Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 44 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Quick-Play Spell chains that Special Summon Radiant Typhoon monsters (Krosea, Varuroon, Fonix) and then attack with 2900-3000 ATK boss monsters (Fonix, Shiina, Predaplant Triphyoverutum, Secreterion Dragon); Link and Fusion boards built from Radiant Typhoon Eldam, Swen and Varuroon the Marine Eidolon, backed by Mystical Space Typhoon recursion
• Turn 1 (going first): Open Radiant Typhoon Eldam or Swen to search a Radiant Typhoon card, use Mystical Space Typhoon or a Quick-Play Spell to bring out a Radiant Typhoon monster, and hold Ash Blossom or Ghost Belle for the opponent's first activation
• Turn 2 (going second): Use Ash Blossom, Ghost Belle, Droll & Lock Bird and Forbidden Droplet to slow the opponent's first board, then Quick-Play Spell into Krosea or Varuroon and pivot into a boss monster
• Recovery: Recycle Mystical Space Typhoon and Radiant Typhoon Chant or Ascendance from the GY, and use Mulcharmy Fuwalos or Purulia as a hand refill when the board is empty
• After siding: No side deck in Master Duel (side_count 0); post-side is not applicable

Why it scores here

The deck reliably opens a Radiant Typhoon line: the 18-copy archetype core has about a 94% chance of at least one card in a 5-card opening hand, and the 16 searcher cards have about a 91% chance, so the engine is usually live by turn 1 to 2 (Inferred). Its disruption is layered: five hand traps, Forbidden Droplet, Crossout Designator and Varuroon's negation give it several ways to interrupt the opponent's first activation, and Quick-Play Spell chains let it recover after a single answer. Conversion depends on Quick-Play Spell timing and on boss monsters at 2900 to 3000 ATK, but no recorded boards exist, so the ceiling and median stay text-only estimates and are scored conservatively. The score comes from consistency, interaction density and closing power assessed on the whole system. Archetype popularity and the single guide did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 65.5, Going First ≈ 70, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Extra Deck dilution (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*65.5 + 0.20*62 = 64.8, then -3 modifiers = 61.8, rounded to 62)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is about 94% likely to be present in an opening 5-card hand
• Five hand traps plus Forbidden Droplet, Crossout Designator and Varuroon's negation give layered early and mid-turn interaction
• Several recovery lines (Eldam, Swen, Chant, Ascendance, Manifestation) let the deck continue after one answer
• Strong closing bodies at 2900 to 3000 ATK (Fonix, Shiina, Predaplant Triphyoverutum, Secreterion Dragon)

Weaknesses

• No recorded boards, so the combo ceiling and median are unmeasured
• Only 35.6% of main cards are exact-archetype; Mulcharmy, Forbidden and Branded splashes reduce coherence
• Extra Deck is crowded with off-plan fusions and synchros, which reduces coherence and costs flexibility
• The engine depends on Quick-Play Spell timing, which raises the pilot skill floor

Critical choke points

• Mystical Space Typhoon in the GY is the key enabler for several effects; losing it to a single removal line weakens recovery
• Only three Limited cards are run at 1 copy, so losing one of them leaves no backup

Evidence & confidence

• Verified: Legal in master-duel: 44 main, 15 extra, 0 side; no violations; Eight restricted cards are all within their legal copy limits; Archetype usage stats list 14 rows with 10 of 14 core cards present; Archetype core group: 18 copies in deck
• Observed: No recorded combo boards exist for this deck
• Inferred: Hypergeometric opening-hand probabilities for the engine, searchers and hand traps; Engine resilience, interaction density and boss closing power from card text; Going-first and going-second estimates
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit; Side deck adaptability (not applicable in Master Duel)
• 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 and brick/starter rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied
