How to play

Inspired by Inkborn Heroes' "Sapphire/Steel Detectives Budget" on Dreamborn.

The premium deck in the lineup, and the most tournament-capable. Sapphire/Steel ramp midrange with Detective tribal payoffs. Use Sail the Azurite Sea on turn 2 to put an extra card into your inkwell that turn (effectively jumping you one ink ahead of schedule), then deploy your 4 and 5 ink Detectives a full turn early, quest every turn, and close with Judy Hopps - Lead Detective enabling your Detective squad.

The ramp turn is everything. Sail the Azurite Sea on turn 2 puts you at 4 inks ready on turn 3, which lets Judy Hopps - Uncovering Clues or Nick Wilde - Persistent Investigator land a full turn before opponents can answer them. Miss the ramp turn and you are one turn behind your win condition for the entire game. That compounds into 6 to 8 missing lore over 4 or 5 turns.

Quest first, challenge second. Your Detectives are questers, not combat pieces. Let Steel removal (Strength of a Raging Fire, The Terror That Flaps in the Night) handle opposing threats while your Detectives quest uncontested. The pivot turn: turn 6 when Judy Hopps - Lead Detective lands. Her LATERAL THINKING ability gives all your Detective characters Alert (they can challenge characters with Evasive) AND Resist +2 (damage dealt to them is reduced by 2) during your turn. Combat becomes profitable once Judy is on board.

The Detective math advantage. Judy Hopps - Uncovering Clues quests for 1 lore AND looks at the top 3 of your deck for another Detective on every quest. Nick Wilde - Persistent Investigator quests for 2 lore AND draws a card whenever one of your Detective characters banishes another character in a challenge. The combination is a self-fueling engine: tutor for Detectives with Judy, challenge with them under Lead Detective's Alert buff, draw a card per Detective banish, repeat.

Two key combos to remember:

  • Darkwing Duck - Cool Under Pressure (7 cost, 6 strength, 8 willpower, 2 lore) has EVILDOERS BEWARE! He can challenge READY Villain characters (he doesn't have to wait for them to be exerted). The Thunderquack (3 cost Steel item) has VIGILANTE JUSTICE that classifies all opposing characters as Villains. So with The Thunderquack on board, Darkwing Duck - Cool Under Pressure can challenge ANY ready opposing character.
  • The Terror That Flaps in the Night (2 cost Steel action) deals 2 damage to chosen opposing character normally, OR 3 damage instead if you have any Darkwing Duck character in play. The deck runs 12 Darkwing Duck cards total (across three versions), so the 3-damage clause is almost always live. Treat it as a 3-damage burn spell, not a 2-damage one.

Matchup role. Faster deck against aggressive opponents (Steel removal clears their low-willpower flood faster than they can rebuild); also faster against grind decks (your ramp advantage is a full turn, so your threats land before their answers). Let It Go and Princess Power invert that: their tall-willpower bodies outlast yours, so Judy Hopps - Lead Detective's challenge-as-Evasive grant is your only clean path through.

Lore math. 14 cards quest for 1 to 2 lore. A realistic mid-game turn 5 has 3 Detectives questing = 6+ lore per turn. Target 20 lore by turn 7 or 8.

Mulligan

Single-pattern keep, no exceptions. Sail the Azurite Sea, a 2-cost Detective character, and an inkable card. Always.

Conditional keep: Doc - Bold Knight if in opener. 2 ink, 1 strength, 3 willpower, 1 lore, Steel uninkable. NOT a Detective (he is a Knight/Seven Dwarfs subtype), but a card-advantage engine: his DRASTIC MEASURES on entry lets you discard your hand to draw 2 cards. Useful late game when your hand is bricky; not a turn 1 or 2 play.

Ship hands without ramp. Without Sail the Azurite Sea on turn 2, the deck stalls a full turn behind. Your win-condition Detectives (5 cost) land turn 5 instead of turn 4. The compounding deficit is rarely recoverable.

Ship hands without 1-cost or 2-cost characters. Your early game exists to stall until your ramp lands and your mid-curve Detectives arrive. A hand starting at turn 4 has already ceded the board.

Ideal turn 1 through 3 line. Turn 1: 1-cost character quests. Turn 2: cast Sail the Azurite Sea, then ready all inks (4 inks ready by start of turn 3 thanks to the extra ink). Turn 3: play Nick Wilde - Persistent Investigator OR Judy Hopps - Uncovering Clues one full turn early. By turn 4 you have a 2-lore Detective questing that your opponent expected to see at turn 5.

