Memento Deck #765768 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±8 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Summon Cyber End Dragon (4000 ATK, piercing) or a Cyber Dragon boss through Cyber Dragon starter lines that Special Summon from hand or GY via Cyber Dragon Core, Nachster, Herz, Cyber Emergency and Cyber Repair Plant.; Chimeratech Rampage Dragon and Megafleet Dragon fusions, Cyber Dragon Nova and Infinity Xyz lines, and Power Bond for burst ATK.
• Turn 1 (going first): Open a Cyber Dragon starter (Core or Nachster, or Cyber Dragon once the opponent has a monster), search a Cyber spell/trap or Cyber Emergency, then fuse or Xyz into a boss from the Extra Deck.
• Turn 2 (going second): Use Droll & Lock Bird (hand trap, 2 copies) and Cybernetic Overflow (2 copies) to break the opponent's first play, then rebuild Cyber Dragons from the GY with Repair Plant or Nova.
• Recovery: Cyber Repair Plant and Cyber Emergency recur from the GY; Cyber Dragon Nova detaches to revive Cyber Dragons; Cyber Dragon Core can banish itself from the GY to summon a Cyber Dragon.
• After siding: Not applicable: Duel Links has no Side Deck in this format (side_count 0), so there is no post-side plan.

Why it scores here

The deck reliably opens a Cyber Dragon starter: three Cyber Dragons, three Cyber Emergency, two Repair Plant and several single-copy starters give about a 0.997 chance of at least one archetype card in a 5-card opening hand (Inferred, hypergeometric). Conversion rests on the Extra Deck, with four fusions, three Xyz and two Links, and the single recorded combo reaches a ceiling of 100 with 3.5 boards per starter. Only one recorded board exists, so the median and floor are not measured and are scored conservatively. Interaction is real (two Droll & Lock Bird, two Cybernetic Overflow, Forbidden Droplet, and negation text on Regulus and Heosvarog), which supports the going-second plan. The score comes from consistency, median-capable output and interaction on the whole system; popularity and the average of individual card scores did not contribute, and the format has no side deck to adapt with.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 64, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: Extra-Deck dependence (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 63.98 -> 64, TR 57, 0.80*64 + 0.20*57 = 62.6, with -1 modifier = 61.6 -> 62

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.43 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex 100, median 100, board-per-starter 3.5
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Three Cyber Dragons plus Emergency, Repair Plant and Core give several independent starters
• Nine Extra Deck cards with multiple boss options: Cyber End Dragon, Rampage, Megafleet, Nova, Infinity
• Layered interaction: two Droll & Lock Bird, two Cybernetic Overflow, Forbidden Droplet, negation text on Regulus and Heosvarog

Weaknesses

• Only one recorded combo board, so the median and floor are not measured
• Several main cards are conditional on an opponent monster (Cyber Dragon, Jormungardr), creating dead-draw risk
• Tech cards (Droll, Book of Eclipse, Forbidden Droplet) reduce starter density when their targets are absent

Critical choke points

• Cyber Dragon Core and Nachster as early Special Summon sources when the opponent has no monster
• Cyber End Dragon and Nova as the main closing Extra Deck threats; loss of Extra access ends the plan

• Provisional: Meta Power (null); Matchup coverage and format fit (D13), no tournament data
• Data gaps: Only one recorded combo board (n=1): median, floor, and starter diversity are not measured usage_statistics in_this_deck flags conflict with the deck's card list: Heosvarog, Cyber End Dragon, Cyber Dragon Nova and Cyber Dragon Infinity are listed in the Extra cards but marked in_this_deck=false; core_present_pct 61.9 is therefore unreliable and was not used for scoring no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) no side deck format data (Duel Links: side_count 0) guides are thin: 2 of 3 guides have no sections and one snippet is empty
