Zodiac Sign

  • Archetype:
  • Zoodiac

  • View:
  • 611




All "Zoodiac" monsters you control gain 300 ATK and DEF. Monsters your opponent controls cannot target face-up Beast-Warrior-Type monsters you control for attacks, except the Beast-Warrior-Type monster you control with the highest ATK (either, if tied). Once per turn, if a "Zoodiac" monster(s) you control would be destroyed by card effect, you can destroy 1 monster in your hand or field instead of 1 "Zoodiac" monster.

Why it scores here

Zodiac Sign converts into little on its own: it adds 300 ATK/DEF to Zoodiac monsters and blocks opponent attacks on Beast-Warriors, but it creates no bodies, no cards, and no advantage, and it has no searcher evidence in the pack. Its score comes mainly from the once-per-turn destruction replacement and the partial attack-targeting protection, which keep a Zoodiac board alive, plus its presence in 32 recent decks across 13 archetypes. The high ATK/DEF boost earns almost nothing on its own, and the four sampled boards record zero starter, searched, or payoff roles, so the combo sample does not confirm its role.

Axis scores

Axis Score Evidence
Accessibility 55 One copy-count sample of 32 decks (avg 2.19, max 3) shows it is consistently playable, but no searcher or starter route is evidenced (observed, 0 starter role / searched-for role).
Combo & Conversion 35 It appears in all 4 recorded boards with an average power index of 91.2, but the role counts are all zero and it builds no bodies itself (observed, inferred for the buff's contribution).
Resource Economy 30 No card advantage or refuel; the destruction replacement swaps one card for another rather than gaining value (verified from text).
Effect & Interaction 45 Blocks opponent monsters from targeting face-up Beast-Warriors for attacks, except the highest-ATK one; it does not stop spell or trap effects (verified from text).
Material Utility 5 A Field Spell with no monster body, so it cannot be used as material and provides no level, attribute, or name (verified from text).
Resilience & Flexibility 55 The once-per-turn destruction replacement protects Zoodiac monsters, and the Beast-Warrior targeting protection adds a second layer; both are limited to Zoodiac and to one use per turn (verified from text, inferred for the survival value).
Deck-Building Efficiency 60 Runs as a single slot at 2.19 average copies, is not a garnet or brick, and is used across 13 archetypes, though most of its decks are Zoodiac (observed, 32-deck sample).

Calculation

Weight profile: 0.7 Utility + 0.3 Floodgate/Control. Intrinsic ≈ 45.6, Deck ≈ 50.1, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Consistent 2–3 copy inclusion in a 32-deck Zoodiac-centred sample (observed)
  • Once-per-turn destruction replacement protects Zoodiac monsters from card effects (verified)
  • Blocks opponent attacks that target face-up Beast-Warriors, except the highest-ATK one (verified)
  • Low deckbuilding cost: one field-spell slot, no garnet or brick restriction (inferred)

Weaknesses

  • Adds no bodies, cards, or card advantage (verified)
  • The ATK/DEF buff does not earn points under the rubric's guardrails (inferred)
  • Protection is limited to attacks and Beast-Warrior-type monsters, so it does not stop spell or trap effects (verified)
  • No searcher or starter route appears in the evidence (observed)

Counters / choke points

  • Opponent effects that destroy or remove the Field Spell itself (inferred from text: the card's protections depend on it staying on the field)
  • Non-attack targeting or effects that bypass the attack-only restriction (inferred from text)
  • Removing the Zoodiac monsters that the replacement protects reduces its value (inferred)

Best use

Field-spell support for the Zoodiac archetype. Decks: Zoodiac. Suggested copies: 2.

Evidence & gaps

  • Verified: Field Spell: all Zoodiac monsters gain 300 ATK/DEF; Opponent monsters cannot target face-up Beast-Warrior-type monsters for attacks, except the highest-ATK one; Once per turn, destruction by card effect of a Zoodiac monster can be replaced by destroying 1 monster in hand or field; Blocks attack-targeting only; no protection against spell or trap effects
  • Observed: Present in 32 of 32 sampled decks, avg 2.19 copies, max 3; Partners are almost entirely Zoodiac monsters (about 94% co-occurrence); Present in 4 of 4 recorded combo boards, avg power index 91.2, with zero starter/searched/material/payoff counts
  • Inferred: Protection value depends on Zoodiac monsters being on the field; Null role data means the combo sample does not confirm a role; Score capped on generic utility because the text is archetype-locked
  • Data gaps: no guides supplied no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion % is inferred from the deck sample only combo role fields (starter role, searched-for role, material role, payoff role) all zero, so role is inferred from text combo sample is only 4 boards
