I covered some of how I'd categorized them here...
https://www.boardgamegeek.com/thread/1889010/dominion-empires-10th-expansion-has-less-cards-add... feel free to use that as a reference, but I'll just keep things non-categorized for this thread.
======== LIKES ======== Palace - I like how buying Treasure can get you points, and these can provide tension of whetehr you'd rather get Platinum/alternative Treasure, or the standard Trifecta. Plus, it causes a 'hard decision' in games where you can still do a bit of Trashing (though not compared to completely stripping away all/most of your Coppers)
Fountain - Like another take on Gardens, and quite a lot of pts to boot!
Baths - when there is something to buy, it's nice to make a harder decision of whether or not you should. When there isn't anything meaningful to do, taking in the 2pts is nice!
Obelisk - Can make ordinary cards extraordinary. Also, they're functionally VP, but since most of these are NOT hybrid with Victory type/keyword, many of the restrictions that applied to gaining Victory cards aren't an issue here
Basilica - Sort of an homage to Guild's Overpay mechanic. Here, you either overpay by 2+, or not, but still gives you a reason to try to set up having more coins than not.
Tomb - always a fan of trashing
Museum - I tend to like to get variety anyways
======== DISLIKES ========Keep - creates tension in keeping track of Treasures, if you should hold on to some of them (esp. the alternative Treasures), and if you should go for tying to get pts, or going further to deny those 5pts. Ditto with just keeping track of other players' decks in general... I'm kinda lousy at being able to do that well. I can keep track of stuff in my own deck (barely), but other players'... esp. 4p games... tracking Provinces took some practice to get down, and even then, it's still not fully certain
Wolf Den - I'm pretty lousy at tracking this
