Theres even cEDH uses of this card in Kodama of the East Tree decks (which seems like it must be a meme but kind of isnt!)
The lack of Elvish Mystic or Delver of Secrets means that those lands wont be helping to power out extremely aggressive starts with whatever color of mana you need at the early stage of the game, but that doesnt mean theyll be any less played
The only issue with this deck is that it doesnt have a ton of cards that are still competitively viable today (with a few notable exceptions like Lefou Instigator and Shield of Virtue)
As long as neither player is manipulating their library or using their graveyard, using a Millstone does nothing but reveal information until the player being milled runs out of cards, but it took more explanation than you can possibly imagine to make players understand this
theyre unique, silver-border cards designed specifically as a gift for Wizards employees and WPN stores, rife with art and mechanics and puns that bring that holiday cheer to a slip of cardboard near you
Putting the burden counters on the player might have done it
