This card is fantastic and stands alongside Drawing Thin as one of the survivor cards of which other classes are actually jealous. I hope it doesn't similarly end up on the chained list of taboos.
Android Netrunner had Archived Memories for a similar cost and effect, except in that game the archives was a vulnerability rather than a potential resource farm. Still the card saw a lot of play.
The rules reference p5 cites a level 0 card as being one without any pips under its cost, but the FAQ errata for the core set investigator fixed cards makes it clear that you can't use this to return Nautical Prowess. So what can you do with it?
Well, Resourceful is an universally played card in survivor, but only returns cards. This is a proactive version of the same effect and happily returns cards from other factions. It is therefore especially excellent for characters who simply splash survivor, such as the Dunwich investigators. Being limited to level 0 cards is fine when it includes every card in your starting deck!
This card gives the ability to better spam something important like Ward of Protection or "I've got a plan!", recover a defeated ally or spent item, and turns treacheries that mill your deck into greater card selection.
Cross your fingers and pray for a 5 xp upgrade to this that returns any card. Or a Yawgmoth's Will, I'm not fussy...
