Identity & game plan

  • Win condition: Tribute-summon chain into 2800 ATK Monarch boss monsters (Erebus, Ehther, Thestalos, Caius), with Domain of the True Monarchs adding ATK to attackers; Monarch spell/trap recursion (The Prime Monarch, Return of the Monarchs, Pantheism) to rebuild the chain after a removal or negation
  • Turn 1 (going first): Open with a level 5+ or level 1-2 starter (Kuraz, Eidos, Edea), Tribute a monster to bring out a Monarch boss, then search a second Monarch through Pantheism, Tenacity or Return
  • Turn 2 (going second): Use Solemn Warning (2000 LP) to protect the first Tribute Summon and Majesty's Fiend to stop monster effects on the opponent's board, then rebuild the boss through the Monarch graveyard recursion
  • Recovery: Monarch spells and traps in the graveyard are shuffled back and drawn (The Prime Monarch, Return), and Pantheism banish-search returns a Monarch to the hand
  • After siding: None: the deck has no Side Deck, so no post-side plan is available (data gap)

Why it scores here

The score comes from the system: a 40-card Monarch list whose searchers (15 cards, P(at least one in a 5-card opener) about 0.92) give reasonable access to the Tribute-summon chain, and whose eight Level 8 and 2800 ATK bosses (Erebus x3, Ehther x3, Thestalos, Caius) provide a real ceiling. The chain itself is fragile: 18 monsters against 22 spells and traps means a fair share of hands are non-functional, and the first Tribute Summon needs a level 5+ or Tribute-capable starter, so the opener is a single point of failure. Recursion through the Monarch graveyard (The Prime Monarch, Return, Pantheism) and Solemn Warning give some resilience. The deck has no Side Deck, so it earns almost nothing for adaptability, and the going-second plan relies on a single negation and one floodgate. Popularity was not used: the usage statistics attached to this archetype list cards that are not in the Monarch build (Clown Crew, Ghost Belle, Mulcharmy), so no core-card credit was given. No card scores were averaged.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one of 3 copies of a specific starter in a 5-card hand) = 0.3376; P(at least one of 15 searchers in a 5-card hand) = 0.92; the first Tribute Summon needs a level 5+ or Tribute-capable starter (Inferred)
D2 Opening-Hand Quality & Brick Management 45 18 monsters and 22 spells/traps (45% monster ratio); several Monarch spells and traps are dead without a Monarch in the graveyard; full-brick rate not computed (Inferred)
D3 Combo Conversion & Ceiling 70 Ceiling from text: 2800 ATK Tribute bosses, a 2-copy Prime Monarch loop, and Caius banish removal; no recorded boards exist to confirm it (Inferred)
D4 Combo Floor & Median Output 50 No recorded combos, so the median is unknown and placed at the midpoint without evidence (Provisional)
D5 Interruption Resilience & Route Redundancy 60 Three graveyard recursion routes (The Prime Monarch, Return of the Monarchs, Pantheism banish) and Solemn Warning for one-card disruption (Inferred)
D6 Resource Economy, Recovery & Grind 62 Draw and search text (Pantheism draw 2, Eidos, Edea, Ehther) and recursion give a moderate economy; no resource signature data (Inferred)
D7 End-Board & Interaction Quality 58 Removal text in 17 cards (Caius, Kuraz, Ehther) and Solemn Warning as the only negation; no hand traps; the interaction is mostly single-use (Inferred)
D8 Going-Second & Board-Breaking Power 45 Going-second relies on Solemn Warning and Majesty's Fiend (floodgate); there is no hand-trap density and no recorded going-second split (Inferred)
D9 Offensive Pressure & Closing Power 65 Eight 2800 ATK monsters and Domain of the True Monarchs (+800 ATK on Tribute attackers); the closing text is strong but unverified in play (Inferred)
D10 Main Deck Efficiency & Flexibility 60 Compact 40-card main with no Extra Deck and no Side Deck; 6 of 40 copies (15%) are off-archetype (Solemn Warning, Majesty's Fiend, Foolish Burial, One for One, Reinforcement, Allure) (Verified)
D11 Extra Deck Efficiency & Coverage 50 Zero Extra Deck cards; no Extra Deck coverage is used, and Monarch cards such as Stormforth, Return and March explicitly block Extra Deck Special Summons (Verified)
D12 Side Deck Adaptability 5 No Side Deck exists, so no post-side plan is possible (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament link and no dated meta sample; archetype share is unavailable (Provisional)
D14 Pilotability & Error Tolerance 40 Multi-step Tribute chains with several decision points, plus graveyard recursion and Monarch-name restrictions (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 56.6, Going First ≈ 58, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: No Side Deck (-3); Tribute-summon choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*56.6 + 0.20*48 - 5 = 49.9, rounded to 50 (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Searchers (15) give a high chance of finding a Monarch in any opener
  • Eight 2800 ATK bosses on a compact 40-card list
  • Three independent graveyard recursion routes
  • Single-card disruption (Solemn Warning, Caius) plus a floodgate (Majesty's Fiend)

Weaknesses

  • 18 monsters versus 22 spells and traps; monster-light openers are common
  • No Side Deck, so no post-side adaptation
  • The Tribute-summon engine has one starter bottleneck
  • Off-archetype copies (Solemn Warning, Majesty's Fiend, Foolish Burial, One for One, Reinforcement, Allure) dilute the engine

Critical choke points

  • The first Tribute Summon requires a Tribute Summoned monster already on the field
  • Solemn Warning is the only negation; the opponent can stop the chain with one unanswered removal or negation
Priority Remove Add Reason
1 One for One A level 5+ monster or an extra Monarch starter One for One costs a card and does not feed the Tribute chain; a second starter improves the monster count and the first Tribute Summon
2 Allure of Darkness A Side Deck of 15 cards The deck has no Side Deck, so it has no post-side adaptation; a side is the largest gain for best-of-3 play

Evidence & confidence

  • Verified: Legal: 40 Main, 0 Extra, 0 Side; 4 Limited cards at 1 copy each and Solemn Warning at 1 copy (Semi-Limited, legal max 2); 34 Monarch-named copies and 6 off-archetype copies (85% exact-name purity); 18 monsters, 22 spells/traps, 8 cards at 2800 ATK, no Extra Deck, no Side Deck
  • Inferred: Opening-hand probabilities for each card and for the searcher group; The Tribute-summon chain is fragile at the opener; Ceiling and resilience scores come from card text, not recorded boards
  • Provisional: Meta power and archetype matchup fit (no dated meta sample); Median output (no recorded boards)
  • Data gaps: No recorded combos: floor, median and ceiling are text-only inference The usage statistics attached to this archetype list cards outside the Monarch build (Clown Crew, Ghost Belle, Mulcharmy, Zaborg and others), so they were not used as a core-card baseline; the archetype link appears to be wrong No Side Deck: post-side plan and D12 cannot be evaluated beyond the absence No tournament link and no win-rate telemetry: matchup, going-first/second split and brick rates are unknown Deck title is null
