Came here from Tankmas 2022, since that game's Yule Duel isn't working.
A pretty damn fun card game from start to finish. Didn't feel there was much depth for most of my playthrough, but when Santa broke out The Boss, I remembered the rule about 1's beating A's and used it to turn his own card against him. I felt like a goddamn genius after that.
(Protip: Secularism is shockingly strong against Santa.)
