After having neglected Dominion for nearly 18 months to play MtG, I've decided to brush up on my skills, and work on my fan set, which still hasn't been completed. These are the cards so far:
Abandoned Village
Action-Reaction: $4
+1 Card
+2 Actions
--------------------
When a player gains a victory card, you may
set this aside from your hand. If you do, gain
a Silver, putting it into your hand. Return this
to your hand at the start of your next turn.
Bath House
Action: $4
+1 Action
+1 Buy
+$1
Trash 1 or 3 cards from your hand
Archer
Action: $4
+1 Buy
+$1
You may discard a card. If you do, +2 cards.
(A suggestion made by LibraryAdventurer. The old version feels farily similar, but I've liked playing with this version as well.)
Missionary
Action-Reaction: $2
Trash 2 cards from your hand.
-------------------
When you would gain a card, you may discard
this from your hand. If you do, instead gain a
card costing exactly $1 more.
Scribe
Action: $2
+1 Card
+1 Action
Name a card. While this is in
play, when you gain the named card, put it on
top of your deck.
Panacea
Action: $3p
+1 Card
+1 Action
Choose one: +1 Card; or +$1, +1 Buy; or trash
a card from your hand.
Assassin
Action-Attack: $5
+$2
You may put your deck into your discard pile.
Each other player gains a curse.
Tailor
Action: $2
+2 Cards
When you gain or play this, you may put a card
from your discard pile on the bottom of your deck.
Prospector
Action: $5
Trash a card from your hand. Choose one: +$2; or draw
until you have 5 cards in hand.
Polymorph
Action: $2P
+1 Action
Return the top card of your deck to the supply. Gain a card
with the same cost as the returned card, putting it into your hand.
Not much has changed since that 2014 expansion, but this will act as the official thread for my set from this point on. Feel free to make suggestions, test the cards and tell me what you found, etc.
