Frog Deck #759700 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±8 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Spright and Link/Xyz beatdown: Gigantic Spright (x2) and Spright Elf/Sprind (x2 each) convert the Spright engine into board presence and attack; Divine Arsenal AA-ZEUS is listed but has no Level 12 monsters to use as material (Inferred from its text and the deck's level spread), so it is effectively a dead Extra slot
• Turn 1 (going first): Open Spright Starter or Spright Jet/Blue as the starter, search a Spright Spell/Trap, and protect the first line with Ash Blossom, Infinite Impermanence and Dominus Impulse (Inferred from card text)
• Turn 2 (going second): Hold Ash Blossom, Maxx C, Infinite Impermanence and Dominus Impulse to stop the opponent's first summon, then rebuild through Spright Carrot or Spright Red negates (Inferred)
• Recovery: Recover from the graveyard through Frog or Nimble recursion and Spright Sprind and Elf Link re-summons; the recursion chain is text-only and unverified (Inferred)
• After siding: Not applicable: Master Duel is single-game ranked with no sideboard (side count 0 by format)

Why it scores here

This list is illegal in Master Duel because it runs Called by the Grave, which is Forbidden, so the score is a theoretical structural read only and the final number is capped low. Its real engine is the Spright package (about 21 copies by the archetype spread), not the Frog archetype named on the deck, since only 4 copies carry the exact Frog name. The Spright starters reach a live board about a third of the time in the opening five (P(at least one Spright Starter in 5) is about 0.34), and searchers push that to roughly 0.58. Interaction is the strongest part of the system, with seven hand traps and about fifteen negation-text cards, which keeps the deck resilient after a first interruption. The score comes from consistency, interaction and resilience on the system, not from the Frog name, not from averaging the cards' individual power, and not from any win-rate data, since none exists here.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 53, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure_forbidden (-12). Final formula: Illegal list: 0.80*Structural(51) + 0.20*TournamentReliability(50) = 51, then a -12 banlist-exposure modifier, giving 39 as a theoretical structural-only score (Meta provisional, not a legal-deck score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 hand-trap and negate suite (7 hand traps, about 15 negation-text cards) gives strong early interaction
• Spright package shares one Level 2 body pool, so most copies can start the engine and feed link/Xyz material

Weaknesses

• Illegal: Called by the Grave is Forbidden in Master Duel
• Archetype label says Frog but only 4 copies are Frog; 51 copies are off-name and dilute the engine
• Divine Arsenal AA-ZEUS has no Level 12 material, so it occupies a dead Extra slot

Critical choke points

• Spright Starter (3 copies) is the single most-used starter; a 34% opening-five hit rate makes a soft mulligan decision on every hand

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 sizes are within master-duel size rules; Called by the Grave is Forbidden, 1 copy run, making the list illegal; Engine card counts from the archetype spread (Spright about 21, exact Frog 4)
• Inferred: Starter and searcher hit rates from hypergeometric draws; Hand-trap and negation density as an interaction read; Going-first and going-second plans from card text; Divine Arsenal being dead without Level 12 material
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament data); Side-deck adaptability (no sideboard in Master Duel)
• 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 for going-first/second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null, so the archetype label is the only name available
