Emerge MTG: How It Works, All 15 Cards, What to Sacrifice and a $55 Herigast Deck (2026)

Emerge is the Magic: The Gathering keyword that lets you cast a big creature cheaper by sacrificing one you already have. You pay the emerge cost instead of the mana cost, sacrifice a creature, and the cost goes down by that creature’s mana value. Sacrifice a 4-drop to cast Elder Deep-Fiend and you pay {1}{U}{U} instead of eight mana. Only the generic part shrinks: the coloured symbols in the emerge cost always have to be paid.

There are only 15 cards with emerge. Ten came out in Eldritch Moon in 2016, one each in the Doctor Who and Jurassic World sets in 2023, and three in Modern Horizons 3 in 2024. One of those three, Herigast, Erupting Nullkite, gives emerge to every creature spell you cast, which turns the keyword into a Commander strategy. We ran our Herigast deck through 50,000 test games with emerge on and again with it switched off. With emerge, the deck had a creature with mana value 7 or more on the battlefield by turn 5 in 62% of games. Without it: 21%.

This guide covers the emerge rules, what you really pay, what to sacrifice, all 15 cards, the colourless-card trick, the best commanders, legality in every format, how to beat it, and a $55 Herigast Commander deck.

What is emerge in MTG?

Emerge is rule 702.119 of the Comprehensive Rules. Rule 702.119a says emerge “represents two static abilities that function while the spell with emerge is on the stack”:

• An alternative cost. You may cast the spell by paying its emerge cost and sacrificing a creature, rather than paying its mana cost.
• A cost reduction. If you paid the emerge cost, the total cost is reduced by an amount of generic mana equal to the sacrificed creature’s mana value.

Rule 702.119b adds a variant, emerge from [quality]. Crabomination has “emerge from artifact”, so you sacrifice an artifact instead of a creature. Everything else works the same way.

Three things follow from that wording. First, the sacrifice is part of the cost, so it can’t be responded to, and the creature is gone before the spell is even on the stack. Second, the creature still counts as having died, so its “when this dies” triggers go off. Third, emerge is a way of casting, so every “when you cast this spell” trigger on an emerge card still happens. Most of the Eldritch Moon emerge creatures put their best ability there, which is why sacrificing for them feels free.

Emerge rules: 13 common situations

The emerge math: what you actually pay

Here’s the surprise in the census. On 13 of the 15 cards, the emerge cost is exactly one mana less than the mana cost, before you sacrifice anything. Elder Deep-Fiend costs {8} or {5}{U}{U}. Wretched Gryff costs {7} or {5}{U}. So sacrificing a token saves you one mana, and every point of mana value on the creature you sacrifice saves one more. The two exceptions go the other way: Crabomination’s emerge cost is {5}{B}{B} against a mana cost of {4}{B}{B}, and Adipose Offspring’s is {5}{W} against {3}{W}. Both pay you back with an effect that cares about what you sacrificed.

The table shows what three popular emerge cards cost after the sacrifice, plus any creature spell under Herigast (whose emerge cost equals its mana cost).

The pattern to remember: the generic part of the emerge cost is the most mana value you can usefully sacrifice. Above it, you’ve thrown away a bigger creature for nothing. That’s 5 for Elder Deep-Fiend and Wretched Gryff, 6 for Decimator, and the whole mana cost under Herigast. In Commander, 48% of legal creatures have mana value 4 or more, and 13% have 6 or more, so big fodder is rarer than it sounds.

How much faster is a deck with emerge?

We built a 100-card Herigast list (below) and goldfished it 50,000 times: 7-card hands, no mulligans, one land a turn, no opponents. Ramp first, then the biggest creature you can cast. Each game ran twice: once with Herigast’s emerge, and once with emerge switched off so everything, Herigast included, is hard-cast. With emerge, the sim always sacrificed the smallest creature that made the spell affordable, and only if the new creature had a higher mana value. Herigast itself counts as a mana value 7+ creature.

With emerge, Herigast came down on turn 5.4 on average and was out by turn 10 in 96% of games. Hard-cast for {9}, it averaged turn 7.4 and made it by turn 10 in only 54%. Over the first eight turns the deck emerged 1.6 creatures per game and saved about 8 mana doing it. The model leaves out removal, card draw from the deck’s spells and the value of what the fodder leaves behind, so read it as how fast emerge gets big creatures down, not as a win rate.

