Iceborn Draugr

Flying, Menace
Freezing 3 (Whenever Iceborn Draugr deals damage to a creature, put 3 freeze counters on that creature. Creatures with freeze counters on them can't untap, attack, block, or activate abilities. Each player removes a freeze counter from each creature with a freeze counter on it at the beginning of their upkeep.)
Fell magics revived those lost in the icy wastes as Ragnarok raged on.
