Having finished a 2-player run of RttFA with a Chainsaw Yorick deck in the combat specialist role, I have some opinions about this card. I had visions of getting to regain chainsaw supplies while still doing damage and reveling in Survivor BS. The level-0 version was a disappointment for all the reasons listed in that card's page -- it's a bit pricey for most survivor decks and you have to have a copy in hand, 2+ opponents at your location, and 2 resources available, and have failed by 2 or less for the thing to land. Now, RttFA hands out enemies like candy in most scenarios, so this was a likely setting, but it never really seemed like the right time. The card does have icons, and it mostly got used for them.
The upgraded version, which only requires one enemy, has a 3 or less failure threshold, and, importantly, protects fellow investigators from your clumsiness, looks like a better bet, but, at the end of the day, I only used it twice in the campaign (although the use in the final scenario was very clutch), so it wasn't really worth the 4XP to replace both. Maybe a one-of?
