Updated versions, if anyone feel like commenting.
The issue here is I want a card that (1) can trash money, (2) is a reasonable defense to give you money, (3) but can be strong.
If you have a viking: you can trash a copper, get +3 and then if you draw another copper, you have 4 to spend (and you have trashed a 'useless' copper.) If you have *another* viking in your hand, you can get to $6 pretty fast. Is it too powerful? Maybe a bit coin-flippy?
Viking:
$2
Action-Reaction
Show your hand. Trash 1 treasure. Discard all other treasures. When in this turn you have revealed at least one treasure: +$3 and +1 Card
-----
When you discard this other than during a clean-up phase, you may reveal it. If you do, gain a silver, putting it on top of your deck.
The previous version was a bit too weak. Here you can change an estate for a pawn (or hamlet) and immediately use it. Or even exchange a curse for a copper and immediately use it. Doesn't sound like too bad of a deal. It can distribute curses on buy. (If you have 8 to spend, you can give out 3 curses at once, even.) Has a nice synergie with bridge/bridgetroll/and other cost reduction cards.
Houdini:
$2+
Action
+1 Action
Return a card from your hand to the supply. Gain a differently named card with the same cost. If it costs 2 or less, put it in your hand.
--------
When you buy this, you may overpay for it. For every $2 you overpaid, each other player gains a curse.
Slightly complicated card, but interesting (I hope). If you have useless cards (and especially if there is little trashing), you can 'store' them here. Can also be used for defense. And it gives you VP's. Not overpowered, but also not the weakest card per se, I think.
Dinner Table
$5
Action - Victory - Attack - Reaction
+1 Card
+1 Action
Choose one:
Set aside cards up to the amount of players in the game on your Dinner Table Mat. Return all cards at the end of the game to your deck. 1 VP/Card on your Dinner Table Mat.
Or
Every other player puts one card that you choose from his Dinner Table mat into his discard pile.
------------------------
If attacked, you may discard a card from your hand or your Dinner Table Mat. If you do, you are unaffected by that attack.
Intereting exchange with both others and yourself. You can use it early to gain a gold and an estate. Is it worth it?
I am contemplating of adding a +1 Action to Pediatrician, so it's not a complete dud the turn you use it. If someone else buys a nobles, you might not want to remove Pediatrician from your Tavern mat (or do you? because you can get a gold if you do...).
If someone buys a Colony/Province, you can hurt his next hand, and give yourself a good a (probably) better hand next turn. Sounds decent enough, no?
Pediatrician
$3
Action - Attack - Reserve
+$2
Put this on your Tavern mat.
-----
When a player (including you) gains a victory card, you may remove this from your Tavern mat. If you do, he moves the card to the top of his deck and you gain a gold. If it’s a province or colony: put the gold on top of your deck.
Has already been tested and approved. Not the most inspiring trasher, but it gets the job done.
Smooth Salesman:
$4
Treasure
$1
You may trash a card.
If you do: +$1.
What do you think of the reaction? Interesting synergie with (for example) Oasis, but also is an interesting response to Goons/Militia/Torturer kind of attacks. Greek Goddess usually won't come into play until later in the game, and even if you don't use the reaction: the big expensive peddler and the VP's look like it's worth picking up at price 7, no?
Greek Goddess
$7
Action - Victory - Reaction
+1 Card
+1 Action
+$2
---------------
When you need to discard cards other than during the clean-up phase, you may reveal this and trash any number of those cards instead.
--------------
3 VP
