Mecha Phantom Beast Deck #769630 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±6 · Confidence: Low)

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

Legality

Main 56 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Clear Wing and Crystal Clear Wing Synchro boards built from Speedroid starters, with Over Synchro and Clear Wing Fast Dragon as the closers; Hi-Speedroid Synchro and Link extenders; Mecha Phantom Beast Auroradon would add a Link route but is Forbidden and is not usable in this list
• Turn 1 (going first): Open a Speedroid starter (Taketomborg, Colonel Clackers, Terrortop, CarTurbo, Marble Machine) and reach a Synchro via the Roid tuners, Wing Synchron and Red-Eyed Dice
• Turn 2 (going second): Use the negations and hand traps (Ash Blossom, Ghost Belle, Maxx C, Droll & Lock Bird, Infinite Impermanence, Synchro Emergency) to interrupt the opponent's first board, then extend through the Speedroid engine
• Recovery: Speedroid searchers (Terrortop, Marble Machine, Scratch, Piper) and GY-revival effects (Den-Den Daiko Duke, O-Lion, Cork Shooter) rebuild the board from a partial hand
• After siding: Not assessable: the deck has no side deck, so there is no post-side plan

Why it scores here

The score reflects the deck as a connected system: a Speedroid starter-to-Synchro engine with Clear Wing closers and a dense negation package, scored on consistency, interaction and resilience rather than by averaging any card's power. The list is Illegal in OCG: three Forbidden cards (two Crystal Wing Synchro Dragon, one Baronne de Fleur, one Mecha Phantom Beast Auroradon) and 16 Extra Deck cards against a limit of 15. The Illegal status caps the score, so this is a structural read only. Consistency is moderate: the archetype core opens about 60% of the time in a 5-card hand, but many of the 56 Main Deck slots are off-archetype tech and the exact-name archetype purity is only 4.2%. The empty Side Deck removes any post-side plan. No combo boards, tournament record or meta data are present, so the floor, median and ceiling are inferred from card text and the scores carry Low confidence. Popularity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Combo secondary; no more than one secondary is used for the blend. Structural ≈ 47, Going First ≈ 46, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist exposure (-10); extra deck over limit (-3); empty side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list capped low; total modifiers -15

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.6 · 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 negation and hand-trap package (18 negation-text cards, 9 hand traps)
• Multiple Speedroid starters and searchers for consistent opening access
• Clear Wing closers provide strong end-board ATK and interaction

Weaknesses

• Illegal list: three Forbidden cards and 16 Extra Deck cards
• Low archetype purity (4.2% exact-name) with a 13-way sub-archetype spread
• No side deck, so no post-side adaptation

Critical choke points

• Speedroid tuners in hand for Synchro access
• Crystal Clear Wing Synchro extenders depend on the Clear Wing board
• Forbidden Synchro and Link cards would need replacing before the list can be legal

Recommended changes

Evidence & confidence

• Verified: Illegal status: 3 Forbidden copies in the Main/Extra Deck; Extra Deck of 16 cards against an OCG maximum of 15; Side Deck of 0 cards; Archetype purity 4.2% (exact-name); Hypergeometric starter probability 0.5984 for the archetype core in a 5-card hand
• Inferred: Consistency and brick estimates from composition and hypergeometric draws; Interaction quality from negation and removal text hints; Going-first and going-second estimates from card text
• Provisional: Meta Power and matchup fit (no dated meta sample); Tournament reliability (no tournament link)
• 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 win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
