So if "Your Estates turn into another card" does that mean they literally inherit the card text? So your Sir Martin Estates attack like a Knight, but if you are attacked by a Knight, Sir Martin the Green escapes because he only costs $2?
But if you put your Estate token on Treasure Map, that means you can collide two "Estates" with each other or one with a real Treasure Map and trash both cards just las if they were real?
"Your Estates turn into another card" is a convenient inaccurate shorthand. Your Estates gain the abilities and types of the card. They don't copy anything else, including cost, or name, or "what pile was that from."
So Sir Martin Estates have the types of Sir Martin, and give +2 Buys and attack like he does. They can die to other Knights if they hit one, but other Knights attacking skip over them since they cost $2.
Your Estates gain the abilities of Treasure Map but are Estates rather than Treasure Maps, so they don't find you any treasure.
Thanks; that was really useful. I understand there will a FAQ on this, but, in general, I can see where if card text refers to the card name, and it ain't "Estate", then you're all done. Is the use of the word "this" neutral enough for you to play "as if" it were the same card?
So specifically, Urchin's card text reads:
When you play another Attack card with this in play, you may trash this. If you do, gain a Mercenary from the Mercenary pile.This leads me to believe that if you put your Estate token on Urchin, you can trash an Estate played as an attack if you play another attack (which could be another Estate played as if it were an Urchin). Is that right?
(Note: I have no idea whether this is just a Fancy Play most of the time, but the idea of Turn 2 Mercenary in contrived circumstances is amusing.)
And then there's cases like Pirate Ship, whose text reads:
Choose one: Each other player reveals the top 2 cards of his deck, trashes a revealed Treasure that you choose, discards the rest, and if anyone trashed a Treasure you take a Coin token; or, +$1 per Coin token you’ve taken with Pirate Ships this game.(Emphasis added by me.) In this case, it seems like if you put your Estate token on Pirate ship, that you can take choice 1...but then have to put the Coin token gained some place that's not the Pirate Ship mat since the second choice tells you that only Coin tokens "taken with Pirate Ship" yield money. But by the same token (heh), maybe you
can play Estate and take the second option and get money for the tokens on your Pirate Ship mat, if there are any. (Again, no suggestion you would actually want to do that, but...seems possible.
