Everlasting Alloy — Power Evaluation

Final Score: 46 ± 6 · Confidence: Medium

  • Intrinsic: 46 · Deck: 46 · Meta: provisional
  • Primary role: Negation/Interaction

Why it scores here

Everlasting Alloy is a conditional Quick-Play that only works while you control Jinzo: it either makes your Machine monsters immune to opponent card effects for the turn, or negates an effect that targets a Machine you control. Its power is that interaction, which is narrow (Machine-only) and gated on a specific board state, so it earns a moderate score rather than a high one. It builds no board, gains no card advantage, and is a poor material body, so those axes stay low. High deck inclusion (20 decks, 13 of them Jinzo) confirms it is a practical in-archetype pick, but that is frequency, not strength, and the 1800-level ATK and other stats earn nothing.

Axis scores

Axis Score Evidence
Accessibility 50 Spell card in 20 recent decks, mostly Jinzo, but no searcher or combo evidence to show it is reliably reached (verified deck count; no combo data).
Combo & Conversion 15 Text only; it does not add bodies or a board on its own, and no combo boards were supplied (verified text, no combo evidence).
Resource Economy 25 No draw, search, or refuel in the text, and it is a one-for-one spell used for protection (verified text).
Effect & Interaction 55 Negates targeting effects aimed at Machine monsters you control, but only with Jinzo on the field and only against Machine-targeting effects (verified text; inferred scope).
Material Utility 5 A Spell has no material value and cannot be used as a Link, Synchro, or Xyz material (verified card type).
Resilience & Flexibility 40 Quick-Play activation gives some flexibility, and the indestructibility mode lasts the turn, but both need Jinzo control (verified text; inferred spot-dependence).
Deck-Building Efficiency 55 Average 1.85 copies, with 6 decks running 3, and it sits in the Jinzo shell where its partners are already present (observed deck stats; inferred slot cost).

Calculation

Weight profile: Primary role only (Negation/Interaction); no secondary role blend. Intrinsic ≈ 46, Deck ≈ 46, Meta = provisional. Modifiers: Jinzo-control requirement (-2). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Protects Machine monsters from opponent card effects for a turn while Jinzo is in play
  • Negates targeting effects aimed at your Machine monsters, a narrow but real interaction
  • Quick-Play timing, so it can respond during the opponent's turn
  • Practical in its archetype: 20 recent decks run it, most of them Jinzo

Weaknesses

  • Only works while you control Jinzo
  • Only interacts with Machine-type monsters and Machine-targeting effects
  • No card advantage, search, or board presence
  • Poor as material and does nothing to build a board on its own

Counters / choke points

  • Non-targeting effects, which the negation clause does not cover
  • Removing or banishing Jinzo before activation
  • Opponent effects that do not target Machine monsters

Best use

Negation/Interaction side spell for Jinzo-based decks. Decks: Jinzo. Suggested copies: 2.

Evidence & gaps

  • Verified: Quick-Play Spell with two Jinzo-conditional effects: indestructibility for Machine monsters and negation of Machine-targeting effects (card text); Archetype listed as Jinzo; text requires controlling Jinzo (card text); Appears in 20 recent decks, 13 Jinzo, average 1.85 copies (deck stats)
  • Observed: Top partners Jinzo - Jector and Cyber Energy Shock at 95% co-occurrence (deck stats); Distinct archetypes 7, but mostly Jinzo (deck stats)
  • Inferred: Practical in-archetype role as a Jinzo-protection and negation spell (text plus deck inclusion); Limited use outside Jinzo-based decks (text requires Jinzo control)
  • Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only no banlist token; assumed 3 copies (unlimited)
