Yes, his counters are limited, but in a set full of proliferate and with some small blink effects, he could do some work
My personal favorite is still the Mystical Archive because it felt good in Limited formats (mainly being answers, not threats, but still interesting) and some spicy old cards like Channel included
This eight-cost character quests for four lore, which is already a huge amount, but anytime it does quest, you get to ready all the cards in your inkwell
The City's Blessing is trivially easy to achieve, especially on cards that generate tokens, and this one's even better if you combine it with other detective creatures
Readying a chosen character normally comes with the caveat that it can't quest again that turn
Flavorfully, it sort of represents a feeling of creeping dread that gradually becomes abject fear