What to sacrifice to emerge

The best fodder does one of three things: it has already done its job when it entered, it does something when it dies, or it belonged to someone else. A Commander-legal search gives the size of each pool:

• 632 creatures have a “when this creature dies” trigger. Every one of them fires when you emerge.
• 46 creatures have persist or undying, so they come back after you sacrifice them. A Kitchen Finks pays for emerge twice. See our persist and undying guides.
• 64 cards say “whenever a creature you control dies” or “whenever another creature you control dies”. Each emerge feeds them, just like the sacrifice outlets in an aristocrats deck.
• Stolen creatures. Act of Treason, Zealous Conscripts and Molten Primordial give you an opponent’s creature for a turn. Sacrificing it to emerge means it never goes back.

The fodder in our Herigast deck, and what each one leaves behind:

One line deserves its own sentence: Artisan of Kozilek’s cast trigger returns a creature card from your graveyard to the battlefield, and the creature you just sacrificed is already in the graveyard. Emerge Artisan off a Solemn Simulacrum and Solemn comes straight back, with another land and another card to come when it dies again.

All 15 emerge cards

Sorted by Commander play on EDHREC. “Commander decks” is the number of decks on EDHREC that play the card; prices are the cheapest regular printing on 9 November 2026. 14 of the 15 cost under a dollar.

Three cards take 57% of the 106,852 emerge slots on EDHREC: Crabomination (23,317), Herigast (19,269) and Elder Deep-Fiend (17,839). Two Commander-only cards follow: Cresting Mosasaurus bounces every non-Dinosaur creature when it enters, and Adipose Offspring makes 2/2 tokens equal to the sacrificed creature’s toughness.

The cards worth building around

Elder Deep-Fiend has flash, so you can emerge it during an opponent’s upkeep, after they untap, and tap four of their permanents. Those lands stay tapped for their whole turn. It’s also the classic answer to removal: when an opponent targets one of your creatures, flash in Deep-Fiend and sacrifice the target. Decimator of the Provinces gives your whole team +2/+2 and trample on cast, then hits as a 7/7 with haste. Crabomination sacrifices an artifact (a Treasure, a Clue or a mana rock), then makes an opponent exile three cards and lets you cast one of them free. Herigast is the reason emerge decks exist in Commander at all.

The colourless trick: Zhulodok and Ulalek

12 of the 15 emerge cards are colourless. All twelve Eldrazi have a generic mana cost like {8}; the coloured symbols are only in the emerge cost, which puts them in your colour identity but doesn’t make the card coloured. Two Eldrazi commanders care about exactly that:

• Zhulodok, Void Gorger gives colourless spells with mana value 7 or more that you cast from your hand “cascade, cascade”. Emerge doesn’t lower the mana value (Elder Deep-Fiend stays 8), so an emerged Deep-Fiend still cascades twice into anything costing 7 or less.
• Ulalek, Fused Atrocity lets you pay {C}{C} whenever you cast an Eldrazi spell to copy all spells you control and all other activated and triggered abilities. Emerge an Eldrazi and Ulalek copies its “when you cast” trigger along with the spell.

Herigast is an Eldrazi too, and its own mana cost is {9}: you can hard-cast it with any mana, though its emerge cost needs {R}{R}.

How emerge came to Magic

Emerge debuted in Eldritch Moon in July 2016, the set where Emrakul arrived on Innistrad, and every one of its ten emerge cards is an Eldrazi. Elder Deep-Fiend and Wretched Gryff became Standard staples that autumn in Temur Emerge, which used Kozilek’s Return and cheap creatures that left something behind (Pilgrim’s Eye, Filigree Familiar) as fodder, with Emrakul, the Promised End on top. Emrakul was banned in Standard in January 2017.

The keyword came back in small doses. Adipose Offspring (Doctor Who Commander, 2023) and Cresting Mosasaurus (Jurassic World, 2023) were the first emerge cards that aren’t Eldrazi. Modern Horizons 3 (2024) brought three: Twisted Riddlekeeper, the first emerge cost with {C} in it; Crabomination, the first “emerge from artifact”; and Herigast, the first card that grants emerge.

Best emerge commanders

Herigast is the only commander that gives you emerge; the others either reward the sacrifice or do something with the colourless Eldrazi. If you play the original emerge cards, the colour identity points to Sultai: of the 15, seven need blue, four need green and three need black (Lashweed Lurker needs both blue and green). Muldrotha and Meren also bring the sacrificed creature back, so the same fodder can pay for emerge again next turn.

