Scribe’s Seal
$4
Treasure
Produces $2
While this is in play, when you gain an Action card, you may put that card onto your deck.
Royal Seal’s effect is useful, but at $5 it faces too much competition. You’d rather get that key $5 than get Royal Seal and hope its effect lets you topdeck that key $5 later. I envisioned a replacement for Royal Seal that costs $4, but hopefully isn’t going to be an auto-buy (or have the pile empty too often). Another consideration in making Silver with a benefit for $4 is to avoid powering up treasure heavy strategies too much, which, like Patron, this should accomplish.
I know that Donald X. hasn't even revised Seaside yet, but I can dream that we'll someday get revised versions of Seaside and Prosperity as well. Base 2e and Intrigue 2e are some of my favorite Dominion sets. If only Harbinger had cost $2!
