FWIW, try to value them by how much you'll actually use them. Sure, the regular sets come with many more cards, but it wouldn't be saying much if you didn't like say, half of them.
As far as the rest of them go, Summons isn't too shabby, nor Dismantle.
You lost all credibility to me when you rated Governor and Stash as 5/5, but Black Market only 3/5.
Based on the pattern, I assume Prince would get a rating of 8/5?
It would get a 3.6/5. Not great, but not terrible.
My point was that Governor (ranked 5/5) and Stash (also ranked 5/5) both have in-game costs of
, and that Black Market (ranked 3/5) has an in-game cost of
. Going back to the original post, Walled Village and Envoy both ranked 4/5, and also both have an in-game cost of
. So Prince, logically, has to get a rating of 8/5 given its
cost.
