Legality
Main 40 / Extra 9 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Tribute Summon Monarch monsters to control board with removal and hand traps; Grind via Horus/King's Sarcophagus recursion and spell recycling
- Turn 1 (going first): Set Monarch spells/traps, search with Tenacity/Masterplan, tribute summon Ehther/Erebus for removal and card advantage
- Turn 2 (going second): Use hand traps (Ash, Veiler, Impermanence) and Strike/Kuraz to break board then tribute summon
- Recovery: Recycle Monarch spells via Pantheism/Prime Monarch, special summon from GY with King's Sarcophagus
- After siding: None (no side deck)
Why it scores here
This deck is a Monarch/Horus tribute-summon midrange pile with a non-functional Shaddoll/Fossil extra deck; it was scored on system consistency and grind, not on individual card strength. The main deck shows high searcher density (P≥1 searcher ≈0.97) and redundant tribute lines, giving moderate opening reliability, but the extra deck is almost entirely dead because no fusion or synchro enablers exist in the main deck. Median output is a single Monarch tribute with removal and a hand trap, while ceiling is limited by the lack of extra-deck conversion. No tournament data or parsed combos were available, so meta power is provisional and consistency claims are inferred from hypergeometric estimates. Popularity of archetype core cards did not earn points; the score reflects engine cohesion and brick risk only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | Searcher-text group 19 copies yields P(≥1 in 5)=0.969; King's Sarcophagus 3 copies P=0.338 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 60 | Only 1 Shaddoll Schism brick without Shaddoll monsters; Horus monsters need King's Sarcophagus; copy histogram shows 13 singles (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No parsed combos; ceiling inferred as tribute summon + removal ~55 (Inferred) |
| D4 | Combo Floor & Median Output | 50 | No combo floor data; median inferred as single Monarch play ~50 (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Multiple Monarch monsters and spells provide redundant tribute routes but vulnerable to squire removal (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 65 | Pantheism/Prime Monarch recycle spells; King's Sarcophagus sends to GY for value (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | 7 hand-trap copies and multiple on-summon removal effects; no persistent negate board (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 55 | Going-second hand-trap P(≥1 in 6)=0.711; board breakers via Strike/Kuraz but need tribute setup (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Monarch beaters 2400-2800 ATK; Domain boost conditional; no reachable 5000 Dragon (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 65 | 40-card main compact but includes dead Shaddoll trap and mismatched Horus (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 10 | Extra deck 9 cards but no Fossil Fusion/Polymerization/Tuner-Dino support, making most unusable (Verified/Inferred) |
| D12 | Side Deck Adaptability | 0 | Side deck count 0, no post-side plan (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament context; format fit provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Complex tribute summon conditions and extra-deck lock traps raise misplay risk (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 62, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Unusable extra deck (-3); No side deck (-2); Shaddoll sub-engine absent monsters (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)
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
- High searcher density and redundant Monarch tribute lines
- Good hand trap count for interaction
Weaknesses
- Extra deck almost entirely unusable
- No side deck
- Shaddoll sub-engine incomplete (no monsters)
Critical choke points
- Reliance on Tribute Summon mechanics vulnerable to summon negation
- King's Sarcophagus needed for Horus plays
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Shaddoll Schism | Monarch extender or staple trap | Shaddoll Schism bricks without Shaddoll monsters; replace with usable card |
| 2 | Fossil Machine Skull Wagon (extra) | Playable Extra Deck monster reachable (e.g., Rank 5 Xyz) | No Fossil Fusion in deck makes Skull Wagon dead |
Evidence & confidence
- Verified: Legality status Legal; Side count 0; Extra deck breakdown 7 fusion 1 xyz 1 synchro
- Inferred: Consistency from hypergeometric; Brick risk from missing sub-engine; Extra deck dead weight from card text
- Provisional: Matchup format fit; Meta power
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
