Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Xyz boss monsters (Exosisters Magnifica, Exosister Mikailis, Exosister Gibrine) built from Exosister monsters and extended by Exosister Pax and Exosister Betrayal; Hand-trap and removal-supported board control with Raigeki, Lightning Storm and Harpie's Feather Duster
- Turn 1 (going first): Open with Exosister Elis or Martha, use Exosister Betrayal or Pax to search a second Exosister, then Xyz Summon a boss through the Exosister monsters
- Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Infinite Impermanence to interrupt the opponent's search or summon, then rebuild the Exosister Xyz line
- Recovery: Use the Exosister Deck-search effects (Betrayal, Pax, Sophia) to rebuild Exosister monsters from the Deck after a hand-trap or board wipe
- After siding: Not evaluable: the export carries no side deck (Side Deck size 0), so no post-side plan can be assessed
Why it scores here
The deck's archetype core is dense: an Exosister monster is in hand on going-first in about 97% of openings (Inferred), so the engine is usually live. Its interaction layer (Ash Blossom, Droll & Lock Bird, Infinite Impermanence, Nibiru, Iron Thunder) gives it real going-second resilience. Its conversion is limited by the missing Extra Deck bosses (Karmael, Magnifica, Kaspitell are not run) and by 25 generic or tech slots that dilute the engine. The score is not based on Exosister's popularity, and the card scores were not averaged. The list is Illegal because Ash Blossom is run three times against a limit of two, so the score is capped and this is a structural read only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one Exosister core card in opening 5) ≈ 0.97 with 27 core copies; engine goes live T1 in most hands (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | 25 generic or tech cards and 17 tech slots add brick and dead-card risk to 5-card openings (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No parseable combos; ceiling read is text-only from Exosister Xyz summon chains, with the strongest bosses not run (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards, so median output is unknown and inferred to be modest (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Nine hand traps plus Exosister Betrayal and Pax give several independent interruption routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Ten searcher-text cards and LP-costing Pax/Betrayal support rebuilding, but grind depends on LP (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | Ash Blossom, Droll & Lock Bird, Infinite Impermanence, Nibiru and Iron Thunder give layered interaction (Inferred semantic read of card text) |
| D8 | Going-Second & Board-Breaking Power | 50 | Raigeki, Lightning Storm, Harpie's Feather Duster and Swords of Concealing Light challenge boards; going-second hand-trap hit rate ≈ 0.68 (Inferred) |
| D9 | Offensive Pressure & Closing Power | 45 | Xyz bosses reach 2100–2800 ATK, but the strongest closers are absent from the list (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 55 Main Deck cards across 33 distinct names with 25 generic slots; legal but not compact (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 13 Xyz and 2 Fusion in 15 Extra slots with 10 distinct names; the Extra Deck covers the archetype but skips several of its bosses (Verified structure, Inferred coverage) |
| D12 | Side Deck Adaptability | 15 | No side deck exported, so post-side adaptability cannot be assessed (Provisional) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link or dated metagame sample; archetype usage is context only (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multiple Xyz-target and chain-timing decisions across hand traps; high decision density (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Copy-limit violation (Ash Blossom x3, limit 2) (-10); No side deck exported (-2); Illegal-status cap (0). Final formula: Final = 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*52 + 0.20*45 ≈ 51, less modifiers (-12) = 39; capped at 30 because the list is Illegal (theoretical/structural-only read)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · 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 Exosister core gives a high going-first starter rate (Inferred)
- Layered hand-trap and removal interaction supports going second (Inferred)
- Searcher and Deck-recovery text (Betrayal, Pax, Sophia) supports rebuilding (Inferred)
Weaknesses
- Illegal copy-limit violation on Ash Blossom & Joyous Spring (Verified)
- Several core Extra Deck bosses (Karmael, Magnifica, Kaspitell, Gibrine, Asophiel, Mikailis) are not run (Verified from usage stats)
- 25 generic and 17 tech slots dilute the engine and raise brick risk (Inferred)
- No side deck, so no best-of-3 plan (Verified)
Critical choke points
- Exosister Elis/Martha as the first Exosister monster in hand
- Extra Deck Xyz boss requiring two Level 4 Exosister materials
- LP cost on Pax, Betrayal and Arment
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One copy of Ash Blossom & Joyous Spring | A legal card that keeps interaction (e.g. a second copy of a non-limited hand trap) | Restores the deck to a legal OCG list before any strength read is valid |
| 2 | Two to three generic or tech slots (e.g. Triple Tactics Thrust, Swords of Concealing Light) | Exosister Karmael or Exosisters Magnifica (Extra Deck boss) | Improves the closing power and the Xyz ceiling that the usage stats show as core |
| 3 | A side deck is missing entirely | A 15-card side deck with hand-trap and boss-answer coverage | Makes best-of-3 play and post-side planning evaluable |
Evidence & confidence
- Verified: Ash Blossom & Joyous Spring is run 3 times against an OCG limit of 2 (Illegal); Main Deck 55 and Extra Deck 15 are within size rules; Archetype usage: Karmael, Magnifica, Kaspitell, Gibrine, Asophiel, Mikailis are not run
- Inferred: Exosister core starter access ≈ 0.97 on going-first; Hand-trap hit rate on going-second ≈ 0.68; Interaction layering rates the deck's going-second defence as moderate-to-good
- Provisional: Meta Power is null: no dated metagame sample or tournament link; Tournament Reliability relies on text reads, not match data
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no side deck exported — post-side adaptability cannot be scored no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
