficulty with Stella, and that’s perfectly reasonable, drawing thin costs an action but one less XP, and you can use it whenever you want. Flub a track shoes test. Mess up an attack so you can play oops (Which is particularly funny with the chainsaw). Get paid or draw!

One copy is amazing though, because suddenly you are using your old ring of keys to get free clues at three shrouds, automatically hitting rats... getting one failure that leads to two successes. Definitely an early pick with Miss Clark that helps every other card she might want to play.

Now that our pal Stella is around, along with Granny Orne, failing by one becomes even better. If you have the Ankh, or even better, someone else on your team is wearing it so you can keep your rabbits foot, once return you can succeed automatically. Not just some of the time, not just if nobody draws the tentacles, but automatically with an Orne/Ankh combo.

But it’s probably not worth doing an entire side mission for that. So now consider other things you can do when you fail by just a little: use oops, which lets you auto hit, even better if you are using your chainsaw. In that case, deal three damage and get another supply on the chainsaw, or deal four damage. Or use live and learn for a similar effect, resolving a failure for the supply then immediately attacking again without taking another action.

Maybe you’re holding down the fort on clues, you can use look what I found! with your Ankh, to get two clues for two bucks. And if you’re drawing thin, you can make sure you fail the test the first time, get paid for it or draw cards, then pass. Booyah.
