Identity & game plan
- Win condition: Xyz summon Exosister bosses and attack for battle damage; Disrupt opponent via GY punishment and board wipes
- Turn 1 (going first): Open Martha/Pax/Betrayal to Special Summon Exosister monsters and Xyz into Mikailis/Karmael/Kaspitell with disruption
- Turn 2 (going second): Use hand traps (Ash, Maxx C, Droll, Impermanence) and board breakers (Heavy Storm, Harpie's Feather Duster, Exciton, Zeus) to clear and out opponent
- Recovery: Recover via Betrayal/Pax searches, Vadis special summon, trap set from Karmael, banish with Returnia
- After siding: No side deck (Master Duel list 0 side) so post-side unchanged
Why it scores here
This Exosister list is evaluated as a connected combo-control system, not as an average of its individual card scores. The deck reliably opens with one of many starters (Martha, Pax, Betrayal) achieving near-certain engine access (P≥1 core ~0.9999 inferred), and converts into layered Xyz boards with GY-punishing disruption. Median output is a single defensive Xyz plus hand traps, while ceiling includes Magnifica/Zeus board clears, but combo records were absent so floor/median are text-inferred. High hand-trap density and board breakers give fair going-second power, yet the lack of a side deck and missing combo telemetry lower tournament reliability. Archetype popularity in usage stats confirms accessibility but does not by itself raise the score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 82 | Archetype core group 32 copies yields P(open ≥1 in 5) ≈ 0.9999 from hypergeometric (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 75 | Copy histogram shows 8 playsets and only 10 singles; limited brick cards like Heavy Storm are 1-of (Inferred) |
| D3 | Combo Conversion & Ceiling | 78 | Card text enables Martha→Elis→Mikailis/Magnifica XYZ boards with removal/negate, but no parsed combo data (Inferred) |
| D4 | Combo Floor & Median Output | 65 | Median expected board from text is one Rank-4 Exosister Xyz plus backrow; no combo floor recorded (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 70 | Redundant starters (Martha, Pax, Betrayal, Vadis) and GY-trigger Xyz provide alternate routes after disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Betrayal/Pax/Vadis recycle monsters but limited draw power (Sophia/Irene) yields moderate grind (Inferred) |
| D7 | End-Board & Interaction Quality | 80 | Extra deck includes Karmael (negate), Kaspitell (GY lock), Mikailis (removal), Magnifica (banish+negate) plus Impermanence/Dominus Purge (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 68 | Going-second hand includes 12 hand-trap copies (P≥1 in 6 ≈0.90) and board breakers Heavy Storm/Feather Duster/Exciton (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Xyz bosses ATK 2500-3000 with Magnifica double attack and Zeus board wipe provide moderate closing power (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 80 | 40-card main with 21 distinct, 8 triples, compact Exosister core purity 52.7% exact name (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 78 | 15-slot extra all XYZ (13 Exosister/Number/Generic) covering disruption, removal, board wipe (Verified) |
| D12 | Side Deck Adaptability | 0 | Side deck count 0 (Master Duel export) so no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame sample; archetype share absent, format fit provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 75 | Simple special-summon-to-xyz lines with few decision points; Martha lock manageable (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 71, Going First ≈ 75, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 65. Modifiers: no_side_deck (-2); engine_compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Redundant Exosister starters
- High hand-trap density
- Layered Xyz disruption
- Compact 40-card main
Weaknesses
- No side deck
- Limited combo telemetry
- Reliance on GY punishment can be bypassed
- Some limited staples at 1 copy
Critical choke points
- Martha lock prevents non-Exosister special summons same turn
- If all starters discarded, hand traps alone may not develop board
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Heavy Storm | Crossout Designator | Heavy Storm often dead vs no backrow; Crossout helps vs hand traps (Inferred) |
| 2 | Ichiki Sayori-Hime | Exosister Stella third copy | Ichiki not Exosister and may conflict; more Stella improves consistency (Inferred) |
Evidence & confidence
- Verified: Legality status Legal; Main 40 Extra 15 Side 0; Extra deck breakdown 15 XYZ; Restricted cards within limits
- Observed: Usage statistics core inclusion %; Hand trap group probability from hypergeometric
- Inferred: Engine consistency P~0.9999; Combo ceiling from card text; Median board from text
- Provisional: Matchup format fit without metagame
- 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 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
