So basically, I want to have a unit attached to Great Book of Grudges while I have a Grudge Thrower and Reclaim the Hold in play. I sac to the grudge thrower, triggering great book of grudges, can I use reclaim the hold to turn that unit and great book of grudges into developments so I can pick them back up using abandoned mine? I think Reclaim the Hold needs better wording.
As I read it, "... you may discard 1 resource token from this card to place that card into its current zone as a development instead of discarding it"
So the question is, does it hit the discard pile, thus triggering great book of grudges, then via reclaim the hold it's now a development?
