What are your favorite cards (or events/landmarks), and why? We had a similar topic
two years ago, but a lot of new cards have come out (and become available online) since then. My top 10:
Villa: to me, this is the most unique and mind-bending card in Dominion.
Black Market: adds so much variety and crazy situations to the game.
Watchtower: rewards a player who can utilize its many synergies. Elegant design.
Menagerie: requires work to set up but has great potential. Perfectly embodies Cornucopia.
Tactician: I love double Tactician decks, and even a single Tactician shows that one great turn is often better than two regular turns.
Enchantress: The flavor is perfect, and it discourages strategies focused on a single action card.
Crown: one of the most flexible cards in the game, and being an Action-Treasure causes many interesting interactions.
Procession: It can be incredibly powerful, but requires a lot of care to use correctly.
Transmogrify: kick-starting your engine, milling Provinces, getting rid of Estates, Transmogrify can do it all! .
Castles: a pile that has 8 different cards in it, and works!
Honorable Mention: Counterfeit, Courtier, Replace
