The first version is clear whereas the second wording is stylistically awkward.
Thank you for your feedback.
As I saw in Dominion cards, every time you are referring to action cards, you need to include the word "cards' to make it clear that you are not talking about remaining rights to do actions.
So, I thougt to write:
(1) "If you have more Actions cards than Treasures in play..."
However, I was in doubt if with this wording it was clear that the "in play' is referring to the action cards or only to the treasures. So, I thought to write:
(2) "If you have more Actions cards in play than Treasures in play..."
I didn't like the repetition of "in play' in this version, so I came with:
(3) "if you have in play more Action cards than Treasures..."
Please help me with this, what is the better wording to make clear the idea without being ambiguous? As I said, english is not my native language.
