Constellation in MTG: Rules, History, and Best Cards

Few Magic settings are as enchanting as the Greek mythology-inspired plane of Theros. Watched over by 15 fickle gods, the plane received some notable planeswalker visitors, including Ashiok and Elspeth Tirel. It’s also the home of several interesting, enchantment-themed mechanics.

One of the most pronounced mechanics is constellation, a simple ability that provides tons of value whenever enchantments enter the battlefield. It’s a great mechanic for anybody who loves enchantments and value, but how does it work, and what are the best cards?

Let’s get started!

How Does Constellation Work?

Constellation is an ability that triggers whenever an enchantment enters the battlefield under your control. It’s the equivalent of lands entering and triggering landfall, or creatures entering and triggering alliance, except it’s a triggered ability specific to enchantments. “Enchantmentfall”, if you will.

Enchantments and enchantment creatures with constellation, like Strength from the Fallen or Eidolon of Blossoms, trigger their own constellation ability when they enter play. Non-enchantment creatures, like Triton Waverider, need other enchantments to enter to trigger. Constellation always triggers when a card with the enchantment type comes into play, regardless of any other types it has.

The History of Constellation in MTG

The constellation mechanic debuted in 2014 with Journey into Nyx, the final set of the original Theros block. The mechanic is so heavily linked to the plane of Theros that it almost exclusively appears on card printed in various Theros sets, or on cards from supplementary products that are flavored with Theros in mind. Boon of the Spirit Realm is the only constellation card that isn’t directly tied to Theros in some way.

Is Constellation Optional?

Constellation always puts an ability on the stack when an enchantment enters the battlefield under your control. Most constellation abilities are non-optional, although there are a few with a “may” clause that lets you decline to use the ability as it resolves.

Do Auras Without Targets Trigger Constellation?

An aura that enters the battlefield will trigger constellation even if it has no targets. That’s most likely to happen with blink effects that return an aura to the battlefield without a legal target. In those cases, the aura still enters, then goes to the graveyard as a statebased action if it’s not enchanting anything. Constellation effects will still see that an aura enchantment entered and trigger accordingly.

What if You Kill the Creature in Response to the Constellation Trigger?

Once the constellation trigger is on the stack, it resolves regardless of whether the creature that created the trigger is still in play. The only exception would be if the creature created a constellation trigger that targeted itself; for example, if Pious Wayfarer targeted itself for +1/+1 and then died, the ability would fizzle because it no longer had a target. Targetless constellation triggers still resolve, even if you removed the enchantment or the creature in response.

What if You Kill the Creature in Response to the Enchantment?

If you kill the creature with constellation in response to the enchantment being cast, the creature won’t trigger. The permanent with constellation needs to be on the battlefield at the same time the enchantment comes into play to “see” it enter. If the creature dies first and goes to the graveyard or any zone other than the battlefield, it won’t see the enchantment enter the battlefield, and it won’t trigger.

Constellation vs. Eerie

Eerie was introduced in Duskmourn: House of Horror as a riff on constellation, with the only difference being that eerie also triggers when you fully unlock a room enchantment. Otherwise it works exactly like constellation, triggering when an enchantment enters the battlefield.

Best Constellation Cards

#6. Archon of Sun’s Grace

Archon of Sun's Grace is a premier constellation token maker, and a totally fine midrange creature on its own. One of very, very few must-haves for anyone trying to make a Thurid, Mare of Destiny pegasus deck work.

#5. Boon of the Spirit Realm

Boon of the Spirit Realm is a mega-anthem for enchantment decks. It triggers itself on entering, so it’s at minimum a static +1/+1 to the board, but it can go crazy when you untap and drop a couple more enchantments. Not too hard to get this up to +5/+5 or greater.

#4. Calix, Guided by Fate

Calix, Guided by Fate had a stint as a top tier threat in Standard, and now lives comfortably in Selesnya enchantment Commander decks. Constellation for counters makes it harder to block, and every hit from Calix lets you copy an enchantment, which means even more +1/+1 counters. It’s a snowballing threat that you’ll see a lot in Sythis, Harvest's Hand decks.

#3. Doomwake Giant

Doomwake Giant plays board control very well, and you don’t even have to be all in on enchantments. It’s also asymmetrical, so you don’t have to shape the sizing of your creatures around it. This is the first card I’m reaching for in any enchantment deck running black.

#2. Nylea’s Colossus

Nylea's Colossus hits hard. Rather, it’s more accurate to say it makes something else hit hard, since you’re likely targeting another creature when this enters. Untap with the giant and you can start doubling its power instead, very easily making it a 24/24 or bigger in a dedicated enchantment deck.

#1. Eidolon of Blossoms + Setessan Champion

In Commander, Eidolon of Blossoms and Setessan Champion are must-have constellation cards for any deck with a strong enchantment theme. These are two particularly powerful enchantresses; Eidolon replaces itself, and the Champion becomes a serious threat if left unchecked. Since these both draw on ETB instead of on-cast like traditional enchantresses, you can also do all sorts of flicker tricks to maximize your card draw.

Decklist: Anikthea, Hand of Erebos Constellation in EDH

Anikthea, Hand of Erebos is a fantastic commander to helm a deck built around constellation. It’s an enchantment itself and it’s in Abzan colors, the perfect home for enchantress decks in general. Anikthea’s powerful “reanimation” ability does a great job getting multiple constellation triggers a turn.

Our best constellation cards are the enchantresses, like Sythis, Harvest's Hand and Argothian Enchantress, which provide the baseline card draw you’ll need for the deck to function. A deck with this much card draw needs plenty of mana, so Nessian Wanderer and Composer of Spring pull a lot of weight by providing easy access to extra lands.

Constellation effects also help this deck control the board. Doomwake Giant makes it impossible for your opponent to keep tokens or small-value creatures in play, and you get enough constellation triggers that this can become a full board wipe. Thoughtrender Lamia ignores the board and goes straight for the hand, attacking another valuable resource. Nylea's Colossus provides a constellation wincon; it only takes three constellation triggers to give Anikthea 32 power, so you can take an opponent out from nowhere with commander damage.

This deck draws tons of cards so it’s always casting spells, but getting to put enchantments into play just by attacking with Anikthea does so much to get multiple constellation triggers reliably. In turn, these constellation triggers give the deck incredible value on top of the board presence Anikthea creates just by existing.

Wrap Up

Constellation is one of my personal favorite mechanics, as a player who loves both value and enchantments. It’s flavorful and fun, and a mechanic I hope we get to see more of going forward. It offers interesting design space, especially since it’s harder to use than similar effects like landfall. A resurgence in constellation could even signal a new enchantment-themed plane. Imagine how interesting it would be to find a Theros god traveling through the Omenpaths.
