Vaylantz Deck #712677 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±8 · Confidence: Medium)

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

Legality

Main 51 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Pendulum Summon engine into Link/Extra Deck boards with interaction and removal; combo into field control.; Going-second disruption via hand traps and forced board breaks.
• Turn 1 (going first): Establish Pendulum Scales (odd/even), Link into GranSolfachord Coolia or end-board negation, float hand traps.
• Turn 2 (going second): Hand traps (Ash, Herald, Maxx C, PSY-Gamma, Nibiru) into forced Pendulum Summons and board piercing.
• Recovery: Recursion via field spell effects, GY searchable Pendulum Monsters, and hand-trap redundancy.
• After siding: Limited by 0 side deck; cannot adapt post-match. Structural vulnerability in best-of-3.

Why it scores here

This deck is ILLEGAL in Master Duel due to 3 copies of Herald of Orange Light (banlist limit: 1 copy). Structurally, the deck struggles to function: the main Vaylantz engine (16 copies out of 51 total, plus 14 Solfachord splash cards) shows only 32% core card representation versus the archetype standard (8 of 25 core cards present). Consistency P(at least one Vaylantz/Solfachord starter) ≈ 84%, but opening hands routinely conflict (multiple Pendulum starters with no extenders, hand traps clogging slots). The combo output is median-tier: no scored boards exist in evidence, so ceiling and floor are inferred from card text and linearity; expected boards end with 2–3 interaction points (GranSolfachord Coolia negate + a Field Spell lockdown). Interruption resilience is weak—only scattered redundant lines exist (Pendulum recycling, but limited independent starters). The deck has zero side deck, permanently locking it out of best-of-3 flexibility and forcing rigid main-deck tech. Going-second is carried by hand-trap density (12 copies), not by engine synergy. Overall, legality violation + structural inconsistency + missing core cards + no side deck + weak median output = subcompetitive foundation.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 50, Going First ≈ 54, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Illegality penalty (-12); Missing side deck (-5); Low core card representation (-3). Final formula: Illegal deck: 0.80*Structural(50) + 0.20*TournamentReliability(38) + Illegality modifier(−12) = 40 − 8 = 32. (Meta provisional, side deck missing.)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.84 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Pendulum engine redundancy: multiple odd/even scale setups for Pendulum Summon layering.
• Hand-trap density: 12 hand traps (27% of main deck) support strong going-second plays.
• Interaction breadth: 20 cards with negation text, 17 with removal, spread across Pendulum and Link monsters.
• Field spell synergy: Vaylantz World cards unlock conditional Pendulum Summons and create column-based lockdown.
• Extra deck link coverage: 13 Link monsters with diverse utilities (draw, search, removal, negate).

Weaknesses

• ILLEGAL in Master Duel: Herald of Orange Light 3x exceeds copy limit (1); deck cannot be used in official format.
• Low core card count: only 32% of archetype standard (8/25); missing key tutors (Infinite Impermanence, Dominus Impulse, Knightmare Gryphon).
• High brick rate: 51-card main with 31 distincts creates conflicting hands; multiple Pendulum starters with no extenders common.
• Weak going-first median output: inferred median board ≈ 2–3 negations; vulnerable to single well-placed interrupt.
• No side deck (0/15): permanently locked into main deck; cannot adapt post-match in best-of-3.
• Pendulum scale conflicts: drawing multiple scale-1 Vaylantz cards with no scale-9 setup clogs hand.
• Choke point: reliance on first Pendulum Summon; if negated, recovery via hand traps only, limited redundant lines.
• Low combo floor: interrupted lines collapse without strong GY recursion engine; dependent on specific card combinations.

Critical choke points

• First Pendulum Summon: negating the initial scale setup blocks the entire combo chain; hand-trap dependency increases sharply.
• Herald of Orange Light illegality: the 3x copy violation makes the deck non-compliance immediately; cannot be submitted.
• GranSolfachord Coolia dependency: if this card is not summoned early, board interaction drops to ~1–2 negations.
• Field Zone contention: opponent Field Spell blocks Vaylantz World effects; column-based effects (Konig Wissen, Shinra Bansho) fail if Field Zones full.
• Zero side deck: best-of-3 format locks player into unfavorable matchups with no post-game adaptation.

Evidence & confidence

• Verified: Legality status: Illegal (Herald of Orange Light 3x, copy limit 1x per Master Duel banlist).; Main deck size: 51 cards (legal range 40–60).; Extra deck size: 15 cards (legal range 0–15).; Side deck size: 0 cards (legal range 0–15).; Core card representation: 8/25 archetype standard (32%) present.; Hand-trap count: 12 cards with is_hand_trap tag.; Usage statistics available for Vaylantz archetype (25 core cards, 100% threshold met for 8 present).
• Observed: All 14 dimension_evidence claims rely on card text and inferred Pendulum mechanics; no empirical boards provided in combo data.; Archetype purity 24.2% from exact-name Vaylantz cards (16/66 total cards in main+extra).
• Inferred: Consistency P(at least one Vaylantz/Solfachord starter in hand 5) ≈ 0.84 from hypergeometric model.; Brick rate ~12% estimated from hand redundancy analysis.; Combo ceiling: GranSolfachord Coolia + Field Spell + 1–2 negations ≈ PowerIndex 58–62.; Combo median: 2–3 negation board, ~PowerIndex 52.; Interruption resilience weak: limited independent lines after first Pendulum Summon negation.; Going-first power ~54: starter reliability offset by weak median board and missing extra-deck tutors.; Going-second power ~62: hand-trap density carries the profile.; Pilotability ~40: multi-step Pendulum sequences with decision points; error tolerance low.
• Provisional: Meta Power: null (no dated metagame sample supplied; archetype meta-share unknown for Master Duel).; Format fit D13: ~35 (Master Duel legal-list compliance, but deck violates banlist; Vaylantz meta-share unknown).; Post-side reliability: cannot estimate (zero side deck); structural best-of-3 disadvantage permanent.
• Data gaps: No combos supplied in evidence: all combo floor/median/ceiling claims are inferred from card text and Pendulum mechanics; no empirical boards to validate. No tournament link: archetype meta-share, per-pilot match record, and metagame context absent. No win-rate telemetry: going-first/going-second win rates, matchup spreads, brick/starter rates, and OTK frequencies are unknown. Side deck construction: user supplied 0/15; cannot assess post-side adaptability or side-board synergy. Meta Power: cannot compute without a dated metagame sample (latest tournament results, archetype popularity, top-deck coverage).
