Main 40 / Extra 15 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Xyz-summon Level 4 Exosister Xyz monsters (Mikailis, Magnifica, Karmael, Kaspitell) off the Exosister engine and attack through the board; Graveyard-triggered Xyz summons and hand-trap-protected boards (Ash Blossom, Ghost Ogre, Maxx C, Dominus Purge)
- Turn 1 (going first): Pax or Betrayal to add Exosister monsters, then Elis or Martha from hand to build a Level 4 board for a Xyz summon
- Turn 2 (going second): Hold Maxx C, Ash Blossom, Ghost Ogre or Dominus Purge to interrupt the opponent's first play, then rebuild through Exosister searchers
- Recovery: Exosister monsters in the GY re-enable Xyz summons; Irene and Sophia draw to refill the hand
- After siding: No side deck is registered, so there is no post-side plan to evaluate
Why it scores here
The deck reliably opens an Exosister starter: six copies of Elis and Martha and six searcher-text cards give roughly a 58 percent chance of at least one Elis or Martha in a five-card opening hand (Inferred hypergeometric estimate). Its conversion ceiling comes from the Level 4 Exosister Xyz line (Mikailis, Magnifica, Karmael, Kaspitell), which is consistent but has no recorded boards to confirm its median output. Interaction is the strongest area: Ash Blossom, Ghost Ogre, Maxx C, Dominus Purge and Dominus Spark cover both turns of play, which earns the going-second score. Popularity did not earn points: Exosister is a common archetype, and the score comes from consistency, interaction and the extra-deck conversion, not from averaging card scores. Two Level 12 Xyz monsters (Divine Arsenal, Super Starslayer TY-PHON) have no Level 12 materials in the Main Deck, so they are weak extra-deck slots and pull the score down.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one of 6 Elis/Martha in a 5-card opening hand) is about 0.58; 6 searcher-text cards give P of about 0.82 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | Six hand traps and Dominus cards are dead when not needed, and 27 of 40 cards are off-archetype copies by exact name, which raises brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 65 | Level 4 Exosister Xyz ceiling is high (Mikailis 2500 ATK, Magnifica 2800 ATK, Karmael 2600 ATK), but no recorded boards exist (Inferred) |
| D4 | Combo Floor & Median Output | 52 | No combo boards supplied, so the median is text-only and unknown; placed slightly below the ceiling (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Multiple hand traps and independent starters (Elis, Martha, Stella, Sophia, Irene) give some route redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 58 | Pax costs 800 LP per use and Xyz summons consume material; GY recursion helps recovery (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | Ash Blossom, Ghost Ogre, Maxx C, Dominus Purge, Dominus Spark and Returnia give layered interaction (Inferred semantic read from card text) |
| D8 | Going-Second & Board-Breaking Power | 62 | Hand traps plus Dominus Purge answer the opponent's first play on the going-second turn (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Level 4 Xyz ATK values are high, but there is no recorded closing data and no Number 104 in the Main Deck (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 68 | 40 Main Deck cards with 18 distinct cards and mostly 3-copy staples; no wasted deck size (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 50 | Zeus and TY-PHON need Level 12 materials that the Main Deck does not contain; Masquerade needs three Level 4 monsters, so about 2 to 3 Extra slots are weak (Inferred from card text) |
| D12 | Side Deck Adaptability | 35 | No side deck is registered (side count 0), so post-side adaptability is unsupported (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; Provisional only |
| D14 | Pilotability & Error Tolerance | 55 | Multi-step Xyz chains and GY-triggered effects demand real sequencing, but the decision tree is familiar to Exosister pilots (Inferred) |
How the score was computed
Strategy profile: Combo primary, Midrange secondary (hand-trap defence weighted in D5/D7). Structural ≈ 60, Going First ≈ 58, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Dead extra-deck slots (-2); Engine conflict (-2); Banlist exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 59.8, TR 55, combined 58.8, modifiers -4 gives 54.8, rounded to 55
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.58 · 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
- Strong hand-trap suite (Ash Blossom, Ghost Ogre, Maxx C, Dominus Purge) for going second
- Level 4 Exosister Xyz line gives high ATK boss monsters
- Compact 40-card main deck with 3-copy staples
Weaknesses
- Two Level 12 Xyz monsters with no Level 12 materials in the Main Deck
- No side deck registered
- Off-archetype copies (Dominus, Mulcharmy, Seventh, generic) reduce engine coherence
Critical choke points
- Elis or Martha in the opening hand (about 0.58 for a 5-card hand, Inferred)
- Pax 800 LP cost when life points are low
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Divine Arsenal AA-ZEUS - Sky Thunder | A second Level 4 Exosister Xyz such as Exosister Asophiel or Exosister Gibrine | Level 4 Exosister Xyz have usable materials on this Main Deck; Zeus has no Level 12 materials to summon with |
| 2 | Super Starslayer TY-PHON - Sky Crisis | A Level 4 Exosister Xyz or a second Exosister Kaspitell | TY-PHON needs Level 12 monsters or a rare alternate condition, so it is a dead slot in this list |
Evidence & confidence
- Verified: Main 40, Extra 15, Side 0 legal for master-duel (BanMasterDuel); Maxx C Limited at 1 copy, legal; Card text for all 30 listed Main Deck cards and 15 Extra Deck cards
- Inferred: Hypergeometric starter and searcher probabilities; Hand-trap interaction density from card text; Dead extra-deck slots from Level 12 material requirement
- Provisional: Meta power and matchup fit (no dated meta sample); Tournament reliability (no tournament link)
- Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first, going-second, matchup, brick or starter rates Meta Power provisional without a dated metagame sample No side deck registered, so D12 is unsupported Data inconsistency: Exosister Kaspitell (2 copies in the cards list) and Divine Arsenal / TY-PHON are flagged in_this_deck false in usage_statistics; the cards list was trusted
