I wonder why anyone would not take this card in pure standalone decks. Although the card's effects only refer to campaign mechanics it does not prohibit you from taking it, granting you 6(!!!) extra health and sanity. Yes, the stat dump is suboptimal in some decks, but everything is better than dying, right? And since you are only playing a standalone you are not stuck with this crappy investigator for the rest of the campaign.
I guess I have my answer after reading the last part of the card: "for the remainder of the campaign."
So sadly (or luckily, balance-wise?) no abusing it in standalone games. Also, I only just realized that flipping the card is not a replacement effect for being defeated, so also no bonus health/sanity.
Always fun talking to myself...
