Stronghold Guardian — Power Evaluation

Final Score: 41 ± 8 · Confidence: Medium

  • Intrinsic: 42 · Deck: 41 · Meta: provisional
  • Primary role: Hand trap

Why it scores here

Stronghold Guardian is a hand-only, defensive trick: it costs itself to give one attacked Defense Position monster +1500 DEF for the turn, which only matters during a battle against a DEF monster. The evidence shows it is a real tech choice in 18 recent decks, mostly alongside defensive partners such as Stone Statue of the Aztecs, Mirror Wall and Wall of Disruption, but there are no combos, so its conversion score stays low. Its 0 ATK, 1500 DEF stats earned nothing; the score comes from the narrow but reliable protection it offers when the right situation arises.

Axis scores

Axis Score Evidence
Accessibility 45 Live from hand whenever a DEF-position monster is attacked, and it is played in 18 of 18 sampled decks with an average of 2.11 copies, but it needs that specific board state (observed).
Combo & Conversion 10 No combo boards in the evidence (appearances 0); it only prevents a battle loss and does not build a board (verified from text, inferred from absence of combo data).
Resource Economy 25 Costs itself to protect one monster with no draw or recovery, so it is a one-for-one defensive trade at best (verified from text).
Effect & Interaction 40 Blanks a battle-based loss in the Damage Step, but only against attacks on DEF monsters, so its reach is narrow (verified from text, inferred for the practical reach).
Material Utility 15 A 4-Level 0-ATK Warrior that is sent to the GY from hand, so it is rarely on the field to act as material (inferred from text).
Resilience & Flexibility 35 The effect works from hand during the Damage Step, a window few interaction cards cover, but it depends on a DEF-position monster being attacked (inferred from text).
Deck-Building Efficiency 55 Max 3 copies, no garnet or lock, and it is a single tech slot in DEF-focused lists; the cost is that it is dead in decks without DEF monsters (observed from deck counts and partners).

Calculation

Weight profile: Hand trap primary, no secondary role. Intrinsic ≈ 42, Deck ≈ 41, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Cheap, hand-only protection for a DEF monster during the Damage Step
  • Appears in 18 of 18 sampled decks, 3 copies in 10 of them, across 9 archetypes
  • Consistently paired with defensive support cards

Weaknesses

  • Only useful when a Defense Position monster is attacked
  • Zero combo conversion in the evidence
  • Dead in decks with no DEF-position monsters
  • Sends itself to the GY with no card advantage

Counters / choke points

  • Decks that avoid attacking DEF-position monsters or that use attacks that bypass the DEF-position condition

Best use

Defensive hand trap that keeps a DEF-position monster alive through a battle. Decks: DEF-focused Guardian and Destiny HERO lists with Stone Statue of the Aztecs, Mirror Wall or Wall of Disruption.

Evidence & gaps

  • Verified: Hand-only effect: send from hand to GY during the Damage Step after a DEF-position monster you control is attacked; Effect grants the attacked monster +1500 DEF until the End Phase; Frame: Level 4 EARTH Warrior Effect Monster, 0 ATK, 1500 DEF; Average 2.11 copies per deck, 3 copies in 10 of 18 decks
  • Observed: Present in 18 of the recent sampled decks, across 9 archetypes; 16 of 18 decks in gameplay type 4 (88.9%); Top partners (Stone Statue of the Aztecs, Destiny HERO - Defender, Mirror Wall, D2 Shield and others) appear in 50-56% of its decks; No combo boards recorded (appearances 0)
  • Inferred: Its practical value depends on the opponent attacking a DEF-position monster, so it is a situational defensive tool; Low score despite 9 archetypes reflects narrow function, not broad versatility; Combo conversion is near zero because it is a defensive reaction, not a board builder
  • Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, assumed 3 copies no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only no evidence of how often the effect actually triggers in live matches
