Legality
Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Memento monsters (Mementoal Tecuhtlica - Combined Creation, Mementomictlan Tecuhtlica - Creation King, Mementotlan Twin Dragon) and large beaters; Phantom Beast Chimera fusion beats, but only Guardian Chimera is present from that core
- Turn 1 (going first): Open a Memento searcher or Fusion starter and build toward a Memento Fusion or Special Summon chain; Raigeki and Metaltronus are conditional follow-ups
- Turn 2 (going second): Hold Ash Blossom, Nibiru, Droll & Lock Bird and Infinite Impermanence to interrupt the opponent's opening, then pivot to Memento recursion
- Recovery: Recover Memento monsters from the GY via Mementotlan Ghattic, Bone Party and Angwitch; Mementotlan Dark Blade and Fuwalos add card economy
- After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists in the evidence
Why it scores here
The deck is scored as a system, not as an average of its cards. Its real engine is the Memento sub-archetype, with 12 searcher-text cards and a 6-copy core that opens at least one copy in about 47% of opening hands (Inferred). The listed Phantom Beast Chimera core is mostly absent: only Guardian Chimera is in the Extra Deck, against an archetype-standard core that includes Chimera the Illusion Beast, Gazelle and Chimera Fusion. Interaction is the deck's strongest area: 10 hand traps and 28 removal-text cards give a P(at least one hand trap in a going-second 6-card hand) of about 74% (Inferred). Popularity and archetype usage did not earn points, and the deck is capped because it breaks the OCG copy limit on Ash Blossom and Super Polymerization and runs 18 Extra Deck cards against a limit of 15. There is no combo data and no Side Deck, so the ceiling and post-side scores are Inferred only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 45 | Memento core 6 copies gives P(open ≥1 in 5-card hand) ≈ 0.47; 12 searcher-text cards help, but Chimera core is missing; Inferred |
| D2 | Opening-Hand Quality & Brick Management | 42 | 52 main with 9 singleton slots, 16 tech cards (Raigeki, Metaltronus, Infinite Impermanence) and no side to fix dead draws; Inferred |
| D3 | Combo Conversion & Ceiling | 52 | Creation King, Mementoal Tecuhtlica (5000 ATK) and Twin Dragon give a high ceiling on paper, but there are no parseable boards to confirm it; Inferred |
| D4 | Combo Floor & Median Output | 40 | No recorded boards, so median output is unknown and is set low for lack of evidence; Inferred |
| D5 | Interruption Resilience & Route Redundancy | 58 | 10 hand traps across multiple names plus Mementotlan Cranium Burst and Mementotlan Mace allow several independent disruption answers; Inferred |
| D6 | Resource Economy, Recovery & Grind | 55 | Memento GY recursion (Ghattic, Bone Party, Angwitch) and Dark Blade/Fuwalos draw give a reasonable grind, but no resource signature data exists; Inferred |
| D7 | End-Board & Interaction Quality | 68 | 3x Ash Blossom and 2x Droll-class interaction, plus Nibiru and Infinite Impermanence, give a dense interaction layer; Inferred from card text |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second value comes from hand traps and Memento boards; no going-second combo split exists; Inferred |
| D9 | Offensive Pressure & Closing Power | 62 | Multiple high-ATK boss monsters (5000, 3000, 2850, 2800 ATK) give closing power on the field; Verified stats, Inferred conversion |
| D10 | Main Deck Efficiency & Flexibility | 40 | 52 main cards are within the 40–60 range, but 16 tech slots and two over-limit cards reduce coherence; Inferred |
| D11 | Extra Deck Efficiency & Coverage | 40 | 18 Extra Deck cards exceed the 15-card limit by 3, which is a legality violation rather than a flexibility gain; Verified |
| D12 | Side Deck Adaptability | 15 | No Side Deck at all, so no post-side adaptability exists in best-of-3 play; Provisional |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link and no dated meta sample, so format fit is only partially supported; Provisional |
| D14 | Pilotability & Error Tolerance | 35 | Memento chains and Fusion steps with multiple decision points increase error risk; Inferred from card text |
How the score was computed
Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegal copy-limit violations (-6); Extra Deck over size (-2); No Side Deck (-4). Final formula: 0.80*Structural(50) + 0.20*TournamentReliability(42) = 48.4; modifiers -12 → 36.4; capped to 30 because legality is Illegal (theoretical/structural only, no normal Final Contextual score)
Probability & combo summary
- Opening a starter: P(≥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
- Dense interaction: 10 hand traps and 28 removal-text cards
- Memento recursion gives card economy after disruption
- High-ATK boss monsters close the game
Weaknesses
- Illegal under OCG copy limits and Extra Deck size
- Chimera archetype core largely absent; deck is a Memento build with a Chimera label
- No Side Deck
- Heavy chain dependence raises error rate
Critical choke points
- Memento searchers and Fusion starters are the only consistent starts; if Memento monsters are not drawn, the deck relies on Raigeki and Metaltronus
- Over-limit Ash Blossom and Super Polymerization cannot be run as built
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One Ash Blossom & Joyous Spring and one Super Polymerization | Legal copies or a different tech card | Required to make the list legal under OCG copy limits |
| 2 | Extra Deck cards down to 15 | None | Extra Deck is 3 over the size limit |
| 3 | Off-plan tech cards such as Raigeki or Metaltronus, if not needed | A 15-card Side Deck with Memento or Chimera-relevant answers | Adds post-side adaptability and reduces dead draws |
Evidence & confidence
- Verified: OCG legality: Ash Blossom and Super Polymerization exceed their copy limit (3 vs 2); Extra Deck size is 18 against a maximum of 15; Main Deck size of 52 is within the 40–60 range; No Side Deck is present
- Inferred: Memento is the real engine; archetype core P(open) ≈ 0.47; Hand-trap density gives P(≥1 hand trap going second) ≈ 0.74; Brick risk is moderate-to-high from 16 tech slots
- Provisional: Meta power and format fit (no dated meta sample or tournament link); Post-side plan (no Side Deck)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first/second, matchup, brick or starter rates Meta Power is Provisional without a dated metagame sample No Side Deck, so post-side adaptability cannot be evaluated
