Initially, this card seems like a more complicated stick to the plan. But a friend and I checked this card for the Vale finale; the possibilities were evident. First, it makes your deck more consistent. Three cards that you know are going to be there, without having to Mulligan for them. For expensive things like Ace in the Hole, or vital combo pieces like Dirty Fighting, that’s extremely useful. Pilfer(3) and Vamp(3) are high XP cards you’ll want to see ASAP. You could place things like Warning Shot, Quick Getaway, or Swift Reload(2), to fit a variety of enemy management plans. Second, you can trigger search effects at will. Trish can use this to grab plenty of astonishing revelations. It doesn’t matter if the search actually locates a card! The third, and maybe the most important, is getting multiple copies of your favorite myriad tricks. Easy Mark and Beguile are my favorites there.

Clarification: 'Engaging Enemies vs Being Engaged by Enemies: When an investigator engages an enemy, that enemy has also engaged that investigator, and vice-versa. There is no difference between engaging an enemy and being engaged by an enemy. Effects that trigger “after an enemy engages you” will trigger at the same time as effects that trigger “after you engage an enemy.”' - FAQ v.1.3, May 2018:

This seems to be mis-labelled, my physical card has this as an Asset, rather than an Event. Given it's a permanent that lets you draw cards to attach to Bewitching before your opening hand, Asset makes more sense, right?

Seems kinda weird. How do I find a card in my top 9 that matches an attached card when the attached cards are face down? I know it's a bit pedantic, but I guess they wanted the draw to be random, but the search to have to find an attached card. Fine, but you'd have to know what's attached, which you cannot.
