Fast. Play when an encounter card or an enemy attack would cause you to do one of the following (choose one): Discard cards from hand, lose resources, lose actions, take damage, or take horror.

You ignore that aspect of the effect. (Each other aspect resolves normally.)

FAQs (taken from the official FAQ or FFG's responses to the official rules question form)
  • Q: For cards like Deny Existence, "I've had worse…", Delay the Inevitable, etc, do they directly or indirectly work against effects that do not deal damage and horror directly to your investigator (e.g. Snake Bite) or deal direct damage to other things as well as your investigator (e.g. Centuries of Secrets, Ceremony Room)? A: Delay the Inevitable, I've Had Worse and Deny Existence only work when you (aka your investigator) are being dealt damage/horror. If damage or horror is being dealt directly to a card other than your investigator, you cannot use Deny Existence, Delay the Inevitable, or I've Had Worse to cancel/ignore it.

Ward of Protection is often considered one of the strongest events in the game, since cancelling a critical treachery can be game changing. Deny Existence is a similar card, that has narrower coverage, but does a better job for what it covers. Compared to Ward of Protection, this card cost 1 resource and 1 horror less to play, and more importantly, it can be played after you failed a test on a treachery.

Imagine you are Agnes Baker and has 3 sanity remaining. You draw Rotting Remains. Normally you would be happy since you can usually pass the test with ease, but since an auto-fail draw outright defeats you, you may consider using Ward of Protection to cancel it. However, if you have Deny Existence in your hand, you may instead take the chance. Most of the time you will pass the test, and if you auto-failed you just play the card to ignore it. In this aspect, Deny Existence to Ward of Protection is like what Lucky! is to Unexpected Courage, that it has an effect even if you do not play it. But the cost is also favorable to Deny Existence. This shows how insanely powerful is the card.

Additionally, Deny Existence can cancel certain weaknesses, since treachery weaknesses are considered encounter cards. Notably it ignores Amnesia and Paranoia in their entirety. This is another really strong ability. Interesting side note: The card can ignore the direct horror from To Fight the Black Wind, and potentially preventing the doom as well.

Being able to ignore enemy attacks is the icing on the cake. Most enemies deal both damage and horror though, so Deny Existence usually only ignore part of the attack.

Not to mention the spell synergy (Arcane Initiate), ignore synergy (Diana Stanley) and event synergy (Sefina Rousseau) the card provides.

Deny Existence is such an excellent card, that it is hard to imagine not putting it in every deck that can take it.

The only failing this card has compared to ward is that it cannot stop cards such as Ancient Evils; you can still lose the scenario with this in hand. That being said, I agree that this is a very strong card. — SGPrometheus · 589
I expect this to be errata'd to non-weaknes treachery pretty soon — Adny · 1
Would this prevent becoming poisoned from [Pit Viper](/card/04078) if you choose "ignore damage"? — panchar · 1
Also, I guess card hyperlinks don't work in comment replies? — panchar · 1
It would. If all damage is prevented than damage was not dealt. It actually that verbatim in the rule reference under Dealing Damage/Horror that if an attack's damage/horror is assigned as a result of an attack then damage/horror has not been successfully dealt — Donel · 13
that if no damage/horror is assigned* — Donel · 13
Additionally, It was confirmed that this DOES work with weakness cards as they are considered encounter cards. Even better, Matt ruled that this DOES ignore Diana's weakness, as her weakness specifies "Cancel" and this "Ignores". — RobSan770 · 2
If I read it right, this card can nullify the whole 10 damage from Beyond the Veil. — Killbray · 72
Does anyone know if this could ignore horror from Dark Memory? I ask because it is an event, which is a player card type, so I don't think it counts as an encounter card, but I'm not sure. — Zinjanthropus · 176

This card is best with Diana, for whom (as long as you have an open spot beneath her) it replaces itself and gives +1 resource (same net bonus as Emergency Cache). It might be usable in some other decks, especially if you are trying to increase your spell count (for Arcane Initiate, etc). Awesome artwork, too!

When using it with Diana, does this card stop Rites of Seeking from ending your turn? My gut feeling is no. It counters the "lose actions" part but the end turn line is an additional effect. Came up in a game last night but I think it'd still cause her to end her turn, she'd just do it with all her actions. — skanedog · 53
@skanedog Rite of Seeking is neither an encounter card nor an enemy attack, so Deny Existence doesn't even trigger. — TheNameWasTaken · 3