Key cards

Early board (play on-curve, quest the next turn):

  • Darkwing Duck - Crime Fighter and Nick Wilde - Sly Fox Sleuth: 1 ink, 2 strength, 2 willpower, 1 lore, Steel inkable. Both vanilla 1-cost Detectives (no abilities). Play turn 1; quest from turn 2. They exist to generate 1 lore each turn and survive until your threats land. Don't hold them; deploy them early.
  • Darkwing Duck - Drake Mallard: 2 ink, 4 strength, 1 willpower, 1 lore, Sapphire inkable. Aggressive 4-strength 2-cost Detective with Ward (opponents can't choose this character except to challenge — so opposing action cards and triggered abilities can't target him). The Ward keyword protects him from removal actions like Let It Go, Strength of a Raging Fire (when used as a debuff target), and similar. His 4 strength trades up into most 2-cost opposing characters.
  • Doc - Bold Knight: 2 ink, 1 strength, 3 willpower, 1 lore, Steel uninkable. NOT a Detective (Knight/Seven Dwarfs subtype). DRASTIC MEASURES on entry: you may discard your hand to draw 2 cards. A hand-reset for mid-game when you have inflated bricky cards in hand. Don't play him turn 2 if your hand is good; save him for a late-game reset.

Ramp (the most important play every game):

  • Sail the Azurite Sea: 2 ink Sapphire action. This turn, you may put an additional card from your hand into your inkwell facedown. Then draw a card. Commit your entire turn 2 to ramping; don't play a 2-cost character instead. The advantage from being at 4 inks ready on turn 3 is worth more than a single 2-ink character questing one turn earlier. This is the one play where you sacrifice a quest for a bigger long-game advantage.

Mid-game threats (all land 1 turn early via ramp):

  • Mickey Mouse - Detective: 3 ink, 1 strength, 3 willpower, 1 lore, Sapphire uninkable. GET A CLUE on entry: you may put the top card of your deck into your inkwell facedown and exerted. A one-shot ramp on entry that effectively pays for itself. Plus he is a Detective for tribal-trigger purposes.
  • Judy Hopps - Uncovering Clues: 4 ink, 3 strength, 3 willpower, 1 lore, Sapphire inkable. THOROUGH INVESTIGATION: when played AND whenever she quests, look at the top 3 cards of your deck. You may reveal a Detective character card and put it into your hand; put the rest on the bottom of your deck in any order. A self-fueling Detective tutor. Primary turn 3 play via ramp; quests turn 4.
  • Nick Wilde - Persistent Investigator: 5 ink, 5 strength, 4 willpower, 2 lore, Steel uninkable. Shift 3 (you may pay 3 ink to play this on top of another Nick Wilde). CASE CLOSED: during your turn, whenever one of your Detective characters banishes another character in a challenge, draw a card. Workhorse 2-lore body in the mid-game AND the draw engine that fuels your hand once you start challenging.
  • Donald Duck - Along for the Ride: 5 ink, 4 strength, 6 willpower, 2 lore, Steel inkable. NOT a Detective (Hero subtype only). COMIN' THROUGH! on entry: you may banish chosen item. Removes opposing items like Fishbone Quill, Dinglehopper, or Queen's Sensor Core on his entry. Also a tall-willpower 2-lore body. Without Sail the Azurite Sea, you wait until turn 5 to play him; with ramp he lands turn 4.

Closers:

  • Judy Hopps - Lead Detective: 6 ink, 6 strength, 4 willpower, 2 lore, Sapphire inkable. Shift 4 (you may pay 4 ink to play her on top of another Judy Hopps). LATERAL THINKING: during your turn, your Detective characters gain Alert AND Resist +2. Alert means they can challenge characters that have Evasive. Resist +2 means damage dealt to them is reduced by 2. The Detective squad enabler. Deploy turn 6 (or Shift-cost turn 5 onto Judy Hopps - Uncovering Clues) to unlock challenging across your whole Detective board.
  • Darkwing Duck - Cool Under Pressure: 7 ink, 6 strength, 8 willpower, 2 lore, Steel inkable. Shift 5 (you may pay 5 ink to play this on top of another Darkwing Duck). EVILDOERS BEWARE!: this character can challenge READY Villain characters (he doesn't have to wait for them to exert). TAKE THAT!: during your turn, whenever an item is banished (yours or opposing), you may pay 1 ink to deal 2 damage to chosen character. He is NOT Evasive on his own. Combine with The Thunderquack (which classifies all opposing characters as Villains) for the EVILDOERS BEWARE! ability to fire against any opposing board.

Interaction (use precisely):

  • The Terror That Flaps in the Night: 2 ink Steel action. Deal 2 damage to chosen opposing character. IF you have any Darkwing Duck character in play, deal 3 damage instead. The deck runs 12 Darkwing Duck cards (4 Crime Fighter, 4 Drake Mallard, 4 Cool Under Pressure), so the 3-damage clause is almost always live. Treat it as a 3-damage burn spell baseline. Clears 1, 2, and 3 willpower opposing characters from play.
  • Strength of a Raging Fire: 3 ink Steel song. Deal damage equal to the number of characters you have in play to chosen character. Sung free by any 3+ cost character. Premium removal that scales with your board. Save for opposing characters you cannot remove via combat (tall willpower or Evasive bodies that would otherwise quest unchallenged).
  • Let It Go: 5 ink Sapphire song. Put chosen character into their player's inkwell facedown and exerted. Sing for free with Nick Wilde - Persistent Investigator (5 cost) or Donald Duck - Along for the Ride (5 cost). Permanent single-target soft removal without losing your own character in a combat trade. Don't pay the full 5 ink; always sing it.
  • The Thunderquack: 3 ink Steel item. VIGILANTE JUSTICE: all opposing characters gain the Villain classification while this item is in play. Makes Darkwing Duck - Cool Under Pressure's EVILDOERS BEWARE! usable against any opposing character. LAY OF THE LAND: exert this item, if a character was banished in a challenge this turn, gain 1 lore. Converts Detective combat banishes into bonus lore.
  • Inkrunner: 2 ink Sapphire item, inkable. PREFLIGHT CHECK on entry: draw a card. So the item effectively pays for itself: 2 ink in, 1 card drawn out. READY TO RIDE: exert this item and pay 1 ink, chosen character gains Alert this turn (they can challenge characters with Evasive). A repeatable Alert grant on a character of your choice, so Detectives can challenge Evasive characters even before Judy Hopps - Lead Detective lands.

