What to cut, what to add, and how to play the Jund land-sacrifice precon from Edge of Eternities, commanded by Hearthhull, the Worldseed.
Edge of Eternities
World Shaper
Sacrifice-and-regrow lands takes some sequencing. Out of the box, before any upgrades. How we rate precons
Buy World Shaper on TCGplayer →Quick verdict
World Shaper is a lands deck that treats every land as something to sacrifice and play again. Hearthhull, the Worldseed draws two cards each time you sacrifice a land to it, and once fully stationed it drains each opponent for 2 per land you sacrifice. The box has strong payoffs for that in Titania, Protector of Argoth , The Gitrog Monster and Korvold, Fae-Cursed King . It is held back by a commander that needs creatures to station it, few free ways to sacrifice lands, and some expensive or symmetrical cards that don't help the engine.
TurnZero HQ rates World Shaper a 3 out of 5 on difficulty and a 3 out of 5 on power, as it comes in the box. That is our editorial read, not an official Wizards rating. The full hundred cards are on the World Shaper decklist page, and every other precon we cover is on the precon directory.
How the precon plays
Hearthhull, the Worldseed is a four-mana Spacecraft, so it starts as an artifact, not a creature. You station it by tapping another creature you control at sorcery speed, which adds charge counters equal to that creature's power. At 2 counters it gains an ability: {1}, tap it and sacrifice a land to draw two cards and play an extra land that turn. At 8 counters it becomes a 6/7 with flying, vigilance and haste, and each land you sacrifice makes each opponent lose 2 life.
The rest of the deck pays you for lands hitting the graveyard and gets them back. Titania, Protector of Argoth makes a 5/3 for each land that goes from the battlefield to the graveyard, The Gitrog Monster draws a card whenever land cards go to your graveyard, and Szarel, Genesis Shepherd and Exploration Broodship let you play lands again. Fetch-style lands like Evolving Wilds , Fabled Passage and Riveteers Overlook sacrifice lands for free.
The ramp leans the same way. Harrow , Roiling Regrowth and Springbloom Druid sacrifice a land to fetch two, which counts as a sacrifice for Hearthhull and Titania, and Splendid Reclamation or Aftermath Analyst return every land in your graveyard at once.
What works out of the box
Hearthhull, the Worldseed ↗
Sacrifices a land to draw two at only 2 charge counters, and drains each opponent for 2 per land you sacrifice once it is fully stationed.
Titania, Protector of Argoth ↗
Returns a land when it enters and makes a 5/3 Elemental whenever a land you control goes to the graveyard. Every fetch land becomes a creature.
The Gitrog Monster ↗
A five-mana 6/6 deathtouch that draws a card whenever land cards go to your graveyard and lets you play an extra land. Its upkeep cost is a land sacrifice, which this deck wants anyway.
Korvold, Fae-Cursed King ↗
Draws a card and grows whenever you sacrifice any permanent. In a deck that sacrifices lands every turn, it draws several cards a turn cycle.
Splendid Reclamation ↗
Four mana to return every land card in your graveyard to the battlefield. After a few turns of sacrificing lands, this is a huge ramp turn and a wave of landfall triggers.
Szarel, Genesis Shepherd ↗
Lets you play lands from your graveyard, so each sacrificed land can come back. It also adds counters whenever you sacrifice a nontoken permanent on your turn.
What needs improvement
Hearthhull needs creatures before it does anything, because only another creature can station it. Many of the box's early creatures are small, so reaching 8 charge counters can take several turns. Meanwhile the deck has few repeatable, free ways to sacrifice lands outside of Hearthhull's own two-counter ability.
Some slots fight the plan. Blasphemous Act and Gaze of Granite destroy your own creatures and, for Gaze, often Hearthhull itself. World Breaker costs seven, and Eumidian Wastewaker makes you discard or sacrifice too. See how many board wipes a Commander deck needs for how to weigh that.
Upgrade ideas
Each upgrade below starts from something the deck does poorly and says what a replacement card has to do. The cards named are examples, not the only answer: if you own something else that does the same job, or a newer printing does it better, it goes in the same slot. Make one change at a time and play a few games between them, so you can tell which change helped. The general method is in how to upgrade a Commander precon →
1. Sacrifice and replay lands for free
Every land you sacrifice triggers Titania, Gitrog and a fully stationed Hearthhull. A free outlet and a way to keep replaying lands turn those payoffs on whenever you want.
What to look for Permanents that let you sacrifice lands at no mana cost, or that let you play lands from your graveyard or return them to hand.
Cut, for example
Groundskeeper A 1/1 that returns a basic land from your graveyard to your hand for two mana. It is slow, and Szarel and the cards below do it better.
Rakdos Charm Exile a graveyard, destroy an artifact, or ping each creature's controller. Each mode is narrow, and the box already has Bojuka Bog and Tear Asunder for the first two.
Add, for example
Zuran Orb ↗
Zero mana: sacrifice a land to gain 2 life, any time. With Hearthhull at 8 counters, each activation also drains each opponent for 2.
Crucible of Worlds ↗
Three mana: you may play lands from your graveyard. A second copy of Szarel's best ability that is not a creature.
Life from the Loam ↗
Returns up to three lands from your graveyard to hand, and dredge brings it back instead of a draw. It keeps your land drops coming every turn.
2. Protect your board instead of wiping it
This deck builds a board of Elemental and Beast tokens off its lands. Two of its wipes kill that board, and nothing in the box protects it from an opponent's wipe.
What to look for Cheap instants that make your creatures indestructible or regenerate them, so you can hold mana up while still sacrificing lands.
Cut, for example
Blasphemous Act Deals 13 damage to each creature, yours included. Planetary Annihilation is the better reset here, since it also sends a pile of lands to your graveyard.
Gaze of Granite Destroys every nonland permanent with mana value X or less. At X of 4 or more it destroys Hearthhull too.
Add, for example
3. Ramp with cheap creatures that also station
Hearthhull needs creatures to tap for station, and the deck wants extra land drops. Cheap creatures that do both get Hearthhull online earlier.
What to look for Two- or three-mana creatures that give extra land drops or add mana on landfall.
Cut, for example
World Breaker Seven mana for a 5/7 that exiles a land or noncreature permanent on cast. It is too expensive for what it does in this deck.
Eumidian Wastewaker Makes you and the defending player each discard or sacrifice when it attacks. The symmetry costs you a card as often as it costs them.
Add, for example
Lotus Cobra ↗
Two mana: adds one mana of any color whenever a land enters under your control. Fetch lands and extra land drops make it a ramp engine.
Azusa, Lost but Seeking ↗
Three mana: play two additional lands each turn. With Hearthhull's draw and Szarel's graveyard lands, you will have lands to play.
Dryad of the Ilysian Grove ↗
Three mana for an extra land drop each turn and a 2/4 body to station with. It also makes every land every basic land type, which fixes your colors.
4. Untap your dual lands
Three dual lands enter tapped every time. The deck's fetch effects like Nature's Lore and Mountain Valley can find any land with the right type, so shocklands make every fetch better.
What to look for Dual lands with basic land types that can enter untapped, so your fetch spells and lands can find them.
Cut, for example
Canyon Slough A Swamp Mountain that always enters tapped. Cycling it puts a land in the graveyard, but a tapped land on turn two costs more.
Sheltered Thicket The same tapped cycling land in red-green.
Win conditions
The deck wins by turning land sacrifices into damage and creatures. A fully stationed Hearthhull drains each opponent for 2 per land, and Titania, Rampaging Baloths and Omnath, Locus of Rage fill the board with large tokens. Moraug, Fury of Akoum gives an extra combat for each land you play in your main phase. Planetary Annihilation is a reset that suits this deck, since Titania, Gitrog and Splendid Reclamation turn the lands it sends to your graveyard into value.
Who should buy this precon
A good fit for a player with some Commander games behind them who enjoys a lot of small decisions. You track charge counters, decide which land to sacrifice and when, and sequence land drops around several triggers. It is not hard to learn, but it rewards careful play more than a straightforward creature deck.
