Graven Lore

The draw-three portion is fixed; it's the scry that snow pays for. Cast off unfiltered mana and this is a five-mana refill that filters nothing before the cards land, a poor rate for a spell at this cost. Fill your mana base with snow permanents and every snow source you tap deepens the dig, letting you scry through your whole draw and then some before the three cards arrive. That structure is the point: it turns manabase construction into a lever on the spell's quality, rewarding a deck that has committed to snow at the land level rather than treating it as flavor. The scry-then-draw ordering matters more than it looks, since you smooth first and commit second, so a high snow count lets you bury a fistful of dead cards and effectively draw the best three of a much larger window. It belongs to the small family of cards that make snow mana a resource with a payoff attached rather than a cosmetic subtype, and it does the work at instant speed, so the digging happens on the opponent's end step when you already know what you need. The floor is a clunky refill; the ceiling is a deck-defining selection engine, and the distance between them is entirely a deckbuilding decision made long before the card is in hand.