Matchups

vs. Amethyst/Sapphire Evasive (Unfavorable): Watch for: Dumbo - Ninth Wonder of the Universe, Hades - Looking for a Deal The deck you will run into most often. Their Evasive characters bypass your Detective blockers entirely. Judy Hopps - Lead Detective's LATERAL THINKING grant only lets YOUR Detectives challenge characters with Evasive on YOUR turn; it doesn't let your Detectives block their Evasive characters. Strength of a Raging Fire is your one clean removal for Dumbo - Ninth Wonder of the Universe; save a copy specifically for him. Inkrunner's READY TO RIDE can grant Alert to a Detective on a turn you need to attack one of their Evasive characters before Judy Hopps - Lead Detective lands. Win window is turn 6 or 7 with Judy on board, before their engine compounds past 15 lore.

vs. Amber/Emerald Aggro (Favorable): Watch for: Tramp - Street-Smart Dog, Grandmother Willow - Ancient Advisor Steel removal eats their wide flood. The Terror That Flaps in the Night deals 3 damage (with any Darkwing Duck in play) and one-shot removes their 1 to 3 willpower bodies. Strength of a Raging Fire scales with your Detective board and clears 3 to 4 of theirs by turn 5. Don't let them establish 4 or more bodies before you remove them. Width compounds, but you have the removal to stay ahead.

vs. Amethyst/Steel Challengers (Even): Watch for: Beast - Snowfield Troublemaker, Strength of a Raging Fire Both decks grind midrange. The opposing Challenger +2 buffs let their characters trade cleanly into your 3 to 4 willpower Detectives. But your turn 2 ramp (cast Sail the Azurite Sea on turn 2) plays threats a full turn earlier than they expect. Sequence ramp first, then threats, so Judy Hopps - Lead Detective lands turn 5 with The Thunderquack giving you +1 lore per Detective combat banish. That is the swing engine.

vs. Amber/Steel Steelsong (Even): Watch for: He Hurled His Thunderbolt, Angel - Experiment 624 Both midrange. Doc - Bold Knight runs in their list and yours. The matchup turns on whether yours stays alive longer (he is a 1-strength, 3-willpower body either way). He Hurled His Thunderbolt deals 4 damage and clears 2 of your Detectives per cast; push toward Judy Hopps - Lead Detective plus LATERAL THINKING Resist +2 before they assemble their full song chain (Resist +2 reduces Thunderbolt from 4 to 2 damage on your Detectives).

vs. Ruby/Sapphire Control (Unfavorable): Watch for: Maui - Hero to All, A Pirate's Life Their Maui hard-removes your closers; their Sapphire draw out-paces your Detective tutoring. Sing Let It Go off Nick Wilde - Persistent Investigator to tuck Maui - Hero to All before he challenges. That's the only swing turn that matters. Past turn 8 they grind you out.

Tune It

Already at the competitive ceiling for a budget Detective build. The deck challenges meta decks consistently when the ramp turn lands.

Upgrade option: 2 or 3 copies of Lexington - Small in Stature (3 ink, 4 strength, 4 willpower, 1 lore, Steel inkable). Alert keyword native (can challenge characters with Evasive). STONE BY DAY drawback: he can't ready when you have 3 or more cards in your hand, so play him on turns when you have a low hand. Note: he is NOT a Detective (Storyborn/Ally/Gargoyle), so Judy Hopps - Lead Detective's LATERAL THINKING does NOT buff him. His value is being an additional Alert-keyword body before turn 6 (when Judy lands), so you can attack opposing Evasive characters earlier.

Ink-color note on tech swaps. Stay within Sapphire and Steel only (the 2-ink rule prevents adding Emerald or Amethyst cards). All Cheshire Cat variants are Emerald or Amethyst, so no Cheshire Cat fits this deck. For damage-redistribution effects in Sapphire/Steel specifically, the available options are sparser than in Emerald.

Outlook. LOW Core rotation risk. The Detective synergy core (Darkwing Duck / Nick Wilde / Judy Hopps) is anchored in Set 10 and Set 11, which survives the next Core rotation when Set 13 lands. Cards to watch for rotation: Sail the Azurite Sea (verify a Set 9 or later printing exists), and Inkrunner (check its set). Business rule for restocks: this is the one current meta deck you can build inventory depth in without rotation fear. The Infinity format also never rotates, so this list is Infinity-legal forever as a fallback.
