Memento Deck #765147 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±10 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Special Summon and Fusion-Summon Memento boss monsters (Mementoal Tecuhtlica - Combined Creation at 5000 ATK, Mementomictlan Tecuhtlica - Creation King, Mementotlan Twin Dragon, Mementotlan-Horned Dragon) and attack through the board; Link and Fusion pressure from Underworld Goddess of the Closed World, Guardian Chimera, and Predaplant Dragostapelia, with Underworld Goddess able to negate all opposing monsters' effects
• Turn 1 (going first): Open a Memento starter (Shleepy, Angwitch, Tatsunootoshigo, Ghattic, Akihiron, or Dark Blade), search or Special Summon a second Memento, and build toward a Fusion or Link boss while holding Forbidden Droplet or removal text in reserve
• Turn 2 (going second): Use Forbidden Droplet and Book of Eclipse to blunt the opposing board, then rebuild through Memento recursion (Ghattic, Akihiron, Bone Party, Horned Dragon from the GY) into a boss
• Recovery: Recover from the GY: Ghattic adds or summons Memento cards, Akihiron recovers banished or GY Memento cards, Horned Dragon Special Summons from the GY with three different-name Memento monsters, and Creation King adds Mementomictlan
• After siding: Not applicable: Duel Links has no side deck (Side Deck size 0 and the format is a single-game ladder)

Why it scores here

The deck reliably opens a functional Memento plan: the 18-copy archetype core has a hypergeometric P(at least one in a 5-card opening hand) of 0.9944, and the 12 searcher-text cards reach 0.9399, so the engine is almost always live on turn 1 (Inferred). Its floor is held up by recursion from the GY (Ghattic, Akihiron, Bone Party, Horned Dragon) and by 17 removal-text cards, and its ceiling comes from high-ATK bosses (Creation King 3000, Twin Dragon 2800, Horned Dragon 2850, Combined Creation 5000) and Underworld Goddess, which can negate all opposing monster effects. No recorded boards exist, so the combo floor, median, and ceiling are text-only inferences and are kept near the middle of the range. The score was not taken from Memento's popularity, from averaging card scores, or from a win rate, since none exist in the evidence; Meta Power is provisional and was dropped from the formula.

Dimension scores

How the score was computed

Strategy profile: Midrange, meta-neutral (D13 dropped, remaining weights renormalised over 95). Structural ≈ 66, Going First ≈ 70, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 64. Modifiers: Off-archetype dilution (-2); Redundant engine routes (1); Narrow Level 1 Xyz payoff (-1). Final formula: 0.80*Structural(66.1) + 0.20*TournamentReliability(64) + context modifiers (-2) = 63.7, rounded to 64; Meta Provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core present at 0.9944 and searcher access at 0.9399 in opening hands
• Multiple GY recursion routes keep the deck alive after disruption
• Extra Deck carries 2700–5000 ATK bosses plus Underworld Goddess negation
• Compact 30-card main with a legal list and no copy-limit issues

Weaknesses

• No recorded boards, so the combo ceiling and median are untested
• Six Book of / Forbidden staples dilute the Memento engine
• No side deck, so the adaptability dimension gives no evidence
• Lyrilusc (Limited, Level 1 material) is awkward to use

Critical choke points

• Mementoal Tecuhtlica - Combined Creation is a single copy that needs five other different-name Memento monsters to be shuffled in, so it is hard to replace once lost
• Forbidden Droplet (3) is the only going-second answer that is not a boss

Recommended changes

Evidence & confidence

• Verified: Main 30 and Extra 9 within duel-links size rules; no violations; Lyrilusc is Limited at 1 copy and run at 1 copy, which is legal; Archetype core group P=0.9944 and searcher group P=0.9399 from the hypergeometric table; Usage-statistics core coverage: 19 of 21 core cards are present; the evidence's missing core cards list is wrong because its in this deck flag ignores the Extra Deck
• Inferred: Consistency estimates from the hypergeometric model; Engine-route redundancy and recursion resilience from card text; Ceiling and interaction density from card text
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (tournament data unavailable); Median and floor (no recorded boards)
• 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 usage statistics in this deck flag ignores Extra Deck cards (Creation King, Twin Dragon, Chimera, Lyrilusc, Goddess, Little Knight, Dragostapelia show false), so missing core cards is overstated; actual missing core is Masquerena and Cranium Burst guide data snippet is empty ( ) with no sections No win-rate telemetry exists in YGOVN; Meta Power is Provisional
