- "As If": This was added to the FAQ (v.1.7, March 2020) and then amended (v.1.8, October 2020). You can read the October ruling on the ArkhamDB rules page here. (I'm adding a hyperlink rather than retyping the rules in case in future the ruling is changed or amended - at that point, the rules page will be updated and all ArkhamDB FAQ entries will link to the correct ruling.)

FAQs
(from the official FAQ or responses to the official rules question form)Reviews
Game designer Matt Newman has confirmed on Twitter that The Watcher’s Grasp effect includes causes the Spectral Watcher to exhaust: “Q: Does the Spectral Watcher exhaust after moving and attacking with Watcher's Grasp? If that's the case, it would not attack later in the enemy phase, right? A: Yep!”

Ruling from Alex Werner, FFG Game Rules Specialist via the official rules question form:
Question: Hello! If during Mythos Phase, the treachery Watcher’s Grasp makes the Spectral Watcher “move, engage, and attack as if it were the enemy phase,” can I swing my Survival Knife (2) at him, which has a reaction trigger of “when an enemy attacks you during the enemy phase”?
Answer: No. Survival Knife (2)’s reaction ability can only be triggered during the enemy phase; Watcher’s Grasp does not create an “enemy phase.”
(So with treacheries like this, which cause enemies to attack "as if" it's the enemy phase, other cards will not "resolve with the altered game state in mind," in contradiction of the FAQ rules on "As If..." This raises the question of whether MJ's ruling about the enemy exhausting would also be invalidated.)
