Magic's constellation explained: rulings, Theros roots, top 6 cards
A Draftsim explainer covers how constellation works, its rulings, its 2014 debut in Journey into Nyx, and a ranking of six cards for Commander enchantment decks.
Constellation, the Magic: The Gathering ability tied to Theros, is the subject of a new Draftsim explainer. It covers the rules, the history, and Draftsim's ranking of six constellation cards, plus a sample Commander decklist built around Anikthea, Hand of Erebos. The material is reported by a community site, not announced by Wizards of the Coast.
How constellation works
Any time an enchantment enters the battlefield under your control, constellation fires. What matters is the enchantment type, regardless of whatever other types the card has. Enchantment creatures that carry constellation, such as Strength from the Fallen or Eidolon of Blossoms, set off their own ability as they arrive. A non-enchantment creature such as Triton Waverider needs other enchantments to arrive.
The majority of constellation abilities are mandatory, but some include a "may" clause, so you can choose to skip the effect as the ability resolves.
Rulings that come up in play
An Aura entering the battlefield triggers constellation even with no legal target, for example when it is blinked back. If it ends up enchanting nothing, a state-based action sends it to the graveyard.
Once a trigger is on the stack, it resolves even if the creature that created it has left the battlefield. The exception is a trigger targeting the creature itself, which fizzles if that creature dies, as with Pious Wayfarer targeting itself for +1/+1.
Timing matters too. Should the creature be killed in response to the enchantment spell, no trigger happens, since the creature has to be on the battlefield at the moment the enchantment enters.
Theros history and the Eerie variant
The ability first appeared in 2014 in Journey into Nyx, which closed out the original Theros block. Nearly every constellation card was printed in Theros sets or in supplementary products given a Theros flavor. Boon of the Spirit Realm is the only constellation card not directly tied to Theros. Theros is a Greek mythology-inspired plane watched over by 15 gods, visited by planeswalkers including Ashiok and Elspeth Tirel.
Eerie, introduced in Duskmourn: House of Horror, is a variant of constellation. Besides enchantments entering, it fires when a Room enchantment becomes fully unlocked, and in other respects it plays like constellation.
The ranked list
The constellation cards on Draftsim's list are Archon of Sun's Grace, Boon of the Spirit Realm, Captivating Unicorn, Eidolon of Astral Winds, Doomwake Giant, Nylea's Colossus, Setessan Champion, Calix, Guided by Fate, Underworld Coinsmith, and Eutropia the Twice-Favored. Here is the top six:
- #6 Archon of Sun's Grace: a constellation token maker and a key card for a Thurid, Mare of Destiny pegasus deck.
- #5 Boon of the Spirit Realm: an anthem that triggers itself on entering for at least +1/+1 to the board, and can reach +5/+5 or more with more enchantments.
- #4 Calix, Guided by Fate: once a top-tier Standard threat, it has since settled into Selesnya enchantment Commander decks. Its constellation hands out counters, and when it connects you can copy an enchantment.
- #3 Doomwake Giant: asymmetrical board control and the first pick for black enchantment decks.
- #2 Nylea's Colossus: each constellation trigger can double a creature's power, producing a 24/24 or bigger in a dedicated enchantment deck.
- #1 Eidolon of Blossoms plus Setessan Champion: must-haves for Commander enchantment decks, both drawing on ETB rather than on cast, which enables flicker tricks.
What is still unknown
No new constellation cards or Theros products are announced, and no release dates or prices are given.
What it means for players
- Check timing: the creature must be on the battlefield when the enchantment enters.
- Auras with no legal target still trigger constellation.
- Because they draw on ETB instead of on cast, Eidolon of Blossoms and Setessan Champion open the door to flicker tricks.
- Anikthea, Hand of Erebos has a sample constellation Commander list in the explainer.
