Security Block — Power Evaluation

Final Score: 33 ± 6 · Confidence: Medium

  • Intrinsic: 32 · Deck: 35 · Meta: provisional
  • Primary role: Utility

Why it scores here

Security Block is a purely defensive Quick-Play that only prevents battle damage and battle destruction of one Cyberse monster for a turn, so it converts into almost no winning value: zero combo appearances, no disruption of the opponent, and no card advantage. Its only realistic home is Cyberse decks (@Ignister, Mathmech, Code Talker) where a Cyberse body is reliably on board, but even there it is a low-count tech (avg 1.4 copies) rather than a core engine piece. Notably its 0 ATK/DEF and lack of a body earn it nothing here — the score is driven entirely by reliability, interaction quality, and deck cost. Because the effect is reactive and narrow, it sits well below generic interaction staples.

Axis scores

Axis Score Evidence
Accessibility 45 Quick-Play that needs a Cyberse monster already on the field to be live, and no searcher route is shown in evidence (inferred).
Combo & Conversion 12 Appears in 0 recorded combos and does nothing on its own, building no board (verified/observed).
Resource Economy 20 Pure -1 defensive trick that refunds no cards and generates no advantage (verified).
Effect & Interaction 15 Only prevents battle damage and battle destruction of your own Cyberse monster; it disrupts nothing on the opponent's side (verified).
Material Utility 8 A Spell Card, so it cannot be used as material or provide a body/name/level, and offers no value when effects are irrelevant (verified).
Resilience & Flexibility 25 Usable on either player's turn but dead without a Cyberse on board and provides no protection against effects or removal (inferred).
Deck-Building Efficiency 38 Ran as a 1-of (avg 1.4 copies) in a handful of Cyberse decks, so slot cost is low but it is essentially filler (observed).

Calculation

Weight profile: Utility / no clear role (default). Intrinsic ≈ 32, Deck ≈ 35, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Protects a Cyberse monster from battle destruction for a turn
  • Prevents battle damage for both players that turn, useful as a defensive combat trick
  • Quick-Play timing lets it be used reactively on either turn

Weaknesses

  • Does nothing to stop opponent effects, negates, or removal
  • Requires an existing Cyberse monster on the field to be live
  • No card advantage and no combo ceiling — zero recorded combo appearances
  • Narrow Cyberse-only application limits its homes

Counters / choke points

  • Effect negation such as Ash Blossom & Joyous Spring or Solemn Judgment
  • Non-battle removal (banish, destroy, or effect-based) that ignores the battle protection
  • Preventing or clearing the Cyberse target so the card has no legal target

Best use

Defensive combat protection for a Cyberse monster. Decks: @Ignister, Mathmech, Code Talker, A.I.. Suggested copies: 1.

Evidence & gaps

  • Verified: Card text: Target 1 Cyberse monster on the field; this turn neither player takes battle damage, also that monster cannot be destroyed by battle.; Type: Quick-Play Spell Card, no ATK/DEF/Level, no archetype.
  • Observed: Ran in 5 sample decks, all main deck, avg 1.4 copies (4 decks at 1 copy, 1 deck at 3).; Archetype spread across @Ignister, Mathmech, A.I., and Code Talker; combos_evidence shows 0 appearances.
  • Inferred: Being a Spell, it cannot serve as material and provides no body value.; Its offensive ceiling is nil since it grants no advantage and disrupts nothing on the opponent's field.
  • Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
