City of Secrets reads:

When revealed,shuffle the top X cards of your discard pile back into your deck. X is the number of City plots in your used pile.

So, if I have 0 city plot cards in my used pile (or if I have 0 cards in my discard pile), do I get to shuffle 0 cards back into my deck, thus effectively shuffling my deck? Or am I not allowed to suffle the deck when I cannot shuffle cards back in it?

I wish the search function worked better for this. This goes back to an argument I was having with Bomb on Shuffle(0) vs. Shuffle(Null).

I am unsure of TO concensus at the moment, but will talk theory on it.

In this instance, it is a clear Shuffle(0) due to using a variable of X and that variable being clearly defined as 0. This means that you should be forced to shuffle 0 cards from your discard pile back into your deck (a. k. a. forced to shuffle your deck).

Thanks for the reply!

As I share your frustration towards the FFGForums search engine, I did my homework and found a way to use Google to search inside the FFG website: in the google search box you type your search keywords followed by "site:http://www.fantasyflightgames.com/" without the quotation marks and you should be given more results than when searching with the native FFG search engine.

This way I think I found a topic relating to the discussion you are talking about (link)

The tip about the search engine should be in the Guide to Forum Use, don't you think?

Again, thanks for the reply.

Holy cow!

This is an awesome tip!!!

I think that thread leans towards you don't have to shuffle, so I'd go with that as current TO concensus. Thanks for finding it!
