When you have this card in your hand, you have a choice. Either draw a card for zero resources or spend a resource to play Quantum Flux and basically draw a card. I'd rather have the resource and I'd definitely rather have filled this card slot with a card that did something worthwhile. The default cost of drawing through your deck is just a horror. Perhaps you're better off putting a card in that just heals horror, if that is a concern.

It is worth mentioning that there's an encounter card in Dunwich Legacy that this card perfectly counters. I wouldn't fault someone too much for playing Quantum Flux in the Dunwich campaign, but there are ways to counter that encounter card that aren't a waste of a card slot, like Ward of Protection or just finishing the scenario in a timely fashion or resigning when your deck gets low.

This card will also occasionally benefit you by updating the distribution of your deck as you shuffle in your good cards before you happen to draw your weaknesses, but this is offset by the times you have already drawn your weaknesses and Quantum Flux becomes a sub-par skill card.

This is an absolute must have card for pretty much every investigator that can take it.

Not having to worry about running out of cards during The Dunwich Legacy is wonderful (Can't say any more than that to avoid spoilers). Potentially getting good one use cards like Astral Travel/Storm of Spirits/Hypnotic Gaze/Blinding Light back into your hand "quickly" is super-powerful. Combine this with Arcane Initiate & Scrying, and you can fairly quickly get those cards back.

This card is very useful in a few cases:

The first is if you get rewards from searching your deck, like any research power. Mandy, Daisy, Minh, all of them benefit from putting astounding revelations back into their deck. Every time you use quantum flux, you’re giving yourself six resources later in the session. If you’re Luke, this is a great way to keep your gate box powered up by reupping enraptured.

Another is if you have a weakness or weaknesses that get shuffled back into your deck until your deck is very small. Sefina saves herself hit points and horror when she puts quantum flux in her deck.

The final case is anyone in Dunwich, which punishes you by trying to run out your deck.

So one thing the other review aren't trying to tackle is how efficient is this as horror "healing"

Let look at the facts, Quantum flux replaces itself in your hand so it does not cost a card, so its true cost is 1 resources and 1 action (to play the card), given it is only an insight (outside of Joe) I don't think there's anything special you can do with that tag so you are probably always paying full price for this.

Would you use a location that had the effect "1 action, 1 resource>Heal 1 horror" and the answer is "sometimes!", sure its probably not worth doing but "sometimes!" it might be the difference between insanity and being king of the deep ones!. (I'm not sure what this game is about)

So Pro's can be listed to: Recharging a search heavy deck Diluting Weakness Avoiding Punishment for decking out 1 Beautiful point of horror prevented

I think this card is obscenely good in Dunwich and as a one of that just shuts down the main punishment mechanic its efficient at its job but not a card that should be instantly dismissed elsewhere, because a card with art that pretty needs to go into decks.... "sometimes!"

It's an amazing pick for Dunwich Legacy to counter certain nasty treacheries and even final boss. You definitely should pick 2 copies for anyone who can have this card via deckbuilding options. You can even buy Versatile to have it on anyone. Even if it didn't find good usage during scenario, you still can submit it to skill test
