Memento Deck #773965 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Fusion
• Format: duel-links

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion Summon Mementomictlan Tecuhtlica - Creation King and/or Special Summon Mementoal Tecuhtlica - Combined Creation as a large multi-attacking boss.; Grind with Memento destruction/search recursion, then close with Guardian Chimera, Underworld Goddess, or Lyrilusc - Assembled Nightingale direct pressure.
• Turn 1 (going first): Establish a Memento body, convert into a Fusion boss, and set Infinite Impermanence / Mementotlan Fracture Dance while keeping Ghattic, Mace, Akihiron, or Mementomictlan for follow-up.
• Turn 2 (going second): Break the board with Forbidden Droplet, Book of Eclipse, and Infinite Impermanence, then use the Memento engine to fuse into Creation King/Twin Dragon/Chimera and close with Combined Creation or Underworld Goddess.
• Recovery: Recover resources through Ghattic, Mace, Akihiron, Mementomictlan, and Mementotlan Fusion's GY-shuffle line, then rebuild a Fusion boss or Combined Creation.
• After siding: No Side Deck is present in this Duel Links list and no post-side data exists; adaptation is limited to the Main Deck flex slots.

Why it scores here

The deck's score comes from a real Memento recursion engine: roughly 0.82 chance of at least one direct engine body in the opening five, with Fusion/Bone Party plus a Memento monster available in about 0.69 of hands. It usually converts into a modest Fusion boss plus backrow rather than the text ceiling of 5000 ATK Combined Creation, and its interaction is thinner than its grind. The Extra Deck is well covered and the board-breaker package gives it a genuine going-second route, but ten one-of Main Deck slots and several conditional high-level names raise hand-quality variance. The archetype's usage share and the presence of standard Memento cards did not earn points by themselves, and the score is not an average of individual card scores; no dated metagame or recorded combo data exists, so the result is Medium confidence and provisional on matchup fit.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61, Going First ≈ 61, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 59. Modifiers: none. Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ 0.69 · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High Memento density and strong in-archetype recursion support repeated rebuilding.
• Creation King and Combined Creation give a high offensive ceiling, including a 5000 ATK multi-attacker.
• Seven Main Deck board-breaker/tech cards give a credible going-second plan.
• The 9-card Extra Deck is fully filled with core Memento Fusions plus generic removal/utility links.
• Forbidden Droplet and Infinite Impermanence provide flexible interaction against many boards.

Weaknesses

• Many one-of Main Deck slots make opening quality conditional and increase decision complexity.
• The engine often needs a Memento monster plus a Fusion/Bone Party effect rather than a single-card kill line.
• Hard interaction is limited outside Droplet, Impermanence, Ghost Belle, and Fracture Dance.
• High-level Tecuhtlica/Horned Dragon can be awkward before the GY is established.
• No Side Deck and no post-side data in this Duel Links list.

Critical choke points

• Opening a Memento body without a Fusion/Bone Party line, or vice versa.
• Resolving the first search or Fusion through negation; the deck has limited hard protection.
• Drawing high-level or situational one-ofs before the graveyard setup is online.
• No Side Deck means bad matchups cannot be reconfigured between games.

Recommended changes

Evidence & confidence

• Verified: Main Deck 30 / Extra Deck 9 / Side Deck 0 with no size or copy-limit violations.; Lyrilusc - Assembled Nightingale is Limited to 1 and the deck runs exactly 1 copy.; Card text excerpts confirm Memento destruction, search, Fusion, and recursion effects.; The resolved list contains 21 exact-name Memento cards and 10 one-of Main Deck slots.
• Observed: No parseable combo boards were supplied (0 combos).; No Side Deck is present (side_count 0).; Tournament context is unavailable; no per-pilot match record exists.
• Inferred: Opening at least one direct engine body occurs about 82% of the time in a 5-card hand.; A Fusion/Bone Party plus Memento monster two-card line is available in roughly 69% of hands.; Median output is inferred as a modest Fusion boss plus backrow, well below the 5000 ATK ceiling.; The deck has real grind through Ghattic, Mace, Akihiron, Mementomictlan, and Fusion's GY shuffle.
• Provisional: Meta Power is provisional because no dated metagame sample was supplied.; Matchup coverage and format fit are provisional without tournament data.; Side Deck adaptability is unmeasured because Duel Links uses no Side Deck here.
• 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 are 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. Usage-stat in_this_deck flags conflict with the resolved Extra Deck for several cards (e.g. Twin Dragon, Creation King, Chimera, I:P, S:P, Nightingale, Underworld Goddess are listed as missing though present); the resolved card list was treated as source of truth.
