Dark Depths (M3C)

Legendary Snow Land

Dark Depths enters with ten ice counters on it. {3}: Remove an ice counter from Dark Depths. When Dark Depths has no ice counters on it, sacrifice it. If you do, create Marit Lage, a legendary 20/20 black Avatar creature token with flying and indestructible.

Essential combo engine and win condition for Legacy and Commander. Dark Depths is one of the most efficient threats in Magic—a single card that generates an unstoppable 20/20 flyer with indestructible, often within the same turn using cost-reduction effects or fast mana. In Legacy, it's the centerpiece of Depths decks and pairs with cards like Thespian's Stage for immediate kills; in Commander, it's a reliable finisher that demands an answer the moment it resolves. An auto-include in any deck with access to colorless mana and ways to accelerate its counter removal.
