I remember this being discussed a while ago, but don't know the specific thread and don't remember all the result so I'll just bring it up here.
-Are there going to be separate rankings for things like Prizes, Ruins, and Shelters?
I think it'd be fun to rank each of these Types in their own lists.
-Will the $2 category change to $2- to include Poor House?
I believe the consensus on this one was yes, and it seems like the most reasonable way to get poor House in the rankings.
-How will Knights be ranked?
I like the idea of having Knights be ranked as a $5 card with the other $5's, plus a separate list where we rank the Knights against themselves (like the Prizes/etc above)
I think some other stuff was brought up in that thread, like whether to include the basic treasure and victory cards, and there might have been some talk of some way to include Spoils in a list?
Another idea I had that might be fun would be just a straight top-10 list, ignoring cost. How would the community collectively rank Chapel, Masquerade, Ambassador, King's Court, Sea Hag, etc. against each other? A fun side effect would be that this produces a community-chosen most power-filled kingdom that may or may not be interesting to play.
