Block Spider — Power Evaluation

Final Score: 43 ± 10 · Confidence: Low

  • Intrinsic: 43 · Deck: — · Meta: provisional
  • Primary role: Extender · Secondary: Material body

Why it scores here

Block Spider's score comes from what it converts, not its stats: a Level 1 Insect body that, once Special Summoned, can Special Summon another Block Spider from the Deck once per turn, so one summon becomes two bodies. Its DEF 100 and Insect-only attack-target protection earn little, since the protection covers only attacks and only Insect-Type monsters. With no decks, combos or guides supplied, the score is an intrinsic estimate from card text alone, so it stays provisional.

Axis scores

Axis Score Evidence
Accessibility 30 The card has no effect from hand and needs an external Special Summon to start its effect, with no searcher or enabler in the evidence (inference; no combo or deck data).
Combo & Conversion 35 One summon yields a second Block Spider from the Deck, once per turn, so the conversion is one body to two bodies, not a full board (verified from card text).
Resource Economy 45 The Deck-to-field summon adds a body without spending a card from hand, but there is no refuel, search, or card advantage beyond that (verified from card text).
Effect & Interaction 30 The only protection is that Insect-Type monsters cannot be attack-targeted by the opponent, which is narrow and does nothing against non-attack effects (verified from card text).
Material Utility 50 A Level 1 EARTH Insect is a clean generic material for Level 1 summons even when its effect is negated, though its value depends on the Insect and Level 1 requirements of the summon (inferred from card stats and text).
Resilience & Flexibility 30 A DEF 100 body with a once-per-turn summon effect is easy to negate or remove, and the protection effect is also negated along with the card (inferred from card text).
Deck-Building Efficiency 80 Three copies are legal in all four formats, with no garnet, lock, or splash requirement, so redundant copies are cheap to run (verified from card legality data and text).

Calculation

Weight profile: 0.7 Extender + 0.3 Material body. Intrinsic ≈ 43, Deck ≈ —, Meta = provisional. Modifiers: none. Final formula: Intrinsic only (no decks or combos supplied; Deck = null)

Strengths

  • Level 1 Insect body that can convert one Special Summon into a second body from the Deck once per turn
  • Generic Level 1 material that remains usable when its effect is negated
  • Cheap to run: legal in all four formats with no garnet or lock cost

Weaknesses

  • No effect from hand; needs an external Special Summon to start
  • DEF 100 body with no stats or effects that matter in most spots
  • Attack-target protection covers Insect-Type monsters only and only against attacks

Counters / choke points

  • Negating the Special Summon trigger removes the extend effect
  • Attacking or targeting other monsters ignores the Insect-only attack protection
  • Non-attack targeting effects are not blocked by the protection

Best use

Extender (inferred) in Insect or Level 1 Special Summon shells. Suggested copies: 2.

Evidence & gaps

  • Verified: Effect Monster, Level 1, EARTH, Insect, DEF 100, ATK 0, no archetype; Opponent cannot target Insect-Type monsters for attacks, except this card; If Special Summoned, may Special Summon 1 Block Spider from the Deck, once per turn; Legal in TCG, OCG, MasterDuel and DuelLinks

  • Data gaps: no decks supplied, so deck and synergy signals are unavailable no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, so 3 copies assumed no usage statistics (StatisticsCard) available no rulings supplied for the Special Summon trigger timing or the Insect attack protection no inventory of Special Summon sources in the card pool to confirm the start route
