While we are waiting on Renaissance it might be fun to come up with some cards that could match the expansion.
$4
Action
Trash a card from your hand. Take a number of Action tokens equal to its cost in Coins.Nothing fancy, salvage for Action tokens. Could be too crazy.
$4
Action
+1 Card
+2 Actions
Pay any number of Coin tokens, then draw that many cards.A village that converts Coin tokens into Card tokens and liquidates them.
$2
Event
You may do this more than once: convert 3 Coin tokens into 2 Victory tokens or vice versa.OK, doesn't strictly match the expansion as it doesn't seem to include Events and Victory tokens.
This could be bonkers with Baker or even Plaza but at least early in the game you normally prefer 1 Coin token over 1 Victory token. So perhaps it is most interesting in Kingdoms with Victory tokens.
$5*
Artifact - Victory
At the start of each of your turns: You may trash a card from your hand. If you did not, +1 Card.
----------
When you buy this, you may overpay for it. If you did not overpay as much as there are Coin tokens on this, return it to the Supply. If you did, remove the Coin tokens on this and for each you overpaid, put a Coin token on this.
This costs 5 plus the number of Coin tokens on it.The basic idea is that there is only one copy of each Artifact, that it is out-of-deck and that you can bid for it (
not particularly creative as I have something similar in my fan cards set with Conjuration). If somebody bids more than you later though you lose it entirely.
I first wanted to do this as pure Victory card but realized that it is too similar to Mountain Pass and not dynamic enough; in most games somebody will pay a lot of for a lot of VPs late in the game lest somebody pays more. With this you have an incentive to go for it early, even if somebody takes it away from you a few turns later.
The wording is bad though as it only refers to buy and not gain as it should (unless you specify that Artifacts are something like Events, i.e. you can only buy them and then get the card-shaped thing in front of you).
