Memento Deck #759989 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Memento Link/Fusion boards (Mementotlan-Horned Dragon, Mementotlan Twin Dragon, Mementomictlan Tecuhtlica - Creation King) converting from Memento recursion in the GY; Sky Striker Ace Link boards with Surgical Striker - S.P.E.C.T.R.A. and Sky Striker Ace = Zero
• Turn 1 (going first): Open Memento starters (Angwitch, Tatsunootoshigo, Bone Party, Fusion) and search or summon into a Memento Fusion or Link; hold Ash Blossom and Droll for the first opposing searches
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence and Droll to interrupt the opponent's board, then rebuild Memento monsters from the GY through Bone Party and Mementomictlan
• Recovery: Recover Memento monsters from the GY with Mementotlan Ghattic, Akihiron and Mementomictlan Tecuhtlica effects, then re-Fusion
• After siding: Not evaluable: the deck runs no side deck (side_count 0)

Why it scores here

The deck's Memento core is accessible: the archetype core group has about a 95% chance of at least one card in a 5-card opening hand, and the Extra Deck holds strong Memento Link and Fusion finishers. Its consistency is weakened by the split engine: only 21 of 60 main cards are exact-name Memento, while 20 are Sky Striker, so the two engines compete for slots and dilute starter density. The list is illegal under the OCG banlist (3 Ash Blossom and 3 Sky Striker Mobilize - Engage!, 2 Droll and 1 Called by the Grave, all over their limits), so it receives a structural-only score capped at 25. No combo recordings or usage-based conversion data exist, so combo ceiling and median are text-only inference. Popularity and archetype usage did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary; structural weights from Midrange profile. Structural ≈ 41, Going First ≈ 38, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-6); engine conflict (-4). Final formula: No reliable metagame: 0.80*Structural(41) + 0.20*TournamentReliability(30) = 38.8; modifiers -10 gives 28.8; Illegal deck capped to 25 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Archetype core of 26 cards gives about 95% chance of a Memento starter in the opening 5
• Strong Extra Deck finishers: Creation King (3000 ATK), Horned Dragon (2850 ATK), Twin Dragon (2800 ATK)
• Layered interruption: 10 hand traps and 8 negation-text cards

Weaknesses

• Illegal under the OCG banlist (4 cards over copy limits)
• Split engine: 21 Memento and 20 Sky Striker cards dilute starter density
• No side deck, so no post-side plan
• No combo or tournament evidence to confirm the line works

Critical choke points

• Single-Fusion or Link material chains that depend on a Memento in hand or GY
• Sky Striker Mobilize - Engage! and Ash Blossom are both over copy limits, so one must be cut for legality

Recommended changes

Evidence & confidence

• Verified: Illegal status: 4 OCG copy-limit violations listed in legality; Deck composition: 60 main, 15 extra, 0 side; 21 exact-name Memento and 20 Sky Striker cards; Usage: core group 26 cards, 14 of 25 core cards present
• Observed: No combo boards recorded, so no observed conversion or floor data
• Inferred: Archetype core P(≥1 in opening 5) ≈ 0.95 from hypergeometric draw table; Interruption, going-second and endboard scores are read from card text
• Provisional: Meta Power: null; no dated metagame sample; Format fit (D13) rests on no tournament context
• 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, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck has no title (Deck.Title null) and no side deck
