Memento Deck #767480 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 14 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Memento board pressure: Mementotlan / Mementoal recursion and Level 9+ Memento beaters (Mementomictlan Tecuhtlica - Creation King 3000 ATK, Mementotlan-Horned Dragon 2850 ATK, Mementotlan Twin Dragon 2800 ATK) once the extra-deck Fusion and Link pieces are live.; Fusion and Link extra-deck follow-ups (Guardian Chimera and Mudragon are absent from the list; Garura, Favorite HERO Flame Wingman, Surgical Striker - S.P.E.C.T.R.A., Gorgon of Zilofthonia and Herald of Mirage Lights are present).
• Turn 1 (going first): Open with the Memento core (Mementotlan Angwitch, Tatsunootoshigo, Bone Party, Fusion) to search and summon into Memento monsters; the 37-copy archetype core gives Inferred near-certain (0.9975) access to at least one Memento card in a 5-card opening hand. The line is text-derived and has no recorded boards.
• Turn 2 (going second): Respond with Ash Blossom, Ghost Ogre and Droll & Lock Bird as hand traps (P(at least one hand trap in 6 cards) is about 0.58, Inferred) while holding Memento starters; the 3-copy limit issue on Ash Blossom must be resolved before this plan is legal.
• Recovery: Recycle Memento monsters and spells from the GY through Mementotlan Ghattic, Mementotlan Akihiron and Mementotlan Shleepy, and rebuild through Mementomictlan's special summon text; these are text-derived recovery routes, not measured ones.
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot adapt between games of a best-of-3 set.

Why it scores here

The deck is Illegal as submitted: Ash Blossom & Joyous Spring and Super Polymerization are each run three times against an OCG Semi-Limited limit of two, so it receives a capped, structural-only score rather than a normal contextual score. Within that cap, the Memento core is highly accessible (the 37-copy archetype group gives Inferred near-certain opening access), and the deck has strong interaction density from hand traps and removal text, plus Level 9+ Memento beaters that give it a closing route. Its main weaknesses are the empty side deck, a low exact-name archetype purity of 34.8% with 19 generic and 45 off-archetype copies, and the complete absence of recorded boards, so floor, median and ceiling are text-only inference. The score was not produced by averaging individual card scores, and popularity or usage stats were not credited as power, since the Memento core appears in the archetype stats mainly as confirmation that the list is real.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56.6, Going First ≈ 58, Going Second ≈ 53, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy-limit violation (-15); Empty side deck (-3); No recorded boards (-2). Final formula: Illegal cap applied: 0.80*Structural(56.6) + 0.20*TournamentReliability(50) = 55.3, then context modifiers -20 (copy-limit violation -15, empty side deck -3, no recorded boards -2), rounded and capped at 35; Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 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

• Archetype core is highly accessible (37 copies, Inferred 0.9975 opening access)
• Dense interaction text: 7 hand traps and 27 removal-text cards
• Multiple Level 8+ Memento beaters and Fusion/Link extra-deck options

Weaknesses

• Illegal copy-limit violations on two cards (Ash Blossom, Super Polymerization)
• Empty side deck: no post-side plan
• Low exact-name archetype purity (34.8%) with many generic and off-archetype copies
• Zero recorded boards, so the combo ceiling and floor cannot be measured

Critical choke points

• Ash Blossom and Super Polymerization are over the OCG limit, so the deck cannot be played as built
• Memento monsters that must be destroyed and recycled for most lines leave no redundant recovery if the core is removed early
• Mementoal Tecuhtlica - Combined Creation is a single-copy extra-deck boss, so the top-end finisher is a one-card dependency

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring and Super Polymerization each run 3 copies against a legal limit of 2 under OCG rules; Main deck 55 cards (within 40-60), Extra 14 (within 0-15), Side 0 (within 0-15); Limited cards Droll & Lock Bird, Harpie's Feather Duster, One for One, Pot of Prosperity, S:P Little Knight are each run at 1 copy (legal); Archetype purity: exact-name Memento 24 copies, purity 34.8%; Usage statistics show the Memento core is present in this list (core present 68%)
• Inferred: D1 engine accessibility from hypergeometric archetype-core probability of 0.9975; D2 brick management from copy histogram and one-of tech density; D3/D4 combo ceiling and floor from card text only; no boards; D7 interaction quality from text role hints (hand traps and removal/negation text); D8 going-second hand-trap access (0.5767 for at least one in 6 cards)
• Provisional: Meta Power (null) and D13 matchup/format fit, which need a dated metagame sample; Tournament reliability component, because no tournament link exists
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second and matchup rates unknown Meta Power is provisional unless a dated metagame sample is supplied No side deck: post-side adaptability cannot be measured No guides attached (total_guides 0)
