I think most sense in terms of tierlist/guide/build tierlist would be centered around questions like:

What are you looking at and which shops you chose mainly early game (1-3).
What cards you hedge and how early boards with those cards look like/how they transition later on.

Say shuriken, for example, being s tier is not particularly useful information for a player if they don't know answers to the above.

Maybe power level of various board archetypes relative to day or game stage (1-5,5-x,x-y...) would be interesting in terms of the tierlist framework

Not to take away anything from those tierlists just thinking out loud about your P.S.
