Not sure why you would call these mistakes. Redundancy can be very helpful and, going back to topic, if the text on Expert Tracker had explicitly mentioned "you control" too, you would not have misinterpreted it in the first place.

I simply do not understand the different wording for the same effect. If the game rules dictate that you may never exhaust/discard/etc. other player's cards by your card effects, no card of that kind should EVER read "you control". Or, alternatively, they all should read "you control". Not random half of them.

When an enemy makes an additional attack, it always gets a shadow card. Many older enemy cards had a parenthetical, "deal a shadow card for this attack." Also redundant. It is what it is. Write a letter to the developers if you feel strongly about it.

Yes, "many older". Emphasis on "older", yet we have this kind of wording on Helm! Helm!. No letters written to the developers transform text on the existing cards.

Complaining doesn't change card text either.

...so, what do you want?

Yes. You know what does? Being consistent in your cards texts as a game designer.

I want you to aknowledge that the wording currently used is wrong and an act of poor writted card text consistency. And to stop defending it, at least.

Ohhh, you want US to do something for you.

Meh, I'm not offended by this card text. Try someone else.

I do not want anything from the US government.

I think we all agree it is redundant and inconsistent but the intent is clear (as defined by whether or not an FAQ response is required). I'm not sure what else you are looking for. Whether you think that makes the card wrong and/or poorly written is subjective. It seems pretty typical to me. Not as well written as Magic, but better than the Pathfinder Adventure Card Game or anything you'll get from Kickstarter. I don't know how it compares to other FFG LCGs.

Several people already admitted it was refundant. Your request has been completely satisfied.

It is annoying that wording on cards differs and is not consistent however I messaged Caleb and then realised when he replied it is indeed outlined in the core set rules booklet so is pretty clear:

"Many cards are written in a “pay or exhaust X to do Y” manner. When confronted with such a construct, everything before the word “to” is considered the cost, and everything after the word “to” is considered an effect. Costs can only be payed with cards or resources that a player controls. If an effect is canceled, the cost is still considered to have been paid."

(taken directly from core set rulebook under "paying costs")

Caleb's response:

Hi Gello,

You can only exhaust characters you control to pay the cost for an event you play.
Cheers,
Caleb
