Forbidden Deck #525905 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Tempo, Pendulum/Xyz engine
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Majespecter Pendulum Summon (scale 2 + scale 5) into a Level 3/4 engine that feeds Extra Deck Xyz and Link monsters, with Hraesvelgr, Tenyi and Malevolent Sin as closers; Xyz and Link pressure from Number 75, Blackship of Corn, Photon Papilloperative and Cross-Sheep once the board is established
• Turn 1 (going first): Open a pendulum monster (Raccoon, Crow, Toad or Fox) and a second pendulum monster of the other scale, Pendulum Summon, search a Majespecter card, then go to Extra Deck Xyz or Link monsters while holding Ash Blossom and Tempest
• Turn 2 (going second): Use Ash Blossom and Majespecter Tornado or Cyclone to interrupt the opponent's first summon, then rebuild through the pendulum searchers and Majesty's Pegasus or Porcupine
• Recovery: Majespecter Supercell returns five Majespecter cards from the GY to draw 1, and the searchers (Raccoon, Crow, Fox, Cat) rebuild the pendulum pair from hand or deck
• After siding: No side deck (0 cards). Master Duel gives no post-side plan, so the deck relies entirely on its main-deck adaptability

Why it scores here

The deck is scored as a system: 14 pendulum monsters with 10 searcher or search-text cards give a high chance of at least one pendulum starter in hand (about 0.90, Inferred), and the real bottleneck is the scale-2 plus scale-5 pair, which is about 0.37 going first and 0.47 going second (Inferred, from hypergeometric estimates). Ash Blossom, Majespecter Tempest, Tornado and Cyclone give the deck real interruption and end-board interaction, which is what lifts D5 and D7. Its Extra Deck of 15 cards mixes Xyz, Link and Pendulum options, but most of them do not share a common engine, so D11 stays moderate. The score does not come from Forbidden being a popular label, from the usage statistics (whose core cards are almost entirely absent from this list), or from averaging individual card strength. With no recorded combos, no side deck and no meta sample, combo, side and matchup dimensions are Inferred or Provisional and the uncertainty band is kept at plus or minus 6.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Engine compactness (2); Scale-pair choke point (-2). Final formula: No reliable metagame: Final = 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*62 + 0.20*60 = 61.6 → 62; modifiers net 0

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ 0.37 · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Pendulum starters with redundant searchers: 14 pendulum monsters, 10 searcher or search-text cards
• Strong interaction suite: Ash Blossom ×3, Majespecter Tempest ×3, Tornado and Cyclone
• Compact, coherent main deck (27 of 40 Majespecter)
• Recursion through Majespecter Supercell and self-recovery through Majesty's Pegasus

Weaknesses

• Scale-pair requirement (scale 2 and scale 5) lowers consistency, especially going first
• Extra Deck of 15 with weak shared engine (mostly generic Xyz and Link)
• No side deck and no recorded combos to validate the conversion
• Possible brick risk from non-engine cards (Snake-Eye, Chalice, Storm, Supercell)

Critical choke points

• Having both a scale-2 and a scale-5 pendulum monster in the opening hand

Recommended changes

Evidence & confidence

• Verified: Legal status: 40 main, 15 extra, 0 side, all cards Unlimited (legality block); Majespecter count 27 of 40 (composition block); Hypergeometric draw odds (probabilities block)
• Inferred: Pendulum starter and scale-pair estimates (≈0.90 and ≈0.37/0.47); Going-second interaction estimate; Engine coherence and closer assessment from card text
• Provisional: Meta Power and D13 matchup fit (no dated sample or tournament link); D12 side deck adaptability (no side deck in Master Duel)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry for going-first, going-second or matchups Usage statistics do not match this list: the core cards (Yummy, Lollipo, Snatchy and others) are 1 of 25 present, so the statistics describe a different build and were not used to score Archetype label 'Forbidden' does not match the actual Majespecter engine Meta Power is Provisional until a dated metagame sample is supplied
