Archaeologist
Types: Landmark
When scoring, 1/3/6/10/15 VP if you have 1/2/3/4/5 copies of a particular Ruins.
Setup: Put a Ruins face-up sideways on each Kingdom pile. When a player gains the first card from a Kingdom pile, they also gain the Ruins on top of it.
Even not taken into account the usage of ruins, I am not a huge fan of the first mover advantage on this.
Burial Grounds
Types: Landmark
When scoring, -3 VP for each differently named card in your deck which has a copy in the trash.
Burial Mounds
Types: Landmark
When scoring, 3 VP per differently named card in the trash that you have a copy of.
Well... 2 people really need to come forward and explain this coincidence, haha. Either way, not a huge fan of either concept. I tried thinking about doing anything with the trash, but nothing really stuck out. This particular examples don't really show me otherwise. The first one: when you can trash copper, you'll trash all the copper. The second one: even if you can trash copper, it's not that difficult to keep one copper. Either way, not a huge fan. I am trying to imagine fun game interactions, but I am just not seeing it.
I did like Conman's point on Grounds: " I suppose it's an incentive to throw a few engine pieces in the trash in the hopes of catching your opponent out." Maybe Bural Grounds should be restricted to action cards, so you can only use it strategically in that sense, which is awesome. On the other hand, maybe that just incentivizes BM, which is bad.
Cenotaph
Types: Landmark
During Clean-up, you may place one card you discard from play or your hand face down underneath this.
When scoring, 1 VP per differently named card underneath this that you have a copy of.
Clarification: You may place one card underneath Cenotaph every turn.
This is slightly better, I think, but there should be some kind of penalty, I think, otherwise it's just a free trasher, even without the vp gaining.
Citadel
Types: Landmark
When scoring, 1 VP per card in your deck which no other player has a copy of.
A bit lackluser. I think I'll probably like it more if it was slightly more VP.
Deep Mine
Types: Landmark
Whenever a player plays their second action in a single turn, move 1 VP from the Province pile to here.
Whenever a player ends their turn without having played any action cards, take the VP from here.
Setup: Put 8 VP on the Province pile, plus 2 VP per player.
This one I do like, although it probably, again, incentivizes playing BM versus a non-bm player, which is bad.
Golden Isles
Types: Landmark
During each player's buy phase, they may return 1 VP token for +$1. This may only be done once per turn.
When scoring, 4 VP if you have no VP tokens, and 2 VP if you have fewer than 2 VP tokens.
Setup: Each player receives 13 VP tokens at start of game.
Using VP for $ is interesting. I am just not sure if it works.
Middle Class
Types: Landmark
When scoring, 1 VP per non-Treasure card costing exactly $3 in your deck.
Too much like an outtake and a little bit uninspiring.
New World
Types: Landmark
When scoring, if there are 2 or fewer empty Supply piles, -4 VP for each Victory card costing $6 or more in your deck.
I usually hate 3 pile endings, but this is an hilarious way of actually forcing it. I do think I like it, because it's so cruel. Playing with this landmark in a game where 3 pile endings would be weird is hilarious.
Ossuary
Types: Landmark
When scoring, the most common card in the trash is worth +1 VP. (If it's a tie, all tied cards are.)
Setup: Trash a Duchy.
Cute set up. But again: making coppers worth something is meh. I guess it's only cool in non-estate, non-copper trashing games, imo. Everything else it just feels meh.
Plains
Types: Landmark
Whenever you gain a Victory card, move 2 VP from its pile to this. When you gain a Province, take the VP from this.
Setup: Put 4 VP on each non-Gathering, non-Province Victory card Supply pile per player.
A bit uninspiring. To me, the idea of VP is to get VP in a different way, not more VP when you buy V cards.
Rally
Types: Landmark
Once during an opponents turn, when all of your opponent's cards are either in play or in their hand, take 1 VP from here.
Setup: Put 6 VP here per player.
Cute. Not wow, but ok. Less accounting than philosopher's stone, so that's cool.
Sacrificial Cenote
Types: Landmark
Whenever you resolve an attack which ends up doing nothing to other players, or otherwise resolve a card that is prevented from having its printed effect, +1 VP.
Sounds like it'll need a large faq, but I guess it's not strictly impossible to define what it means, right. So I am going to give it the benefit of the doubt.
Senate
Types: Landmark
At the start of your Buy phase, if you have no cards in your deck and at least one card in your discard pile, take 2 VP from here.
Setup: Put 6 VP here per player.
A bit bland, but it works on an unusual thing, so that's good.
Statue
Types: Landmark
At the end of your turn, if you played 5 or more treasures that turn, take 2 VP from here.
Setup: Put 6 VP here per player.
Needs less BM.
Stockpile
Types: Landmark
When you buy a card costing at least $5, you may take it's price in debt. If you do, +3 VP.
Could have been an event (as some have mentioned), and does give the last province buy +3 free VP. But besides that, I think it'll create interesting discussions. I don't think it'll get out of hand too much: If you use this and you want to buy use this a second time, well, that's at least $15 you'd need, for 6 VP. Paying $10 for a $5 card and a duchy seems reasonable enough, but do you really want the 3VP now or build some more to get more stuff later?
Swamp
Types: Landmark
When scoring, 1 VP per Victory card you have.
Very bland, but I do think it works.
Symposium
Types: Landmark
Once per game, at any time during the Action phase, +1 Action.
At the end of the game, if you did not use that Action, +5 VP.
I like where this is going, but I don't think it's there yet.
Turtle Sanctuary
Types: Landmark
When you reshuffle, -1 VP.
At the end of your turn, if you did not reshuffle this turn, +1 VP
Clarification: -1 VP means you return one of your VP tokens to the supply. If you do not have any VP tokens, do nothing.
Slogdecks like it. That's an interesting thing.
