My favorite card is tournament.
In games with tournament I'm more interested in winning prizes than actually winning the game.
I like the tricky to trigger concept and unique cards with no other way to get them.
So here's my submission: the Lost City Explorer
And the Lost Cities:
They're a little wordy, Should probably get simplified down.
Firstly,
I LOVE THIS IDEA SO MUCH.
Secondly, mechanics:
I'd recommend switching the +1 Card and +1 Action on LCE. Donald X. explained in the secret history that Tournament used to not give +1 Action when another player revealed a Province, but it was no fun since you'd be stuck wondering whether you should risk your last Action on Tournament or not.
In terms of the lost cities, I honestly think they're all way too overpowered. To be concise: El Dorado, FoY , and SL are
probably fine by comparison. Don't get me wrong, though. They're still really strong. They just aren't game-ending. Meanwhile, Atlantis is absurdly broken in any context and Machu Picchu is a big "fuck you" to your opponent if they spent all turn making an Engine deck. In that case it's basically an instant win card.
Thirdly, presentation:
VP amounts should be under what the card does when played. So Atlantis' and FoY's top and middle should be switched. El Dorado should be flipped. Machu Picchu's first segment should go after its (current) third one, and the (current) second and third segments should be combined since Duration effects don't cause a dividing line.
Fourthly, wording:
Atlantis should read "Gain
a card to your hand" (*cough* overpowered *cough*) since "gain a card" implies that the restriction that gained cards have to be from the Supply is in place, whereas saying "gain any card" implies that that restriction is out the window and you can also gain the card from your opponents' cards, the Trash, the Lost City pile, etc.
The bottom should also be something more concrete and not subject to interpretation. For example, if you moated (or didn't moat) an Attack and that caused your opponent to change their strategy and end the game, did
you end the game? It needs to be less vague and more measurable, for example:
If the game ends on your turn, trash this before scoring
Or:
When the game ends, if you were the last player to gain a card, look through your cards and trash this.
El Dorado should say "costs", not "cost"
There should be a comma in Machu Picchu's bottom. The wording in its (currently) third part (*cough* overpowered *cough*) is also extremely vague. Opponents can only play one Action card? Is that one Action each or one Action total? What if they play a Throne Room? Can they play another Action with it? I recommend the unambiguous "during each other player's turn, they ignore any +Actions they get".
Shangri-La should read "Worth 1% per...", not "1% per..." to keep it consistent with cards like Gardens.
Oh and of course finally: There's already a card called Lost City. Just something to keep in mind. I love the flavor though.
