Hearthhull, the Worldseed anchors a Jund lands deck. It sacrifices lands over and over through fetchlands, sacrifice-lands, land-sacrifice ramp spells and outlets, and replays them from the graveyard with extra land drops. Each sacrifice makes Hearthhull drain every opponent for 2, and each replayed land sets off a wide spread of landfall payoffs, some of them doubled. Hearthhull's own station ability turns lands into cards and extra land drops, so the loop of sacrifice, recur and replay both refuels the hand and grinds the table down. How it wins: Repeated land sacrifices and land drops pile up Hearthhull drains and landfall pings, burn and life loss across all opponents, sometimes finished by a flying Hearthhull, a huge Korvold or mass land-reanimation turns. Key roles: - Land sacrifice outlets: Fetchlands, self-sacrificing bounce lands, ramp spells with sacrifice costs and free sacrifice outlets each turn a land into a 2-life drain from Hearthhull, while often thinning the deck or making mana (Zuran Orb, Nahiri's Lithoforming, Scapeshift). - Graveyard land recursion: Permanent effects that let lands be played from the graveyard, plus mass land returns and Loam-style recursion, keep the sacrificed lands coming back so the loop never runs dry (Crucible of Worlds, Life from the Loam, Splendid Reclamation). - Extra land drops: Permanents granting additional land plays let several recycled lands hit the battlefield each turn, multiplying both drains and landfall triggers (Azusa, Lost but Seeking, Dryad of the Ilysian Grove, Oracle of Mul Daya). - Landfall damage and value: Creatures and enchantments that ping, drain, make tokens or mana whenever a land enters convert every land drop into reach or resources (Ob Nixilis, the Fallen, Valakut Exploration, Tireless Provisioner). - Trigger doublers: Two creatures double triggers caused by lands entering, so each land drop pays out its landfall effects twice (Ancient Greenwarden, Traveling Chocobo). - Sacrifice payoffs and card flow: Cards that reward any sacrifice, or lands hitting the graveyard, draw cards, deal damage or make bodies, turning the land-sacrifice engine into overwhelming card advantage alongside Hearthhull's station draw. Small creatures tap to station Hearthhull (Korvold, Fae-Cursed King, The Gitrog Monster, Mayhem Devil).
