Xianghua reads:
F: Add 1 attack of printed difficulty 4 or less from your discard pile to your card pool. Only playable once per turn.
Does this allow her to actually play that attack? since it doesnt actually say play, she just seems to be putting it there without it doing anything. Is this ability to not infact play it, but to put an attack into her card pool which has a continuous ability while it is there?
