Heraldic Deck #642011 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±6 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Combo
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Heraldic Xyz line (Number 69 / Heraldry Crest variants, Number 18) built from Heraldic Beast GY materials via Advanced Heraldry Art and Charged-Up Heraldry; Ryzeal Detonator / Ryzeal Duo Drive pressure through Ryzeal Plugin and Ext Ryzeal
• Turn 1 (going first): Open a Heraldic Beast starter (Gryphon, Stad Whale, Leo, Unicorn) and extend into Heraldic Xyz; Infinite Impermanence or Droll-style interaction protects the first Xyz
• Turn 2 (going second): Hand traps (Ash Blossom, Infinite Impermanence, Maxx C, Droll) answer the opponent's first starter, then extend into a Heraldic Xyz from the GY
• Recovery: Heraldic Beast Leo and Stad Whale recur from the GY to refill materials; Seventh Tachyon and Bonfire search the next starter
• After siding: Not evaluable: the deck has no side deck (0 cards), so no post-side plan exists

Why it scores here

The deck is scored as a system, not as an average of its cards. Its archetype core (Heraldic Beasts plus Heraldry Xyz) has about a 64% chance of at least one starter in a 5-card opening hand, and about 85% of the deck can search or recur a starter. Interaction is layered across hand traps (Ash Blossom, Infinite Impermanence, Maxx C, Droll) and Xyz-based removal and negation, which gives reasonable going-second resilience. Convert and median output are unmeasured because there are no recorded boards, so the combo read is text-only and low confidence. The deck is split between Heraldic and Ryzeal sub-archetypes with only 25.5% exact-name purity and 17 singletons, which weakens consistency and lowers the score. Popularity and archetype usage were not counted as power. The deck is Illegal (Droll & Lock Bird at 3 copies over a limit of 1, plus two Forbidden cards), so the score is capped at 20 and reported as theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Balanced (default, unclear strategy; Midrange-leaning). Structural ≈ 53, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: 0.80*Structural(53) + 0.20*TournamentReliability(45) = 51.4; modifiers -12 gives 39.4; Illegal legality cap sets the final score at 20 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.64 · 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

• Heraldic Beast starters are plentiful and recur from the GY
• Layered hand-trap and negation suite (9 hand traps, 10 negation-text cards)
• High searcher density (12 cards) keeps the starter reachable

Weaknesses

• Illegal list: Droll & Lock Bird over copy limit, two Forbidden cards
• Split engine between Heraldic and Ryzeal lines (25.5% exact-name purity)
• No side deck and no recorded boards, so post-side and combo output are unknown

Critical choke points

• Heraldic Beast starter count in the opening hand (about 64%)
• Xyz summon legality after the Charged-Up Heraldry and Advanced Heraldry Art lines restrict Extra Deck summons

Recommended changes

Evidence & confidence

• Verified: Legality: Droll & Lock Bird 3 copies over a limit of 1; Called by the Grave and Number 60 are Forbidden; Main 40, Extra 15, Side 0; the size rules for OCG (main 40 to 60, extra up to 15) are met; Hypergeometric probabilities and usage stats from the export
• Inferred: Consistency estimates (D1, D2) from hypergeometric odds and sub-archetype split; Hand-trap and negation coverage from card-text read; Going-first and going-second plan read from card text
• Provisional: Matchup and format fit (D13); no dated metagame sample or tournament link; Meta power (null)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry in YGOVN: going-first, going-second and matchup rates are unknown Meta power is provisional without a dated metagame sample No side deck, so post-side performance cannot be assessed
