Me and my group had a discussion last night. I was playing the Naturalist and we were fighting Infinitor. Infinitor played a card that made the hero with the most cards can't play cards. That card stayed in play until it was detroyed. Don't know the name of the card anymore. It was some sort of cage.
So i was dissabled for the time being. A friend of mine asked me if could play a power. I said yes, but that power makes me search my deck for a from card and put it in play. So i could not do that because it count's as playing a card.
He and the rest at the table were not convinced that correct.
So my question realy is, does putting a card in play as a cause of a power counts as playing a card?
No, as a matter of fact. "Put it into play" is actually a completely different action than playing a card, and is specifically meant to get around "can't play cards". So it's not the power so much as the wording that allows you to get that form out.
Just to agree with Takewalker, if you compare Expatriette's base power to The Naturalist's base power, you can see the difference in wording. If in the same position as you describe, Expatriette could not play a card via her power.
This game is extremely literal. Since you power did not actually say that you were playing that card, then that power does not in fact play a card. It does not matter that the effect is the same, only in what the exact wording is.
