Why it scores here

Hunting Horn converts a hand or field Warrior setup into a Fusion Summon from the Extra Deck, and only in the Battle Phase does it add a conditional ATK halving on opponent monsters, capped at the hand materials used. Its real value is the Fusion body it produces, not a board of its own. The 11 attached decks confirm it is a consistent War Rock staple, but that is inclusion, not strength, and the 0 recorded boards mean its conversion rate is unmeasured. The attack lock and the Spell's exposure to interaction keep the score well below what its role would suggest on paper.

Axis scores

Axis Score Evidence
Accessibility 55 A Spell that needs Warrior materials plus an Extra Deck Fusion, and it appears in 11 of the attached decks across 4 archetypes, mainly War Rock (inferred from text; deck inclusion observed).
Combo & Conversion 55 The text yields one Fusion body plus a conditional Battle Phase ATK halving, but there are 0 recorded combo boards to confirm the conversion (inferred from text).
Resource Economy 45 It spends a Spell and hand Warriors to put one Fusion on the board, which is roughly even with no refuel or draw (inferred from text).
Effect & Interaction 40 The ATK halving is soft, Battle Phase only, and capped by materials used, with no negate or removal (inferred from text).
Material Utility 5 It is a Spell card and cannot be used as material, so the axis is near zero (verified from card type).
Resilience & Flexibility 35 A Spell with a one-per-turn limit and a self attack lock, so one negate ends the line, though the lock is only from the text (inferred from text).
Deck-Building Efficiency 60 The card runs 1 to 3 copies with no garnet or lock-in beyond the attack restriction, and it sits with two partners at 100% co-occurrence (observed from decks).

Calculation

Weight profile: 0.7 Starter/Combo enabler + 0.3 Board breaker. Intrinsic ≈ 49, Deck ≈ 53, Meta = provisional. Modifiers: Self attack lock (-3). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Fusion Summon from the Extra Deck in one activation, using hand or field Warriors
  • Conditional Battle Phase ATK halving that scales with materials used from hand
  • Live in 4 archetypes, with War Rock as the main home (6 of 11 decks)
  • Two partners at 100% co-occurrence in the attached decks

Weaknesses

  • Spell card, so it cannot be material and depends on the Battle Phase condition for its board effect
  • Self attack restriction limits the turn it is used
  • Only one copy per turn, and no negate or removal
  • No recorded combo boards, so its conversion rate is unverified

Counters / choke points

  • Spell negation (Ash Blossom & Joyous Spring is a frequent partner in the attached decks, not a confirmed counter in the evidence)

Best use

Fusion starter for Warrior-based Extra Deck lines, with a Battle Phase ATK halving as a secondary effect. Decks: War Rock, Amazoness, Hunting Scout of the Deep Forest. Suggested copies: 2.

Evidence & gaps

  • Verified: Card text: Fusion Summon an EARTH Warrior Fusion from the Extra Deck using hand or field Warriors; Card text: halves ATK only in the Battle Phase, up to the hand materials used; Card text: self attack lock except with EARTH Warrior monsters; Card text: one activation per turn; Card type: Spell, so it cannot be material
  • Observed: 11 attached decks, 6 in War Rock, 3 in Amazoness, 1 each in Exodia and U.A.; Average 2.18 copies per deck, distribution 1 to 3; Faisan and Chevreuil at 100% co-occurrence
  • Inferred: Real Fusion-starter role, although it is not confirmed by combo boards; Vulnerable to Spell negation, given the text and common interaction
  • Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, assumed 3 copies (unlimited) no per-archetype starter count, so DeckResilience relies on the archetype count alone
