Why it scores here

Firewall Defenser converts a Cyberse Link Summon into one extra Firewall body from the Deck, and its GY-banish replacement protects Firewall monsters from card-effect destruction. Its presence in 400 of 400 recent decks at about 2.8 copies confirms it is reliably accessible and cheap to run, but the combo evidence is a single board where the card has no recorded role, so the high board power index (100) is a property of that board and not of this card. The 400/400 inclusion and partner overlap (Transcode Talker at 99.5%) are frequency signals and were not used to raise the score; the 1200 ATK body earned nothing.

Axis scores

Axis Score Evidence
Accessibility 65 Live in 400 of 400 decks at 3 copies, but reaching the GY trigger requires a Cyberse Link Summon using it as material, so it is not a hand-opener (observed deck counts plus verified card text).
Combo & Conversion 50 One extra Deck-to-field Firewall body after the Link route, with a single recorded board and no starter, searched or payoff counts for this card (verified text, observed combo data, thin).
Resource Economy 60 Nets one body from the Deck at no card cost beyond being used as Link material, with no refuel or multi-card advantage (verified text, inference).
Effect & Interaction 35 Only a once-per-turn banish replacement against Firewall monsters destroyed by card effects; no opponent-facing negate or removal (verified text).
Material Utility 60 A Level 4 DARK Cyberse body that is a legitimate Link material, and its GY effect still works after it is sent to the GY (verified text, observed as Link fodder in the Code Talker and Mathmech homes).
Resilience & Flexibility 55 Two once-per-turn effects that work from the GY and Deck, which gives some multi-zone redundancy; no evidence of resistance to negation (verified text, inference).
Deck-Building Efficiency 75 Clean 3-copy staple with no garnet or lock; 29 decks run a single copy, so splashing or trimming is easy (observed deck distribution).

Calculation

Weight profile: 0.7 Starter/Combo enabler + 0.3 Recovery/Recursion. Intrinsic ≈ 59, Deck ≈ 60, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Reliable 3-copy inclusion across 400 recent decks in several archetypes
  • Converts a Link Summon into an extra Firewall body from the Deck
  • Cheap to run with no garnet or lock; decent Link material body

Weaknesses

  • Trigger depends on a Cyberse Link Summon; not a hand-opener
  • Only one recorded combo board and no recorded starter or payoff role for the card
  • Interaction is limited to a narrow banish replacement for Firewall monsters

Counters / choke points

  • Effects that negate the Link Summon before the GY trigger resolves (inferred; not tabled in the evidence)

Best use

Link-fodder GY trigger for a Firewall body; Firewall protection. Decks: Firewall, Code Talker, Mathmech, @Ignister. Suggested copies: 3.

Evidence & gaps

  • Verified: GY trigger on Cyberse Link Summon material; Deck-to-field Firewall summon; once-per-turn on each effect; banish replacement for Firewall monsters destroyed by card effects; Level 4 DARK Cyberse, 1200 ATK / 1500 DEF, Firewall archetype
  • Observed: Present in 400 of 400 decks, 2.84 copies average, 366 at 3 copies; Top partners Transcode Talker 99.5%, Ash Blossom & Joyous Spring 95.5%, Cynet Mining 93.8%; Combo appearance 1 board of 1; as_starter, as_searched, as_material and as_payoff all 0
  • Inferred: Link route is the main access, so the card is live mainly in Cyberse Link lines; Role as a recursion and protection piece rather than a board breaker
  • Data gaps: No banlist token; assumed 3 copies (unlimited) Only one recorded combo board, and its role counts for this card are all zero The example board's power index of 100 describes the board, not this card No rulings or detailed guide text on the card's GY timing Only one guide mention, with a general snippet
