Going into The Devourer Below you definitely want to get rid of the Delve Too Deeps. I sometimes feel flashlights are better valve than the Rite of Seeking. It costs two fewer resources, isn't quite as good at -2 shroud compared to the +3, but doesn't have the downside if you pull a nasty chaos token.
Clarity of Mind is also quite slow. You should look to get Peter Sylvestre in there instead. He reliably tanks excess horror while boosting your baseline stats. You can upgrade Fearless as a quicker way to get more uses out of Agnes's ability.
Other than that, Lucky! is a great addition to any deck. It is like an Unexpected Courage that you only have to play when you need it!
It is not bad.
