Grýla is a Christmas witch from Icelandic folklore. She wanders from village to village begging for food and naughty children. She has a cat familiar and thirteen mischievous sons, the Yule Lads. Wander from village to village, setting hamlets and castles ablaze while wreaking havoc with impish minions (faeries for synergy with sylvan splendor). Take advantage of Witch’s ability to cast Black Knight for reduced mana. Throw a snowball or two. Exchange a lump of coal (just a rock) for something valuable. Maybe win a game here and there. Merry Christmas!
