Legality
Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s). Restricted cards run: Bonfire (Limited), Called by the Grave (Limited), Crossout Designator (Limited), Herald of the Arc Light (Limited), Maxx "C" (Limited).
Identity & game plan
- Win condition: OTK via Melffy swarm and Call of the Grave recursion
- Turn 1 (going first): T1: set key traps/Quick-Play Spells, swarm with Beast tokens, pop board with Infinite Impermanence/Maxy "C"; go wide and push for lethal.
- Turn 2 (going second): Six-card hand enables early trap/Quick-Play setup; answer, then develop swarm and OTK.
- Recovery: Restart engine with Call of the Grave recursion or token re-summon; use Herald of the Arc Light/Impermanence for disruption and rebuild.
- After siding: Side into broad removal/anti-synchro tools; keep Melffy swarm enablers and hand traps.
Why it scores here
The deck runs a high-consistency Melffy swarm engine with strong OTK potential, but is currently Illegal (over-limited copies of Maxx "C", Called by the Grave, Bonfire) which caps practical reliability. Hand consistency is moderate and brick-prone, combo ceiling is solid once assembled, and disruption/interruption resilience is above average thanks to multiple negation and board-clear options. Resource grind and matchup coverage are weaker, dragging the floor down; post-side adaptability is limited by narrow side choices.

How the score was computed
Strategy profile: Balanced (Combo-focused). Structural ≈ 58, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal cards (-10); Format adaptability (-5); High combo complexity (-5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
- Combo output: best PowerIndex 70, median 55, board-per-starter 2.6
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Strong OTK potential when assembled
- Good negation and board-clear redundancy
- Six-card hand enables early disruption
Weaknesses
- Illegal card count threatens legality
- Brick risk on low-consistency hands
- Limited extra deck coverage and side flexibility
Critical choke points
- Dependence on specific swarm pieces
- Lack of reliable draw
- Format fit unknown without meta
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Maxx "C" (x3) → reduce to 1 | Currently over-limited; bring to 1 to match format rules. | |
| 2 | Called by the Grave (x2) → reduce to 1 | Over-limited; reduce to legal copy count. | |
| 3 | Bonfire (x2) → reduce to 1 | Over-limited; reduce to legal copy count. | |
| 4 | Add consistent hand-trap or draw support | Improve brick management and grind. | |
| 5 | Test 1-2 anti-synchro tech cards for side | Raise D12 adaptability versus common threats. |
