The Wild Hunt Navigator effect is listed as
Deploy: Summon a copy of a different Bronze Wild Hunt Ally
I played a few games with a Monsters deck, but I don't think I understand the restrictions on this particular card. In a few cases where I tried to use it, it simply didn't do anything.
I'm probably misunderstanding some aspects of this ability, so how exactly does this card work? Which cards can I copy and which other conditions must be fulfilled for this card to work?
