So here's my game state; I have Beyond the Veil in my threat area. One card left in my deck. Deny Existence in my hand (saving it for this exact treachery). I draw a card in upkeep, so Beyond the Veil triggers immediately and I use Deny Existence to prevent the 10 damage. Phew.

Unfortunately, your deck will only cycle when you would draw a card from an empty deck. So at this point, I still have an empty deck.

So what happens in the following mythos phase? I draw another Beyond the Veil, it goes into my threat area and immediately triggers. ...But wait! I have a Ward of Protection. PHEW!

But unfortunately Ward of Protection only cancels the revelation effect, so the "Surge" keyword still applies. Oh well, I can handle the subsequent surge card, I'm sure...

...

Beyond the Veil AGAIN! Are you kidding me?! Instant 10 damage, because at this point my deck is still empty. Never has Arkham Horror kicked me in the balls as hard as this. I took all the mitigation that could be reasonably expected for this card, and still I couldn't survive it. Not a particularly fun card to play around, but it sure is a memorable one.

A thematic weakness but not much of a threat. Looking at the two elements, the effect and the discard condition, we get:

The effect: Luke is removed from his location and moved to the reverse side of Dream-Gate, where he can sit in isolation and think about what he's done. This can curtail 0-3 of Luke's actions, depending when you draw it, since he can still do things like draw cards, take resources, and play assets or events that target himself. It even disengages Luke from his enemies! Once in a very great while, this might stop him from supporting a fellow investigator at a crucial moment, but most times this is very mild.

The discard condition: Either investigate a 6 shroud location to get to the good Dream-Gate or wait until the end of the turn and take 2 horror. In either case, Luke then moves to any revealed location. Since Luke has 9 Sanity, this is almost like a slightly-damaging extra use of the Gate Box, and, in play, this has almost always been a welcome draw.

All in all, this is a way below average signature weakness. The only way it could be less of a weakness is if it just said "add a charge to the Gate Box."

Not much of a weakness, to be honest, although at least it messes with Amanda's mechanics. Looking at the two elements, the effect and the discard condition, we get:

The effect: If this is in Amanda's hand at the beginning of the Investigator Phase, she must put it underneath her, making her a poorer Preston. elkeinkrad's suggestions of how to deal with it are pretty solid -- commit it to a test (yours or someone else's) before the beginning of Amanda's turn or overwrite it with Obscure Studies. You can also just power through, doing testless actions or throwing in more icons than usual. There are a few cards that might let you find and discard this, but usually Amanda would prefer to get rid of her Basic Weakness, since it's likely to be harsher than her signature. Once in a while, this weakness will catch you in a very bad place, but, most scenarios, it will be the lightest of speed bumps.

The discard condition: Discard it at the beginning of Amanda's next turn or overwrite it with her signature.

All in all, this is a way below average signature weakness.

This card is super fun for Dexter, who can remove it from play without paying any of the negative effects. And most Dexter decks are overloaded with assets, so not committing cards during your turn doesn’t seem like a huge problem. At 4XP, it’s expensive, but slotless plus-one to every stat can be useful against diverse encounter decks like Innsmouth.

I'm loving this upgrade on Survival Knife (2), which allows you to fight and deal damage as a during the Enemy Phase BEFORE the enemy can damage you. That attack with this upgrade becomes ( + +2) and deals 3 damage (or more with Vicious Blow or Vicious Blow (2)).

Use your last action to move into a location with an enemy (or one location away from an enemy with Hunter) and deal at least 3 damage to that enemy when it attacks, which may kill it before it gets to damage you.
