@LibraryAdventurer:
I think your suggested Iron-Processor is a bit too strong for $3, and would be good at $4.
-If you have a victory card in hand, you can use it as Smithy with a minor drawback (but with other options)
-If you have copper in hand, you can use it as (approx.) +2 cards +$1, which has similar strength to smithy
-If neither of the above apply, you have a very strong hand (or a lot of curses), and neither of the options is really bad (but also not that good)
(and it combo's with dual typed cards)
On the other hand, your Diplomat-Smithy suggestion is very very weak. It is strictly weaker than Moat without reaction. The removal of politics is good (and it doesn't matter that much that the player on your left chooses, Jester and Possession are worse than this w.r.t. the importance of seating order)
For Diplomat-Smithy I would suggest the original card at $3 with removed (reduced) politics:
Diplomat-Smithy (Action, Cost:3)
+3 Cards
The player to your left may draw a card. If he does, all other players do as well (including you).
I think this wouldn't be too strong.
If there is no discarding attack on the board, the player to your left will usually want to draw a card (especially if the current player has no actions left), because drawing a card out of turn (if you can keep all your cards until the start of your own turn) is usually stronger than drawing a card mid-turn. In this case this might be almost Council Room for $3, but that's not as good as it sounds:
-Council Room generally is pretty bad without discarding attacks;
-The +Buy is really strong on a terminal card which draws 4 cards.
On the other hand, if there are discarding attacks (and you have a few), the player to your left will usually not draw the card, and then this becomes Smithy for $3. Yeah, that's strong, so it definitely combo's with discarding attacks. But if you compare with Council Room or Governor which also combo heavily with discard attacks, then it doesn't seem too strong. Council Rooms draw 1 card more and Governors are non-terminal, and while they give the opponent the benefit of choosing their 3 cards from a bigger hand and both cost $5, they are enough stronger to justify this at $3, in my opinion.
PS: @manthos: I like most of the cards you suggested. They are all pretty balanced (or could be balanced with a minor change), and they all have some reasonably new idea to them. I didn't comment on any other card, because I agree with what (at least) one other person has said before on them, and I don't want to repeat other's opinions.
