Mecha Phantom Beast Deck #774144 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Stun, Midrange
• Format: tcg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link-based R.B. board (R.B. Link monsters with R.B. Stage Landing / Funk Dock recursion) converting into attack pressure; Mecha Phantom Beast tokens and Mulcharmy draw add secondary pressure. No recorded boards to confirm which is primary in practice.; Brute Blues second attack and Shepherd's Crook ATK growth once R.B. monsters are linked; Sky Striker Ace Camellia is the only Sky Striker link with usable materials in this list.
• Turn 1 (going first): Open with hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Ogre) and a Normal Summon of Mecha Phantom Beast Tetherwolf or O-Lion to generate tokens, then link into R.B. monsters. Inferred from card text; not verified on boards.
• Turn 2 (going second): Hold 2-3 hand traps for the opponent's first Normal/Special Summon or Spell/Trap activation, then use Nibiru or Artifact Lancea to stop the opposing board and rebuild with R.B. Stage Landing. Inferred.
• Recovery: Use Effect Veiler, Ghost Belle, Ghost Mourner and R.B. Funk Dock to recycle Tuners and R.B. cards from the GY, and Lambda Cannon to re-add an R.B. monster from the GY. Inferred from text.
• After siding: Not evaluable: the deck has zero Side Deck cards, so there is no post-side plan.

Why it scores here

The deck is scored as a system: its Toolbox structure is built from roughly 21 hand traps and 18 negation-text cards, which gives it reliable interaction density, and that is the strongest part of the score (D7). Its engine is a three-archetype mash (R.B. about 15 main-deck cards, Mecha Phantom Beast about 6, Mulcharmy about 6; exact-name purity 8.5%). That spread lowers engine coherence and consistency (D1, D2), and the Extra Deck is weakened by dead cards: three Sky Striker Ace links have no Sky Striker Ace monsters in the Main Deck to use as materials, and Super Starslayer TY-PHON needs two Level 12 materials that the list does not contain. No recorded boards exist, so combo ceiling and median output are text-only inferences and are weak (D3, D4). Popularity and archetype usage did not earn any points, and no card scores were averaged. Because the deck is Illegal (three copies of Ash Blossom against a Semi-Limited limit of two), it does not receive a normal Final Contextual score; the score is capped at 30 and the evaluation is structural only.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; secondary Stun informs D7/D13 read, not weights. Structural ≈ 44, Going First ≈ 42, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist_exposure (-4); engine_conflicts (-3); dead_extra_deck_cards (-2). Final formula: Theoretical: 0.80*Structural(44) + 0.20*TournamentReliability(38) = 43, then modifiers -9 = 34; capped to 30 because the deck is Illegal (structural-only, no normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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 negation package (21 hand traps, 18 negation-text cards) gives strong interaction on both turns
• Multiple redundant answers to a single disruption (Ash, Impermanence, Veiler, Ghost Belle, Ghost Mourner, Ghost Ogre)
• R.B. recursion (Stage Landing, Funk Dock, Lambda Cannon) can rebuild after board interaction

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring at 3 copies exceeds its Semi-Limited limit of 2
• Three-archetype engine with 8.5% exact-name purity hurts consistency
• Four Extra Deck cards cannot be summoned from this Main Deck (Sky Striker Ace Hayate, Kagari and Amatsu lack materials; TY-PHON lacks Level 12 materials)
• No Side Deck: no post-side adaptability

Critical choke points

• Ash Blossom & Joyous Spring copy limit: the list cannot be played legally until one copy is removed
• R.B. Link route depends on a small set of Link-able R.B. monsters in the Main Deck
• Sky Striker Link monsters need Sky Striker Ace material that the Main Deck does not provide

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring at 3 copies vs Semi-Limited limit 2 (Illegal); Main Deck 56 cards and Extra Deck 15 cards are within size rules; Copy histogram: 14 cards at 3 copies, 1 at 2, 12 at 1; Archetype purity 8.5% (6 exact-name of 71 Main Deck copies)
• Inferred: Engine accessibility via hypergeometric estimates (Stage Landing P >= 1 in 5 = 0.2487); Interaction density from card text (21 hand traps, 18 negation text, 25 removal text); Sky Striker Link monsters lack material in the Main Deck; TY-PHON lacks Level 12 materials
• Provisional: Meta power and format fit (no dated metagame sample); Side deck adaptability (no side deck); Tournament reliability (no tournament data)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no side deck — post-side adaptability cannot be measured usage_statistics in_this_deck flags are Main Deck only, so Extra Deck pieces (R.B. Brute Blues, VALCan Booster, Shepherd's Crook, Sky Striker Links, TY-PHON) show as absent despite being present in the Extra Deck list no win-rate telemetry exists in YGOVN — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
