Here are just my 2 cents:
39. Sea Hag
Pretty low, you think. Well, it's one of the more ignorable cursers, I find. It does nothing for you. And trash one cad at a time would neutralize it
This strikes me like saying moat neutralizes witch.
34. Soothsayer
A curse-giver which gains gold. This card gives great longevity, but... well, gaining gold is a 5ish value, giving a curse is a 4ish value, labbing opponent a 5 value to them...
For them it's a lab, for me it's a 5ish plus familiar.
Aside from these nuggets of criticism: I really, really enjoyed reading your list, thanks!
I do also agree in many ways, where you are opposing mainstream opinions:
- Counterfeit, Junk Dealer and Upgrade in Top20? Yeah!
- Haven in the bottom thirty? Great! It is often just a cantrip which turns a card into a duration card, which is a big detriment.
- Scheme does so, too - good idea to put it in the second half.
- Rats merit this low position: they are useless without TfB, and even with it, they are often just a trap, as matching with TfB does not happen automatically.
