Identity & game plan

  • Win condition: Tribute Summon the 2400-2800 ATK Monarch monsters (Erebus, Ehther, Caius, Thestalos, Kuraz, Zaborg, Eidos) to pressure and remove the opponent's cards.; Recursion of Monarch Spell/Traps from the Graveyard (The Prime Monarch, Pantheism of the Monarchs, Monarchic Perfection) to keep card flow and removal coming.
  • Turn 1 (going first): Search a Monarch Spell/Trap (Tenacity, Masterplan, Revolt) or revive a Tribute enabler (Tessera, Edea, Eidos the Underworld Squire) to reach a Tribute Summon of a 2400/2800 monster, then remove the opponent's key card.
  • Turn 2 (going second): Hold Nibiru (hand trap, usable when the opponent Normal or Special Summons 5 or more monsters) and Monarch removal monsters to answer the opponent's board, then rebuild through searches.
  • Recovery: Recur Monarch Spell/Traps from the Graveyard (The Prime Monarch, Pantheism banish effect, Monarchic Perfection) to search again and draw.
  • After siding: None: the deck runs no side deck, so there is no post-side plan.

Why it scores here

The deck is scored as a system: 21 distinct main-deck cards, 21 searcher-text cards, and roughly a 97% chance of at least one searcher in the opening five cards (Inferred) give it a reliable way to open a Monarch plan, and the three-copy Tribute-summon enablers keep the engine live. Its strength is recursion: Monarch Spell/Traps return from the Graveyard, so one interruption rarely ends the turn, which supports the resilience and grind scores. Its conversion ceiling (2400-3000 ATK Tribute monsters plus several removal effects) is read from card text only, since no recorded boards, guides or usage statistics exist, so the ceiling and median are Inferred. The deck has no side deck and no Extra Deck, which caps the side-adaptability and Extra-efficiency scores, and it has no matchup or tournament data, so the format fit is Provisional and neutral. Popularity or archetype share did not earn any points, and no card scores were averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 68 P(at least one searcher in a 5-card opening hand) ≈ 0.97 from 21 searcher-text cards; the Tribute-enabler copies at 3 each give ≈ 0.31 each per hand (Inferred)
D2 Opening-Hand Quality & Brick Management 62 10 of 21 distinct cards run 3 copies and 8 are singletons; Nibiru x3 is dead without 5+ opposing summons, and several searchers add redundancy (Inferred)
D3 Combo Conversion & Ceiling 60 the Tribute-summon removal monsters (Caius, Zaborg, Thestalos, Ehther) read as a strong ceiling from card text only; no recorded boards exist (Inferred)
D4 Combo Floor & Median Output 52 no recorded boards or power distribution; the Tribute requirement makes the typical early turn fragile (Inferred)
D5 Interruption Resilience & Route Redundancy 68 Monarch Spell/Traps recur from the Graveyard (The Prime Monarch, Pantheism, Monarchic Perfection) and three copies each of the key S/Ts add redundancy (Inferred from card text)
D6 Resource Economy, Recovery & Grind 74 Pantheism draws 2, Prime Monarch shuffles back to draw, and 21 searcher-text cards recycle resources across turns (Inferred from card text)
D7 End-Board & Interaction Quality 66 18 removal-text cards and no negation; Nibiru punishes summon-heavy boards only (Inferred from card text)
D8 Going-Second & Board-Breaking Power 58 going-second hand-trap coverage (Nibiru x3) ≈ 0.36 per six-card hand (Inferred); going-second removal exists but no board data (Inferred)
D9 Offensive Pressure & Closing Power 68 2800 and 3000 ATK Tribute monsters plus Caius's 1000-damage text give closing power on paper; no recorded board or damage data (Inferred from card text)
D10 Main Deck Efficiency & Flexibility 66 23 monsters and 21 spells/traps with 84% exact-name Monarch purity; Nibiru x3 and Tessera x3 are generic-to-archetype, and Foolish Burial Goods is a single copy (Verified legality and composition)
D11 Extra Deck Efficiency & Coverage 45 Extra Deck is empty (0 cards), so there are no Extra slots to use but no Extra flexibility either; scored at 45 (Verified composition, Inferred scoring)
D12 Side Deck Adaptability 20 the side deck is empty, so there is no post-side adaptation at all (Verified)
D13 Matchup Coverage & Format Fit 50 no archetype usage statistics, no tournament link and no dated metagame sample; neutral placeholder (Provisional)
D14 Pilotability & Error Tolerance 60 two- to three-step Tribute and search sequences with several decision points; manageable but not trivial (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.5, Going First ≈ 67, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: no side deck / no post-side plan (-2); engine compactness and coherence (1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.97 · 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

  • Dense searcher and recursion package gives high consistency and card flow (21 searcher-text cards, P(searcher in 5) ≈ 0.97).
  • Monarch Spell/Trap recursion from the Graveyard supports interruption resilience.
  • Tribute-summon monsters at 2400-3000 ATK plus several removal effects give real board pressure and removal density.

Weaknesses

  • No side deck, so no post-side adaptation.
  • No Extra Deck, so the deck has no Extra-based options.
  • No recorded boards, guides or usage statistics, so combo ceiling and floor are text-only inferences.
  • Three Tribute-enabler copies and dead-ish hand trap copies (Nibiru x3) add brick risk.

Critical choke points

  • Tribute Summon requirement: the deck needs a Tribute-able monster on the field for most of its summons.
Priority Remove Add Reason
1 none up to 15 side deck cards A side deck is absent, so there is no post-side adaptation; adding one would be the largest single improvement to D12 and TR (opinion, not verified).
2 one Nibiru copy a second searcher or removal option Nibiru only fires on 5+ opposing summons; a third copy often sits dead in hand (Inferred).

Evidence & confidence

  • Verified: Main deck is 44 cards, within the OCG 40-60 range; Extra and Side are empty.; Foolish Burial Goods runs 1 copy against a Semi-Limited limit of 2; all other cards are Unlimited.; Exact-name Monarch purity 84.1% (37 of 44); 7 generic copies (Nibiru x3, Tessera x3, Foolish Burial Goods x1).
  • Inferred: P(at least one searcher in a 5-card opening hand) ≈ 0.969.; P(at least one 3-copy card in a 5-card opening hand) ≈ 0.31.; Nibiru P(at least one in a 6-card going-second hand) ≈ 0.363.; Engine conversion and resilience scores drawn from card text.
  • Provisional: Meta Power is null and matchup/format fit (D13) is a neutral placeholder without dated metagame data.
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no archetype usage statistics — core/meta-standard comparison unavailable no tournament link — archetype meta-share and per-pilot match record absent no guides attached for the Monarch archetype no side deck and no Extra Deck present in the list no win-rate telemetry exists in YGOVN — going-first/second, matchup, brick and OTK rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
