This is a lands-sacrifice deck built around Hearthhull, the Worldseed. Every land sacrificed through fetchlands, sac-lands, Harrow effects and sac outlets makes each opponent lose 2 life. Landfall payoffs reward the steady flow of lands onto the battlefield, while recursion keeps replaying the lands that pile up in the graveyard. Hearthhull is stationed by tapping big creatures, and at 2+ it also becomes a repeatable sac outlet that draws two cards and grants an extra land drop. How it wins: It drains opponents 2 life at a time with every land sacrifice, amplified by Mayhem Devil pings, while landfall and graveyard-scaling threats (Beast and Elemental tokens, giant Multani or Uurg, extra combats from Moraug) close out games through combat. Key roles: - Land sacrifice fuel: These cards and land-sac outlets turn each land into repeated drain triggers for Hearthhull, the Worldseed, often netting card advantage or extra mana along the way (Evolving Wilds, Roiling Regrowth, Sprouting Goblin). - Sacrifice payoffs: These creatures punish or profit from every sacrifice by pinging opponents, drawing cards, growing the board or making tokens, which stacks with the commander's drain (Mayhem Devil, Korvold, Fae-Cursed King, Titania, Protector of Argoth). - Landfall and extra land drops: Additional land plays and lands played from the top of the library feed token makers, Clues and extra combats, which converts land volume into board presence (Rampaging Baloths, Omnath, Locus of Rage, Oracle of Mul Daya). - Land recursion loop: Sacrificed and milled lands return from the graveyard individually or en masse, so the drain engine never runs dry and a single spell can retrigger landfall many times (Splendid Reclamation, Szarel, Genesis Shepherd, Soul of Windgrace). - Graveyard-scaling threats: Self-mill fills the graveyard with lands, which pumps creatures and tokens whose size counts land cards there (Multani, Yavimaya's Avatar, Uurg, Spawn of Turg, Formless Genesis). - Stationing bodies: High-power creatures and tokens tap to charge the commander and Exploration Broodship quickly, unlocking the extra land drop, land-sac card draw and casting permanents from the graveyard (Baloth Prime, Exploration Broodship, Hammer of Purphoros).
