Memento Deck #772442 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 43 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Memento monsters (Mementoal Tecuhtlica - Combined Creation, Mementomictlan Tecuhtlica - Creation King, Mementotlan Twin Dragon, Mementotlan-Horned Dragon) swarming the board through Fusion/Special Summon and Memento GY recursion, then attacking through the opponent's board; Hand-trap and removal disruption (Infinite Impermanence, Ghost Ogre & Snow Rabbit, Droll & Lock Bird, Mementotlan Cranium Burst) to take over the board and keep the Memento line running
• Turn 1 (going first): Search or Special Summon Memento engine pieces (Angwitch, Tatsunootoshigo, Ghattic, Akihiron) and set up Fusion or Special Summon into a large Memento monster, keeping Ash Blossom and Ghost Ogre up for responses
• Turn 2 (going second): Hand-trap the opponent's first engine (Ash Blossom, Ghost Ogre, Infinite Impermanence, Droll & Lock Bird) and rebuild the Memento board from the GY using Ghattic, Akihiron and the Fusion spells
• Recovery: Recover from the GY through Mementotlan Ghattic, Mementotlan Akihiron and Mementotlan Bone Party, and rebuild with Mementomictlan searches
• After siding: No side deck is registered (Side Deck size 0), so there is no post-side plan; best-of-3 play is not supported by this list

Why it scores here

The Memento core (26 exact-name copies, 44.8% exact purity, with 17 generic and several related sub-archetype cards) is a real, coherent engine: the searchers and Special Summon effects (Angwitch, Tatsunootoshigo, Ghattic, Akihiron, Bone Party) are present at full copies and the core group has a high probability of at least one piece in the opening hand. Interaction is the second pillar: 10 hand traps and 7 negation-text cards give the list a strong going-second answer to an opposing engine (Inferred). The end-board ceiling comes from the Fusion and Link bosses (Creation King 3000 ATK, Twin Dragon 2800, Horned Dragon 2850, Tecuhtlica 5000), which are real closing power but are not confirmed by any recorded combo boards. The score is held down by three things: the list is Illegal under OCG limits (3 copies of Ash Blossom against a legal limit of 2), so it receives a theoretical cap rather than a normal contextual score; there are no combo boards, no tournament record and no side deck; and the Extra Deck spreads across several unrelated Link and Xyz monsters. Popularity and archetype usage stats confirm the list is real, but they did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with no secondary weighting applied; secondary strategy noted only. Structural ≈ 55, Going First ≈ 52, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-5); no Side Deck (-3). Final formula: No reliable metagame, so Meta is provisional: 0.80*Structural(55) + 0.20*TournamentReliability(45) = 53; modifiers total -8 gives 45; Illegal cap applied, final score 30, theoretical/structural only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Coherent Memento core with full copies of the main searchers and Special Summon engine pieces
• Layered interaction: 10 hand traps plus removal and negation text
• Strong Fusion and Link closing bosses with high ATK
• Strong going-second answer count

Weaknesses

• Illegal under OCG limits: Ash Blossom is run 3 copies against a legal limit of 2
• No side deck registered, so there is no post-side plan
• Extra Deck has several off-archetype Link and Xyz cards with little engine connection
• No combo boards recorded, so the ceiling and median cannot be verified

Critical choke points

• Opening hand needs a searcher or Special Summon starter; the starter count is high but the line still depends on Memento monsters being live
• Ash Blossom and the other hand traps are the only early answers, so losing them to the copy-limit cut weakens going-second play
• Fusion summons depend on specific Memento materials in hand or field

Recommended changes

Evidence & confidence

• Verified: Main deck size 43 and Extra Deck size 15 are within the OCG size rules; Ash Blossom & Joyous Spring is run 3 copies against a Semi-Limited legal limit of 2 (illegal); Droll & Lock Bird and S:P Little Knight are Limited at 1 copy each (legal); Creation King 3000 ATK, Twin Dragon 2800 ATK, Horned Dragon 2850 ATK, Tecuhtlica 5000 ATK; Memento exact-name purity 44.8%
• Observed: Archetype usage stats show Memento core cards at high inclusion (the deck runs most of them)
• Inferred: Starter access about 0.82 from the searcher group hypergeometric estimate; Hand-trap coverage about 0.82 going second; Brick and redundancy estimates from copy histogram and level spread; Interaction and closing read from card text
• Provisional: Meta power and matchup fit (no dated metagame sample)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot records are absent No win-rate telemetry in YGOVN (going-first/second, matchup, brick and starter rates) Meta Power is Provisional without a dated metagame sample No side deck registered, so post-side adaptability is unmeasurable
