Barrowgoyf grows quickly against Elves' go-wide creature strategy since so many permanent types hit the graveyard, and its deathtouch/lifelink let it trade favorably or stabilize against a Craterhoof Behemoth-fueled alpha strike. Portable Hole can exile their mana dorks (Elvish Mystic, Llanowar Elves, Fyndhorn Elves) or a cheap Quirion Ranger before they generate overwhelming mana. We cut Personal Tutor and Flow State since this matchup is a race where their Natural Order into Craterhoof can end the game fast, and we need bodies and removal more than extra card selection. Keep Fatal Push for their small creatures and Thoughtseize to strip a key piece like Natural Order.
