Hieracosphinx — Power Evaluation

Final Score: 43 ± 8 · Confidence: Medium

  • Intrinsic: 44 · Deck: 42 · Meta: provisional
  • Primary role: Utility · Secondary: Material body

Why it scores here

Hieracosphinx scores mainly as a generic Level 6 Rock body. Its 2400 ATK and Level 6 stats earn nothing by themselves, and its only effect is a narrow restriction that stops the opponent from attacking face-down Defense Position monsters. Deck spread across 4 archetypes and 1-copy usage supports a modest score, but the sample is small (7 decks) and there is no combo or searcher evidence, so combo conversion is text-only.

Axis scores

Axis Score Evidence
Accessibility 40 Live as a Level 6 monster in hand, but no searcher or starter route appears in the evidence (no combo data) (inferred).
Combo & Conversion 20 Does nothing on its own beyond being a body; no recorded combo boards exist, so the score rests on text alone (inferred).
Resource Economy 10 No card advantage, search, or recursion in the effect text (verified).
Effect & Interaction 30 The effect only blocks attacks on face-down DEF monsters, which is narrow and situational (verified).
Material Utility 55 Plain Earth Rock Level 6 body, a generic material; its body value does not depend on the effect (inferred).
Resilience & Flexibility 30 Nothing supports multi-zone or multi-turn value; the effect needs a face-down DEF monster on the field (verified).
Deck-Building Efficiency 65 Runs 1-of in 6 of 7 sampled decks with no garnet or lock; cheap to run (observed).

Calculation

Weight profile: 0.7 Utility + 0.3 Material body. Intrinsic ≈ 44, Deck ≈ 42, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Level 6 Rock body is a usable generic material
  • Appears in 7 sampled decks across 4 archetypes, usually 1 copy
  • Cheap to run: 1-of, no garnet or lock

Weaknesses

  • Effect only protects face-down DEF monsters from attack; narrow and situational
  • No combo or searcher evidence; does nothing alone
  • No recovery, card advantage, or interaction beyond the one restriction

Counters / choke points

  • Effects that remove or destroy without attacking are unaffected by the restriction (inferred from text)
  • Face-up or non-DEF monsters are never protected by the effect (verified from text)

Best use

Level 6 material body with a defensive side effect. Decks: Guardian Sphinx / Criosphinx Sphinx-leaning decks, Mimighoul, Greed, and Hole decks. Suggested copies: 1.

Evidence & gaps

  • Verified: Effect text: opponent cannot select a face-down DEF monster as an attack target; Level 6 Earth Rock, ATK 2400 / DEF 1200; Formats: TCG, OCG, MasterDuel, DuelLinks
  • Observed: Appears in 7 sampled decks; 6 run 1 copy, 1 runs 2 (avg 1.14); Guardian Sphinx co-occurs in 85.7% of decks; 0 recorded combo boards contain the card
  • Inferred: Usable as a generic Level 6 Rock material body; Effect-negation would not remove its body value
  • 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 only 7 decks in the sample — thin deck evidence no rulings supplied
