Generaider Deck #774356 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Level 9 Generaider bosses (Vala, Loptr, Harr, Hela, Mardel, Utgarda, Nidhogg) convert into Xyz pressure via Laevatein, Jormungandr and the Number Xyz monsters.; Galaxy-Eyes Tachyon Primal and Number C107 as high-ATK finishers when the Level 9 line is established.
• Turn 1 (going first): Open with Generaider Boss Stage, Vala or Loptr plus a Dododo/Gogogo/Zubaba-type starter, then build a Level 9 Xyz line through the Extra Deck.
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird and Maxx C to answer the opponent's first summons or draws, then stabilise with Harr, Nidhogg or Utgarda removal and negation.
• Recovery: Ash Blossom (x3) and the Generaider GY-revival text on Vala and Dodododwarf Gogogoglove provide repeat access to Level 9 bodies after disruption.
• After siding: Not applicable: the deck carries no Side Deck (0 cards) and Master Duel is not played best-of-3 with side cards, so D12 is neutral and no post-side plan is scored.

Why it scores here

The deck reliably opens a functional starter: the searcher text (11 copies) gives about 82% odds of at least one searcher in a 5-card opening hand, and Generaider Boss Stage and the Vala/Loptr starters each have about 34% odds in hand (Inferred). Its ceiling comes from a Level 9 Generaider boss line feeding a 15-card Xyz Extra Deck (Laevatein, Jormungandr, Number C107, Enterblathnir), which can produce boards of 2500 to 4500 ATK, but no recorded boards exist, so the median and floor are inferred rather than observed. Interaction is the deck's clearest strength: six hand traps (Ash Blossom x3, Droll & Lock Bird x2, Maxx C), plus removal and negation text on Harr, Nidhogg, Utgarda and Unbreakable Xyz Barrier, gives it layered answers for both turns. Scoring is on the system: consistency, interaction and Level 9 closing power were weighed together, and the deck's popularity (100% core inclusion across the Generaider archetype stats) earned no points by itself, and card scores were not averaged. Structural power is held down by the 32.7% exact-archetype purity (Dododo, Gagaga, Galaxy, Utopia and Mathmech copies), 16 singleton slots, and an absent side deck, and the score is capped by the missing meta and tournament data.

Dimension scores

How the score was computed

Strategy profile: 0.7 * Midrange + 0.3 * Combo. Structural ≈ 59.5, Going First ≈ 64, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine conflicts / sub-archetype spread (-3); Banlist exposure (Limited card) (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample): 0.80*59.5 + 0.20*52 - 4 = 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Searcher density (11 cards) gives high odds of a functional opening hand.
• Six hand traps with three Ash Blossom copies provide redundant interruption on both turns.
• Level 9 bosses and a 15-card Xyz Extra Deck give high closing power.
• Layered removal and negation text covers boards and summons.

Weaknesses

• Low exact-archetype purity (32.7%) and 16 singleton slots reduce engine coherence.
• No recorded boards, so the floor and median are unverified.
• No Side Deck, though Master Duel is single-game, so no sideboard flexibility exists.
• Multi-step Xyz and Level 9 decisions increase pilot error risk.

Critical choke points

• The Level 9 boss line depends on several Generaider Level 9 monsters being in hand or GY; a missing boss stalls the Xyz chain.
• Interaction relies on 6 hand traps; a hand with none of them is exposed on going-second turns (about 35% of six-card hands with no hand trap).

Recommended changes

Evidence & confidence

• Verified: Legal status: 40 Main, 15 Extra, 0 Side within Master Duel size rules.; Maxx C at 1 copy (Limited, legal 1); Droll & Lock Bird at 2 copies (Semi-Limited, legal 2).; Card text excerpts for Vala, Loptr, Harr, Nidhogg, Utgarda, Ash Blossom and Unbreakable Xyz Barrier.; Archetype usage stats show the Generaider core is standard across the archetype.
• Inferred: Opening-hand odds for searchers and starters (hypergeometric).; Hand-trap coverage on the going-second turn (6-card hand 0.65).; Interaction and closing-power quality from card text.; Level 9 boss line as the primary plan.
• Provisional: Meta Power and matchup fit (no dated metagame sample).; Median and floor (no recorded boards).
• Data gaps: No combos supplied (total_combos 0): floor, median and ceiling are text-only inference. No tournament link: archetype meta share and per-pilot match record absent. No win-rate telemetry exists for this deck: matchup and turn-order signals are Inferred. Meta Power is provisional without a dated metagame sample. Inconsistent usage_statistics: Jormungandr, Number F0: Utopic Future, Number F0: Utopic Draco Future, Number F0: Utopic Future Zexal, Number 102, Primathmech Alembertian, Starring Knight, Galaxy Photon Dragon, Gagagaga Girl, Number C107 and Phantom Fortress Enterblathnir are marked in_this_deck:false, yet they appear with copies in the cards list. The cards list was used as the source of truth; core_present_pct (56) is therefore unreliable. archetype_core_group probability (0.987) is a proxy and was not used for scoring.
