Please check my logic:
Step 2 of Setup is "Place Heroes"
This would put Hero Faramir into play
Step 7 of Setup is "Follow Scenario Setup Instructions
At this point Blood of Gondor Stage 1A would occur
"... Put the Faramir and Lord Alcaron objective allies into play."
The unique card rules states:
"If any player has a unique card in play, no player can
play or put into play another card with the same title.
Any attempt to do so will fail to the extent that the card
attempting to enter play remains in its current location
(hand, deck, discard pile) and does not enter play."
Basically, this setup step would backfire and only Alcaron would enter play.
Not sure why someone would do this. Maybe they really want to use the Faramir ally.
