The card states, "Put 1 ally card into play from your hand. At the end of the phase, if that ally is still in play, return it to your hand."
The cost of the card is only 1. Now, can I pay the 1 resource and put any Ally of any cost into play for free? Or do I still need to also pay the resource for the cost of the Ally?
Also, maybe I'm not doing it right, but this seems useless since this is an action card and actions are always after important events so putting this out, the Ally won't be around too long in the phase to make any difference?
