Vigean Intuition
Card draw with a tax: name a type, dig four deep, and pay for the cards you wanted by milling the cards you did not. The design trades raw card advantage for a self-imposed sorting cost, and the cost is real because all four cards are revealed before they are split. A creature deck that calls "creature" might mill three lands and net a single body; a control shell that wants instants accepts the same gamble in reverse. What separates this from a clean draw spell is that the player never gets to keep the spread: every card off the type you did not choose goes straight to the bin, which turns a digging tool into a graveyard-filling one almost by accident. That second function is the more interesting half. Pair it with reanimation, threshold, or any payoff that values a stocked graveyard, and the lopsided splits invert from downside to upside: name the type you want in hand, dump everything else where you can still use it. Read straight, it is a hedged card-draw instant that forces a type choice before the yield is known. Read against a graveyard payoff, it is a fill-and-fetch effect wearing the costume of a draw spell, and the friction between those two readings is what the design is built on.
