Why it scores here

Bug Signal is a Quick-Play that Special Summons a Insect monster from the Extra Deck two Ranks higher or lower than an Insect Xyz you control, keeping the Xyz Materials. It converts one live Insect Xyz into a different Xyz, which is a real but conditional extension that needs a Xyz already on the field. The score is held down by the lack of combo data, the absence of card advantage or interaction, and a body that is a Spell and so contributes nothing as material. Its 16-of-16 presence in the sample decks confirms it is practical in Digital Bugs builds, but that frequency is not used to inflate the score.

Axis scores

Axis Score Evidence
Accessibility 55 Needs an Insect Xyz already on the field and is not live from hand alone; it is run in all 16 sample decks at an average of 2.12 copies (observed, deck stats).
Combo & Conversion 55 The rank-shift text reaches a 2-rank-higher or lower Xyz from one activation, but no combo boards were supplied to confirm the conversion (inferred, from card text).
Resource Economy 35 No draw, search, or graveyard refuel; Xyz Materials are kept on the new monster, which conserves material rather than gaining advantage (verified, card text).
Effect & Interaction 10 Summon effect only, with no negation, removal, or disruption (verified, card text).
Material Utility 5 A Spell with no body, so it cannot be used as material; it contributes nothing when blanked (verified, card text).
Resilience & Flexibility 40 Quick-Play and usable on the opponent's turn, but once per turn and dependent on a specific Insect Xyz target (verified, card text).
Deck-Building Efficiency 75 A single Spell with no garnet or brick restriction, legal in TCG, OCG, Master Duel and Duel Links, and run at 1 to 3 copies (verified, decks stats and formats).

Calculation

Weight profile: 0.7 Extender + 0.3 Combo enabler. Intrinsic ≈ 48, Deck ≈ 55, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Rank-shifts an Insect Xyz up or down two Ranks in one activation
  • Keeps Xyz Materials attached to the new monster
  • Quick-Play, so usable on the opponent's turn
  • Clean single-slot Spell with no garnet or lock cost
  • Played in all 16 sample decks across five archetype homes

Weaknesses

  • Needs an Insect Xyz on the field before it does anything
  • Once per turn
  • No card advantage, search, or refuel
  • No negation or removal
  • Contributes no material body

Counters / choke points

  • Opponent Spell negation in response to the activation (inferred)
  • Removing or bouncing the targeted Insect Xyz in response (inferred)

Best use

Xyz rank-shift extender. Decks: Digital Bugs.

Evidence & gaps

  • Verified: Card text: Special Summon from Extra Deck an Insect monster 2 Ranks higher or lower, using the targeted Insect Xyz as material; Card text: once per turn, Quick-Play Spell; Run in 16 of 16 sample decks, average 2.12 copies
  • Observed: Partners with Digital Bug support cards in 100% of sample decks
  • Inferred: Conversion depends on the Insect Xyz target being present; Likely answered by Spell negation or removal of the target
  • Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is from the deck sample only
