Why it scores here

World Legacy Monstrosity is a Quick-Play spell that reliably converts a Level 9 monster into board presence: one mode summons a Level 9 from hand, and the other summons two more Level 9s from the Deck, though those two are temporary and destroyed in the End Phase. It is live in a wide range of hands and runs at 3 copies in 348 of the 400 sampled decks, so access is strong. It earns little for its stats or the card's own body, which is a spell with no material value, no negation, and no card advantage, so its score comes from access and board conversion alone. Deck-level presence is treated as confirmation of a real role, not as a power driver.

Axis scores

Axis Score Evidence
Accessibility 80 Quick-Play, usable on the opponent's turn, needs only a Level 9 monster in hand or on field; 348 of 400 decks run 3 copies (observed, deck evidence).
Combo & Conversion 70 Text says one or two Level 9 bodies per activation, and the Deck-sourced pair is strong board presence, but there are no recorded combo boards to confirm the conversion (inferred, text-only).
Resource Economy 35 No draw, search, or recursion, and summoning from hand is card-neutral; its only benefit is that a second body comes from the Deck (verified, card text).
Effect & Interaction 10 No negation, removal, or hand-trap reach; the card is purely a summoning effect (verified, card text).
Material Utility 15 A spell has no material body of its own; the Level 9 monsters it summons are the material value, not the card itself (verified, card text).
Resilience & Flexibility 45 Quick-Play usable across turns, but it is once per turn, and the second-mode bodies are destroyed in the End Phase and cannot attack (verified, card text).
Deck-Building Efficiency 70 Three copies in the main deck, no garnet or lock restriction, and a usable Level 9 pool in Generaider decks make it cheap to run (observed, deck evidence).

Calculation

Weight profile: 0.7 Starter / Combo enabler + 0.3 Extender. Intrinsic ≈ 58, Deck ≈ 61, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Quick-Play activation on either turn lets it act in response
  • Summons a Level 9 from hand with no card cost, and a second mode adds two Deck-sourced Level 9 bodies
  • Wide practical access: 3 copies in 348 of 400 sampled decks

Weaknesses

  • Zero card advantage: the summons are card-neutral and the Deck bodies are destroyed in the End Phase
  • No interaction: it cannot negate, remove, or disrupt the opponent
  • Needs a Level 9 monster in hand or on field to do anything
  • Once per turn limit

Counters / choke points

  • Negation or hand traps that stop the spell in response
  • Breaking the Level 9 bodies or the Level 9 monster it targets

Best use

Starter / Combo enabler. Decks: Generaider (Level 9 Boss-based decks), Runick (Mysterune), World Legacy. Suggested copies: 3.

Evidence & gaps

  • Verified: Quick-Play spell with two modes: Special Summon a Level 9 from hand, or Special Summon two Level 9s from the Deck, each with different Type and Attribute from the targeted monster, and destroyed in the End Phase; Once per turn restriction on activation
  • Observed: 348 of 400 decks run 3 copies (avg 2.8); Present in 40 distinct archetypes, with Generaider the largest share; Top partners are Generaider bosses and staples such as Ash Blossom & Joyous Spring and Maxx "C"
  • Inferred: Starter-style role: converts one Level 9 into multiple bodies; Generic Level 9 targeting means the card is not tied to one archetype; Quick-Play timing gives it resilience to opponent-turn plays
  • Data gaps: no combos supplied: combo conversion is text-only inference no banlist token: assumed 3 copies (unlimited) no usage statistics (StatisticsCard): inclusion % is inferred from the deck sample only no ruling or interaction evidence supplied
