Starfield of Nyx: Triggers, Probabilities, and Practical Play

If you love the intersection of math and magic, Starfield of Nyx is a delightful puzzle box 🧙‍♂️. This white enchantment from Commander Masters asks you to count souls as you count enchantments. With a mana cost of 4W and a tempting two-part text, it invites you to plan for the long game as you balance recursion and a snowballing board presence. The card is a mythic reprint in the Commander Masters set, illustrated by Tyler Jacobson, and it arrives with the kind of design that rewards careful counting and deliberate build decisions 💎⚔️.

Oracle text: At the beginning of your upkeep, you may return target enchantment card from your graveyard to the battlefield. As long as you control five or more enchantments, each other non-Aura enchantment you control is a creature in addition to its other types and has base power and base toughness each equal to its mana value.

In practical terms, Starfield of Nyx gives you a two-pronged tempo: a resurrection engine and a board-wide buff that scales with your enchantment count. The first ability—reviving an enchantment from your graveyard at upkeep—creates a recurring value engine. The second ability—the five-enchantment threshold that turns many of your non-Aura enchants into creature powerhouses—offers a faith check on your middle-to-late-game development. Building around these triggers invites a blend of recursion spell-slinging, protection for your key enchantments, and a careful curation of non-Aura enchantments that survive the wraths and removal common in Commander formats. In a deck that leans into enchantments, Nyx becomes less about a single blow and more about a sustained, radiant chorus of effects 🎨🎲.

Two triggers, two kinds of probability

Let’s parse the two mechanics with an eye toward probability and practical play. The math is not a dull spectator sport—it's the difference between knowing when your Beacon of Tomorrows will actually hit versus hoping for the best 🔥.

  • The upkeep recursion: At the start of your upkeep, you may return target enchantment card from your graveyard to the battlefield. The odds of this triggering meaningfully depend on two factors: (a) how many enchantments you have in your graveyard that are legally retrievable, and (b) how many targets you actually want to return. If your graveyard routinely fills with enchantments—reanimator style—the chance of pulling a useful enchantment back increases. If you’re light on graveyard targets, you’ll still trigger the ability, but you’ll likely pass or fetch something less impactful. In play terms, plan to maximize value when you have at least one strong enchantment in graveyard that can immediately influence the board or tempo 🧙‍♂️.
  • The five-enchantments buff: The other half of Nyx’s pact requires five or more enchantments under your control. That threshold transforms every non-Aura enchantment you control into a creature and grants it base power/toughness equal to its mana value, turning a tidy board into a real threat. The probability of reaching this five-enchantment board state hinges on deck density and draw pace. A deck that heavily leans into enchantments—even if not all are “combat-ready”—improves your odds, as does a smooth mix of acceleration and ways to keep enchantments from leaving the battlefield. Remember: Auras don’t count toward the five-enchantment requirement, so your build should favor non-Aura enchants to maximize the payoff 🧩.

Estimating odds in practice: a method you can actually use

To estimate how often you’ll hit the five-enchantment threshold by a given point in the game, you can use a simple hypergeometric model. Think of your deck as N cards long, with E of those being enchantments. As you draw t cards by a certain turn, the number of enchantments you’ve drawn X follows a hypergeometric distribution. The probability that you’ve drawn at least five enchantments is:

P(X ≥ 5) = sum from k=5 to min(E, t) of [ C(E, k) * C(N − E, t − k) / C(N, t) ]

In standard MTG terms, N is usually 60 for a typical constructed deck, though EDH players often play with 100-card decks and scale accordingly. E is the total enchantments in your deck, and t is the number of cards you’ve drawn by the target turn. Plugging in different densities (for example, a deck with one-third enchantments) and different draw counts (turn 4–7) gives you a spectrum of outcomes. In practice, the five-enchantment buff tends to be a more reliable late-game payoff than an early-game slam, so you’ll see higher probability as you push into later turns and accumulate enchantments on the battlefield. The math rewards patient planning and thoughtful card selection 🧠💡.

Similarly, the probability of having a valid target in your graveyard for the upkeep recursion can be framed with a similar idea: if your graveyard holds G enchantments that are eligible targets, the chance you have at least one viable target when Nyx triggers is a direct function of how often those enchantments are sent to the graveyard and how many you’re playing. The more you run, the more “fuel” you have for returns, and that fuel often complements the five-enchantment goal—two paths toward victory running in parallel ⚔️.

Practical deck-building tips to tilt the odds in your favor

  • Density matters: Favor enchantments that help you ramp or draw, as well as those that provide value on death or enter-the-battlefield effects. Non-Aura enchants that offer immediate utility or game-ending phrases are sweet spots for Nyx’s buff to shine 💎.
  • Protect your engines: Since the first ability depends on graveyard targets, include targeted recursion, inequality-proof removal, and ways to protect your enchantments from mass removal or graveyard hate. A safe Nyx stride often depends on keeping your engine alive through the mid-game)
  • Aura vs. non-Aura distinction: Remember that only non-Aura enchantments count toward the five-enchantment threshold. If your deck leans heavily on Auras, you’ll want a careful plan to ensure a sufficient number of “creature-enchantment” threats appear on the battlefield to leverage the buff.
  • Graveyard setup: Plan for a pipeline where you can reliably return an enchantment to the battlefield when the upkeep arrives. That often means sequencing your draws and activations to keep a meaningful target ready when Nyx’s upkeep comes around 🧭.
  • EDH pacing: In 100-card Commander decks, you’ll generally see a slower cadence, but the payoff can be bigger when you stabilize into a board full of enchanted creatures and a revived toolbox on the battlefield. The EDHREC data point for Starfield of Nyx indicates its resonance in the format—as a mythic card with a distinct, player-friendly payoff—but your mileage will vary by your table’s removal suite and ramp density 🎲.

Design, flavor, and value in the multiverse

Starfield of Nyx stands out for marrying a resurrection engine with a scalable minotaur-sized board buff. The artwork and the sense of a starry, divine field align with Nyx’s mythic aura—the plane where gods, mortals, and enchantments collide under the night-sky canopy. The card’s reprint status in Commander Masters makes it a familiar luxury for players who chase the nostalgia of strong enchantment themes while appreciating modern design cues. The mythic rarity and its price tag in the market speak to its collector appeal as much as to its strategic potential in a grown-up, enchantment-centric build 🔮.

For players who want to experiment beyond the usual suspects and lean into a true “enchantment tribe” vibe, Starfield of Nyx is a natural pick. It invites you to explore the tension between tempo and value, to anticipate how often you’ll recur a key enchantment, and to enjoy the moment when your board finally gleams with five or more shimmering non-Aura artifacts that are creatures and ready to swing ⚔️💎.
