But only from the available reinforcements right? Not from the dead pile.
Personally I'd prefer if the card allowed the recruiting of a North unit (doesn't matter what the composition of the army is), without the need to remove a regular at all, which would then reflect the event from the book - the Rangers of the North ... Nigel
I think the game designers have made a tiny mistake here, which can however be rectified by a simple house rule. Remember, Halbarad and the thirty Rangers of the North, along with Elrond's twin sons, Elladan and Elrohir, should be an addition to the army, not a substitute. As such, they should not count towards the figure limit of elites that can be recruited by any one nation. My solution is to allow the elite figure their upgrade produces to be taken from the pile of dead, if possible, of the nation they join.
