Radiant Typhoon Deck #774726 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±6 · Confidence: Medium)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck boss monsters (Chaos Angel, Desirae, Super Starslayer TY-PHON, Albion, Constellar Ptolemy M7) reached through Fiendsmith and Bystial tributes and summons; Fiendsmith Engraver and Radiant Typhoon Eldam/Swen tempo into Link and Fusion follow-ups
• Turn 1 (going first): Search or draw an engine starter (Radiant Typhoon Swen/Eldam or Fiendsmith Engraver), use Mystical Space Typhoon or Crossout Designator to clear a backrow threat, then summon a Bystial or Fiendsmith boss
• Turn 2 (going second): Use Ash Blossom, Effect Veiler, Ghost Ogre or Maxx C to break the opponent's first summon chain, then convert a surviving Bystial or Fiendsmith monster into a Link or Fusion boss
• Recovery: Fiendsmith's Requiem and Lacrima recursion from the GY, Bystial Saronir and Druiswurm banishing LIGHT or DARK monsters from either GY, and Radiant Typhoon Chant or Vision search
• After siding: Not applicable: Master Duel has no side deck and the list runs 0 side cards, so there is no post-side adjustment

Why it scores here

The deck reliably opens a live starter most of the time, with about a 0.89 chance of at least one searcher in an opening hand and a 0.91 chance of at least one card from the archetype-grouped core, though this is a Main Deck hypergeometric estimate rather than observed play. Its strongest system feature is interaction: 11 hand traps plus Maxx C, Crossout Designator and Mystical Space Typhoon give layered answers to a summon chain or a backrow threat, and this is the main reason it scores above its engine quality. Conversion is credible but unproven because no recorded boards exist, so the ceiling rests on Extra Deck bosses such as Chaos Angel, Desirae and Super Starslayer, and the median is discounted for the spread across several archetype engines. The list spans Fiendsmith, Bystial, Radiant Typhoon, Branded, Constellar and Ecclesia pieces, with only 12.5 percent exact-name purity and only 9 of 25 usage-core cards present, so the engine conflicts and missing Radiant Typhoon staples (Krosea, Fonix, extra Mystical Space Typhoons) cap the score. Popularity and the guide's praise did not earn points, and the score was built from the system dimensions rather than by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 57, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: engine_conflicts (-3); missing_core_staples (-2); banlist_exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Layered interaction: 11 hand traps plus Maxx C, Crossout Designator and Mystical Space Typhoon
• Strong going-second hand-trap coverage (about 0.87 in six-card hands)
• High-ceiling Extra Deck bosses with multiple summon routes
• Recursion from the GY through Requiem, Lacrima and Bystial banishers

Weaknesses

• Multi-archetype engine spread with only 12.5 percent exact-name purity
• Only 9 of 25 usage-core cards present; Radiant Typhoon engine is thin on staples
• Extra Deck slots are all singles across several unrelated engines, so reliable access is limited
• No recorded boards, so the conversion and median claims rest on text inference

Critical choke points

• Mystical Space Typhoon at 1 copy is the main engine enabler for Radiant Typhoon and the usual conversion starter
• Radiant Typhoon Swen and Eldam (2 copies each) gate the Radiant Typhoon line; without them the Radiant Typhoon route is dead
• Single-copy Limited cards (Maxx C, Vision, Magnamhut) cannot be replaced if they are dead or lost

Recommended changes

Evidence & confidence

• Verified: Legality: 41 Main and 15 Extra, within the Master Duel size rules, with Limited and Semi-Limited copy counts respected; Card text for hand traps, Mystical Space Typhoon, Crossout Designator and the Extra Deck bosses; Usage core: 9 of 25 core cards present, 36 percent; Archetype purity: 12.5 percent exact-name purity, with 49 off-archetype copies
• Inferred: Starter access ≈ 0.89 from hypergeometric odds; Ceiling and median rely on text inference, because no recorded boards exist; Engine conflicts and brick risk from composition; Going-second strength from hand-trap coverage
• Provisional: Meta Power is null because no dated metagame sample exists; Matchup fit and side-deck adaptability, since Master Duel has no side deck
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry; going-first, going-second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null, so the deck is identified only by its archetype and id