Is emerge legal in Standard, Modern and Commander?

No emerge card is banned or restricted in any format. Cresting Mosasaurus and Adipose Offspring come from Universes Beyond products (Jurassic World and Doctor Who) that aren’t legal in Pioneer or Modern. Legality checked on Scryfall on 9 November 2026.

Budget Herigast emerge deck ($55)

Herigast is mono-red by colour identity, but most of the deck is colourless: mana rocks, artifact creatures that make mana or draw when they die, and big Eldrazi with cast triggers. The plan is simple. Ramp on turns 1 to 3, put a 3- or 4-drop on the battlefield, then emerge Herigast by sacrificing it: {3}{R}{R} off a 3-drop, {2}{R}{R} off a 4-drop. From then on every creature you cast eats the last one. 36 lands, average mana value 4.36 without lands, 16 creatures with mana value 7 or more. Total $55.12 at the cheapest regular printing of each card. For a public Eldrazi list you can open in the builder, see this Ulalek Eldrazi deck on KrakenTheMeta.

How the deck plays

• Ramp (13 rocks, 3 mana creatures). Sol Ring, Thran Dynamo and Hedron Archive get you to Herigast. The mana creatures double as fodder: tap Palladium Myr for {C}{C}, then sacrifice it.
• Fodder that refunds. Cathodion gives back {C}{C}{C} when it dies, Atsushi leaves three Treasures, and Solemn Simulacrum, Filigree Familiar and Circuit Mender draw a card.
• Payoffs with cast triggers. Artisan of Kozilek brings the fodder back, Desolation Twin makes a 10/10 on cast, Hideous Taskmaster steals a creature from each opponent (which you can then sacrifice to your next emerge spell).
• Anger. Sacrifice it to emerge and, as long as you control a Mountain, every creature you control has haste from the graveyard, Ulamog’s Crusher and Pathrazer included.
• Interaction. Chaos Warp, Blasphemous Act, Vandalblast, Abrade and Lightning Bolt. Blasphemous Act costs {R} once there are eight creatures out.

The ten priciest cards

Those ten are 53% of the deck’s price. Upgrades in order: Ancient Tomb and Eldrazi Temple for speed, Sneak Attack, Wurmcoil Engine as fodder, and It That Betrays, which we cut for price. Run the list through the deck analyzer for its curve and mana base, look up prices in card prices, or browse community decks and the Commander precons for more Eldrazi.

How to beat emerge

Emerge FAQ

What does emerge do in MTG?

It lets you cast a creature by paying its emerge cost and sacrificing a creature. The emerge cost is reduced by the sacrificed creature’s mana value, but only the generic part.

Does emerge reduce coloured mana?

No. If you sacrifice a creature worth more than the generic part, you still pay the coloured symbols. Elder Deep-Fiend always costs at least {U}{U}.

Can I sacrifice a token to emerge?

Yes, but a token that isn’t a copy of a card has mana value 0, so you pay the full emerge cost. That’s still one mana less than the mana cost on most emerge cards.

Does emerge change the creature’s mana value?

No. Decimator of the Provinces is mana value 10 however you cast it. That’s why Zhulodok still gives an emerged Eldrazi cascade.

Do “when you cast” triggers work with emerge?

Yes. Emerge is a way of casting the spell, so cast triggers happen, and they resolve even if the spell is countered.

Can opponents respond to the sacrifice?

No. The sacrifice is part of paying the cost. They can respond to the spell once it’s on the stack, but the creature is already gone.

Can I tap a creature for mana and then sacrifice it to emerge?

Yes. The creature is still on the battlefield while you activate mana abilities during casting, then you sacrifice it.

Does a sacrificed creature’s dies trigger work?

Yes. A sacrificed creature dies, so Solemn Simulacrum draws you a card and Cathodion adds {C}{C}{C}.

What is emerge from artifact?

A variant on Crabomination. You sacrifice an artifact instead of a creature and reduce the cost by the artifact’s mana value. A Treasure or Clue token is worth 0.

What is the best emerge card?

By Commander play, Crabomination (23,317 decks on EDHREC on 9 November 2026), then Herigast at 19,269 and Elder Deep-Fiend at 17,839. For other keywords that change what you pay, see evoke, convoke, warp, delve and affinity, and our annihilator guide for the Eldrazi you’ll be emerging.
