Duskmourn: House of Horror
Miracle Worker
Surveil into miracle triggers is powerful but timing-dependent, the most demanding of the four. Out of the box, before any upgrades. How we rate precons
Buy Miracle Worker on TCGplayer →Quick verdict
Miracle Worker is a deck about controlling the top of your library so that an expensive enchantment is the first card you draw each turn, at a large discount. Aminatou, Veil Piercer makes that happen every upkeep with a surveil, and the deck backs it up with plenty of cheap card selection. What holds it back is a mana base full of tapped lands in three colors, several cards that do little for the miracle plan, and too few enchantments that are truly worth cheating out.
TurnZero HQ rates Miracle Worker a 4 out of 5 on difficulty and a 4 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 Miracle Worker decklist page, and every other precon we cover is on the precon directory.
How the precon plays
Aminatou, Veil Piercer surveils 2 at the beginning of your upkeep, which lets you look at your top two cards and put either into the graveyard. It also gives every enchantment card in your hand miracle, with a miracle cost equal to its mana cost reduced by four generic mana. Miracle lets you cast a card for that cost when you draw it, as long as it is the first card you drew that turn.
Put together, the upkeep surveil sets up your draw step. If an enchantment is on top, you draw it and cast it cheaply. One with the Multiverse goes from eight mana to four, and Extravagant Replication costs two. Cards that put things back on top, like Brainstorm , Ponder , Portent , Telling Time , Diabolic Vision and Brainstone , let you stack an enchantment for the next draw. Moon-Blessed Cleric searches for an enchantment and puts it right on top.
The deck also plays real miracles. Terminus is a one-mana board wipe when miracled, Entreat the Angels makes a pile of 4/4 fliers, and Redress Fate returns every artifact and enchantment from your graveyard. Sigil of the Empty Throne and Mesa Enchantress pay you for each enchantment you cast.
What works out of the box
Aminatou, Veil Piercer ↗
Surveils 2 every upkeep and gives enchantments in hand miracle at four generic mana less. It sets up and pays off the same draw step.
Sigil of the Empty Throne ↗
Makes a 4/4 flying Angel whenever you cast an enchantment. Cast for its miracle cost, it is only two mana.
One with the Multiverse ↗
Lets you play cards from the top of your library and cast one spell free each turn. A miracle makes it four mana instead of eight.
Moon-Blessed Cleric ↗
Searches for an enchantment and puts it on top of your library, so your next draw step is a miracle you picked.
Terminus ↗
Puts every creature on the bottom of its owner's library for one white mana when miracled. It answers indestructible creatures too.
Mesa Enchantress ↗
Draws a card whenever you cast an enchantment, which keeps the hand full while the deck plays one enchantment after another.
What needs improvement
The mana base is the biggest problem. Three-color decks need untapped duals, and this one runs Temples, Thriving lands, bounce lands, Arcane Sanctum and Bojuka Bog , all of which enter tapped. On a turn where you want to miracle an enchantment, a tapped land can leave you one mana short.
Several cards don't help the plan. Verge Rangers and Monologue Tax are not about enchantments or the top of the library, Aminatou's Augury is an eight-mana sorcery that Aminatou can't discount, and Spirit-Sister's Call and Life Insurance are slow. The deck also has few enchantments with a mana cost high enough to make Aminatou's four-mana discount count in full.
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. Add enchantments worth a miracle
Aminatou removes up to four generic mana, so an enchantment costing five or more is where the discount matters most. The deck has only a few of those.
What to look for Enchantments with at least four generic mana in their cost and an effect that changes the board, plus creatures that reward each enchantment entering.
Cut, for example
Verge Rangers A 3/3 first striker that plays lands from the top only when an opponent has more lands. It does nothing with enchantments or miracles.
Monologue Tax Makes Treasure only when an opponent casts two spells in a turn. It is slow ramp in a deck that ramps with discounts instead.
Add, for example
Overwhelming Splendor ↗
Eight mana normally, four as a miracle: one opponent's creatures lose all abilities and become 1/1s, and that player can't activate most abilities.
Starfield of Nyx ↗
Returns an enchantment card from your graveyard to the battlefield each upkeep. As a miracle it costs a single white mana.
Archon of Sun's Grace ↗
A 3/4 lifelink flier that makes a 2/2 flying Pegasus whenever an enchantment enters under your control.
2. Draw cards on more turns
Miracle only checks the first card you draw in a turn. Draws on opponents' turns give you more of those first draws, and each one can turn an enchantment you stacked on top into a miracle.
What to look for Instants and permanents that draw a card at the start of your turn or on an opponent's turn, ideally cheap enough to hold up with the rest of your mana.
Cut, for example
Spirit-Sister's Call Five mana to swap a permanent for a matching one in your graveyard at each end step. It needs the right cards in the yard and does nothing the turn it lands.
Aminatou's Augury An eight-mana sorcery, which Aminatou's discount doesn't apply to. In most games it sits in hand.
Add, for example
Phyrexian Arena ↗
Draws a card each upkeep for 1 life. Order Aminatou's surveil first and the Arena draw becomes the first card you draw that turn, so the card you set up can be miracled.
Faerie Mastermind ↗
A two-mana flash flier that draws you a card whenever an opponent draws their second card in a turn. Those draws happen on opponents' turns, where they count as your first.
Opt ↗
One mana at instant speed to scry 1 and draw. Cast it at the end of an opponent's turn and the card it draws can be a miracle.
3. Swap slow cards for cheap answers
The deck's interaction leans on sorcery-speed enchantments and miracle wipes. A couple of cheap instants handle a threat on the turn it appears.
What to look for Instants costing three mana or less that exile a permanent or counter a spell.
Cut, for example
Timely Ward An Aura that gives your commander indestructible. It does nothing against exile or bounce, and removing the commander also takes the Aura with it.
Life Insurance Five mana for extort and Treasure when creatures die. It is slow in a deck that wants to spend its mana on enchantments.
4. Replace tapped lands with untapped duals
A three-color deck with this many tapped lands often has the wrong mana on the turn a miracle shows up. Untapped duals fix that.
What to look for Two-color lands in any pair of white, blue and black that can enter untapped, or fetch lands that find a basic.
Cut, for example
Thriving Heath Enters tapped and makes only two colors. The deck has many tapped lands already.
Thriving Moor The same issue: a tapped land that covers only two of your three colors.
Bojuka Bog Enters tapped and makes only black. Its graveyard hate is narrow, and it is easy to hold back for the right moment.
Win conditions
The deck wins with value it didn't have to pay full price for. Sigil of the Empty Throne and Entreat the Angels build a flying army, One with the Multiverse lets you play a free spell every turn, and Overwhelming Splendor shuts down the opponent most likely to stop you. Terminus and Time Wipe reset the table if you fall behind, and your enchantment-based threats survive a creature wipe.
Who should buy this precon
A demanding deck for an experienced player who enjoys planning a turn ahead. Every upkeep you decide what to keep on top, you need to know which draws count as the first in a turn, and you have to remember the miracle trigger before the card goes into your hand. That makes it rewarding to master but easy to misplay at first, so it suits someone comfortable with Commander already rather than a newer player.
