Legality

Main 55 / Extra 0 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Tribute Summon a 2800-ATK Monarch (Mobius, Caius, Zaborg, Ehther, Erebus) and attack, with on-summon removal clearing blockers.; Eidos the Underworld Monarch (2400 ATK) and recursion-driven grind through Monarch Spell/Traps in the Graveyard.
• Turn 1 (going first): Opening-hand searcher (Edea, Tessera, Mithra, or a Monarch Spell/Trap) reaches a Tribute Summoned monster, then a Monarch Tribute Summon removes the opposing blocker or threat.
• Turn 2 (going second): Six-card hand with a Monarch starter, Tribute Summon a Monarch to remove the established board, then rebuild from Graveyard recursion; Majesty's Fiend is a conflict here.
• Recovery: Pantheism, Masterplan and Domain search or banish-recur Monarch Spell/Traps, while Prime Monarch and Monarchic Perfection recycle the Graveyard.
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan.

Why it scores here

The deck reliably opens a functional engine: 23 of 55 Main Deck cards carry searcher text, and the hypergeometric estimate gives P(at least one searcher in a 5-card opening hand) of about 0.94, so the Monarch line is almost always reachable on turn 1. Conversion comes from Tribute Summoning 2800-ATK Monarchs whose on-summon effects remove or destroy opposing cards, and from recursion through Pantheism, Masterplan, Prime Monarch and Monarchic Perfection that keeps the deck playing after a disruption. The main weaknesses are the Tribute Summon gate (a Tribute Summoned monster is needed before most Monarchs), the absence of hand traps and a Side Deck, and three copies of Majesty's Fiend, which shuts off the deck's own monster effects. The score is built from consistency, median output and interaction on the system; Monarch's popularity did not add points, no card scores were averaged, and no meta data was available, so Meta Power stays provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 65, Going First ≈ 67, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Majesty's Fiend engine conflict (-2); Winged Dragon of Ra Sphere Mode dead weight (-2); No-Extra-Deck synergy (1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural drops D13 and renormalises the Midrange weights over 95): 0.80*65 + 0.20*58 - 3 = 61

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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 density (23 cards) makes the engine almost always accessible on turn 1.
• On-summon removal from Monarch Tribute Summons, plus GY recursion, gives a grind-capable midrange shell.
• Zero hand traps and no Side Deck, but the removal-on-summon package carries most interaction.

Weaknesses

• No hand traps, no negates and no Side Deck, so the deck has little answer to a fast or disruptive opponent.
• The Tribute Summon gate needs a Tribute Summoned monster, which slows the Monarch line when the starter is absent.
• Majesty's Fiend suppresses monster effects for both players, including this deck's own Monarchs.
• Sphere Mode (3 copies) and 15 off-archetype copies dilute the engine.

Critical choke points

• Reaching a Tribute Summoned monster before the Monarch Tribute Summon; Tessera, Edea and Mithra are the bridge cards.
• Opponent's monster-effect negation or a board that survives the Tribute Summon removal.

Recommended changes

Evidence & confidence

• Verified: Legal: 55 Main Deck cards, 0 Extra, 0 Side; within the TCG size rules.; Restricted cards are within legal copies (Foolish Burial 1 Limited, Reinforcement of the Army 1 Limited, Foolish Burial Goods 1 Semi-Limited).; Archetype purity: 40 exact Monarch copies, 15 off-archetype (72.7%).; 0 hand traps; 3 floodgate copies (Majesty's Fiend); 20 removal-text cards; 23 searcher-text cards.
• Inferred: P(>=1 searcher in 5-card opening hand) ~0.94; 0.25 per 3-copy card going first.; Tribute-summon gate and recursion give the engine redundancy and grind (D1, D5, D6).; Majesty's Fiend conflicts with the deck's own monster effects.
• Provisional: Meta Power and D13 matchup fit: no dated metagame sample or tournament link.
• Data gaps: No combos supplied; combo ceiling, median and floor are text-only inference. No tournament link; archetype meta-share and per-pilot record are absent. No win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown. usage_statistics for archetype 451 list 25 core cards, of which 23 are off-archetype (Clown Crew, Mulcharmy, Tri-Brigade and others) and only Zaborg matches this deck. The table looks mis-keyed or generic and was not used to score. No Side Deck, so post-side and D12 are scored from composition only. Meta Power is provisional without a dated metagame sample.
