What I'd love to see in responses is what you think of each card, how you could see it being played (if it's good), and how much it would probably cost.
sure! I'll be super blunt though, so don't take it too hard.
Blindfolded - Action
Shuffle your hand into your deck.
+5 cards
(I don't know of any existing card that does this.)
The shuffle-hand-into-deck mechanic is, unlike in other games, not interesting in dominion. Drawing a new hand is interesting, but it has already been done, with Minion. The only difference is that this one makes you redraw the cards you just discarded, which is a bad thing, because it makes it so you can't cycle through your deck anymore (like with minion), directly resulting in dead turns.
Crystal Bowling Ball - Action
Reveal the top 2 cards of your deck. Add one to your hand and discard the other.
(Would definitely need +actions attached - maybe 2? That would make it a slightly better Village.)
Super old idea, has been tried/proposed a lot of times. It would be too strong 2 actions, and useless with 0, so it needs to have one. One of the cards in this category I considered was this:
c? - Action - 3/4$
+1 Action
Look at the top 3 cards of your deck. Put one of them into your hand. Discard one. Put one on top of your deck
which looks at 3 instead of 2 and also topdecks one, because why not. I think it'd be fine powerwise, but it just wasn't original/interesting enough for my taste. If you want to try it anyway, start with +1 action and looking at 3 cards, and make it cost 3$ or 4$.
Hippy Toilet - Action
Add one card from your discard pile to your hand.
(Again, probably needs +actions.)
Another old idea. I've actually considered a version of this too:
c? - Action - 3$
+1 Action
Look through your discard pile. You may put a card from it into your hand. If you don't, +1 Card
That's less swingy, and it would probably also be fine, but I decided not to try it. If you do it, I'd make it non-terminal and cost between 2$ and 4$. It's nothing new though.
Inconspicuous Time Machine - Action/Reaction
(don't know what the included action would be)
--
When you discard a card, you may discard this from your hand. If you do, add the card you would have discarded to your hand.
(Kind of a Scheme variant in reaction form.)
I saw this very recently in the fan expansion of someone. I don't remember who it was. His version didn't discard itself though, which I discouraged because it meant that pretty much every sifter was crazy strong in combination with the reaction. I like this version more, because it doesn't make every combination with any sifter a must-go-for.
It is pretty weak though, and it of course needs some kind of top part. I would try to come up with a cheap effect, preferably make it a card costing 2$.
Major Sacrifice - Victory/Reaction
Worth 2VP (maybe?)
--
When this card is trashed, +1 action at the start of your next turn.
(Would 2VP be good? It would have to balance the points vs. the on-trash Village effect.)
This is bad because you'll never buy it, unless you just want the VP's. The on trash is nowhere near good enough to make it worth it. It's also untrackable, which might not be the worst thing, because it's a really simple effect.
Worshipped by Small People - Action/Attack
Name a card. If any opponent has that card in hand, he/she must discard it.
Alternatively: Name a card. If the player to your left has that card in hand, he/she must discard it.
(This would have to be expensive. Overpowered?)
there is consensus in dominion that political effects are strictly forbidden (political = every decision where you have to value one player against another one, you'll notice that every attack in dominion is global for this reason). The second version is political, and therefore a no-go. The first version is something I've been having in my head for a while, but I never went for it. There are just too many problems, like a) it's super strong, b) it's super swingy, c) it can still be political, if you know opponent A has card X and opponent B has card Y. I don't really see a way to solve any of those, so I would not try it.
Gingerdead Man - Action
+2 cards
You may discard up to 2 action cards from your hand.
(I could see this comboing well with Shanty Town but I don't know what else. It might need +actions.)
Well, you probably want it to be terminal and draw 3 cards, because with an Action it's too strong, and as a 2-card terminal effect it's too weak. The problem here is that it's a dud in most games: discarding usually doesn't do anything. Also, restricting it to Action cards is a pretty random idea. You could reward it for discarding Action cards I guess? but that's probably less fun than playing those Action cards.
A somewhat similar idea that someone posted a while ago and that I did like was this:
?? - Action - 5$
+3 Cards.
You may put any number of cards on top of your deck.
this version is more useful, because topdecking > discarding in relevance, and it's more elegant. It's just a little bit weak.
Taste No Evil - Action/Duration
Reveal the top 2 cards of your deck. If you reveal an action card, play it. If you reveal 2 action cards, play one this turn and set the other aside. Play it at the start of your next turn. Discard the other card(s).
Alternatively: Reveal cards from your deck until you reveal 2 action cards. Play one of them. Set aside the other and play it at the start of your next turn. Discard the other cards.
(A Herald/Golem variant.)
The question here is: where is the appeal of this card (version 1) over Herald? It's not really there. Herald already plays cards from the top of your deck, and requires you to have a high Action density to make it work. Your card plays cards from the top of your deck, and requires you to have a high Action density to make it work. The concept is identical, only Herald is properly worded and balanced.
The same goes for the second version, only replace Herald with Golem.
Unicorn Graveyard - Action
Discard all victory cards from your hand.
(The reverse of Scout? It would combo well with handsize increasers. Probably needs +actions.)
Here it's again the problem: you don't want this. If a card is just good for a specific combo, than that combo either needs to be available all the time (like Fortress trashing), or the card needs to make the combo work by itself (like Minion's discard + non-terminal virtual money). This does neither, it'll just be useless in the majority of games. There are only 3 draw-to-x cards in the entire game, the chance of one of them being there is very low.
Element: Stone - Action
Discard a card from your hand.
+3 cards
(Cheap Smithy variant if terminal or pretty nice Lab variant if non-terminal.)
As a Lab variant, it's way too strong (-> Stables). As a smithy variant, it's kind of made unnecessary by courtyard. The best thing I could come up with right now would be to make it non-terminal and discard 2 cards instead of 1. Then you get a sifter that doesn't increase handsize, and would be alright at 5$ I guess. The problem here is, sifter that doesn't increase your handsize at 5$ has been done too, with Cartographer. Making you dicsard first is kind of new. Not terribly excited about it though.
The best idea here is the "discard me to put another discarded card into your hand" imo.
