Naydra of the Frozen Peaks

Flying, shroud, freeze
Naydra of the Frozen Peaks enters the battlefield
with 3 scale counters on it.
If Naydra of the Frozen Peaks would be dealt
damage, instead remove a scale counter and
create a Naydra's Scale artifact token with
"{t}, Sacrifice Naydra's Scale: Target
creature gains freeze until end of turn."
