Warspirit of Skadi

All cards with "wolf" in the subtype name
gain frostbite. (Whenever this creature deals damage to a creature, tap that creature. It
doesn't untap during its controller's next untap
step.)
"The blizzard blows in a terrible frost. It covers
all and leaves nothing but an icy echo." -Griffig, the Hermit of Mount Kalystor
