UPDATE: Upon further play, these replacement/alternate signatures are not really all that much better than the original ones.
The problem, especially at low player counts, is that most scenarios rarely have you walking around with spare clues. Typically you're spending down to 0 clues to advance the Act Deck, so the accompanying weakness is a dead draw AND gets shuffled back into your deck. Again, and again. And suffer a horror each time.
There are upsides though! This generates a clue out of thin air, which can sometimes let you ignore a challenging location.
And it’s fast, so it doesn’t trigger an Attack of Opportunity. Which allows you to hold onto this card until you get attacked at a location without clues, then play it to earn a clue (with Roland’s innate investigator power) when you defeat the enemy.
