Gandalf's Staff was a powerful item when it was released and much speculation occurred Oger what a possible Radagast Staff would be. I don't think anyone is dissapointed in this final incarnation.
Three choices, all of them excellent. Readying a jacked up Eagles of the Misty Mountain or reducing its cost to get it into play in the first place are both fine options. And some random Lore trap synergy with the returning creature the staging area. All in all excellent!
