Creature — Human Werewolf
At the beginning of each upkeep, if no spells were cast last turn, transform Afflicted Deserter.

You choose the target artifact when Werewolf Ransacker’s first triggered ability goes on the stack. You choose whether or not to destroy the artifact when that ability resolves.
If something becomes a copy of Werewolf Ransacker, that doesn’t count as “transforming into Werewolf Ransacker.” The first triggered ability of the new Werewolf Ransacker doesn’t trigger.
