I am relatively sure that "(+1 action has no effect if it is not your turn) does NOT mean anything at all in terms of the way the card works. It is simply a reminder that you don't get any benefit from the extra action. It's not saying that the "+1 action" part of the card is ignored completely. Among other things, the text is in italics. Do any other cards use text in italics anywhere? I'm pretty sure there's a couple, but can't think of / find any. But if there are any, I'm almost positive that it is not text that actually changes any rules at all; it's simply a clarification/reminder.
I do agree that the text is a reminder. It doesn't define what the card does, just as Native Village wouldn't work differently without the "return them to your deck" part. After all, i allready expressed that i think calling Coin of the Realm will follow the same restrictions without the wording. The paragraph just reminds us of a general rule that some people might believe this card conflicts with, and the question is which rule that is. I say it's the fact that you get actions during your action phase, and never else. You believe that those actions hang around and just can't be used.
Honestly that notion puzzles me. After all, when do those extra actions disappear? At the start of your turn? At the end of the current player's turn? Or his buy phase, even? And, why would Caravan Guard remind us of something by saying something different and - according to you all - simply false? Why doesn't it say something like "Having actions doesn't allow you to play actions when it's not your turn"? How can you seriously say that when a reminder text says what i say it has to be ignored for the purpose of believing into something it doesn't say and that's never said elsewhere?
Thanks Accatitippi, that's my point.
