Some thoughts I had...
New Masquerade - Action/Attack - still $3? (but now the name doesn't work as well...)
+2 Cards
You may trash a card from your hand. If you do, each opponent with at least 4 cards in hand passes you a card. You may trash any of the received cards; gain the rest.
(Avoids the pin, and protects against Possession nastiness.)

New Ambassador - Action/Attack - probably more now?
Gain a Curse in hand. Set aside any number of cards from your hand. Each other player, in turn, takes one of the set aside cards, putting it in his hand. Trash any remaining set aside cards.
(This is perhaps political in the sense that you can choose to only hurt one player, and hit with a Curse; but you hurt your own opportunities in order to do so. The trashing is again to mitigate vs. Possession, although you can still lose 1 good card per opponent.)
