I've just been told about a player cannot play it's last card as a Future Offensive (FO). I thought that it was told about not playing the FO card as the last card. Which interpretation seems right?
The rules says:
B. Future Offensive Card During the Offensives Phase
A Strategy card cannot be played as a future offensive in the same
game turn in which it was designated as a Future Offensive card,
nor as the last card played by the owning player during an Offensives
Phase, either as an Offensive or a Reaction.
You can put down your last card as a Future Offensive.
You cannot play your current Future Offensive card if it is your last card (i.e., no other cards in your hand).
Once you put down a card as a Future Offensive, you cannot then play that card until your next turn.
