Zombie World — Power Evaluation
Final Score: 48 ± 8 · Confidence: Medium
- Intrinsic: 47.4 · Deck: 48.4 · Meta: provisional
- Primary role: Floodgate/Control · Secondary: Utility
Why it scores here
Zombie World is a Field Spell that does its work through its text: it turns every monster on the field and in both graveyards into a Zombie, and it stops both players from Tribute Summoning anything that is not a Zombie. That is a real but narrow floodgate, and it converts boards mainly by enabling Zombie-type recursion rather than by building one. Its high deck count and the 100 power_index on the combo boards it appears in do not earn points, because the sample only shows that it is included, not that it is strong (Guardrail 3). The combo rows carry no role tags, so the Floodgate role rests on the card text alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | No searcher or access route appears in the evidence, but the card is in all 400 sampled decks at 1 to 3 copies, so it is reliably available as a single Field Spell (observed, inferred). |
| Combo & Conversion | 30 | It is present in all 4 recorded combos but has no role tag, and it builds no board by itself; its value comes from the Zombie conversion of monsters already in play (inferred). |
| Resource Economy | 30 | No draw, search, or GY-banish refuel is in the text or the combo stats, and it costs one card for one effect, so the economy is roughly even (verified). |
| Effect & Interaction | 55 | The Tribute Summon lock on both players is a soft floodgate; it hurts Tribute-based lines but does not stop Special Summons (verified, inferred). |
| Material Utility | 10 | It is a Spell Card, so it provides no level, attribute, or material body and scores low on this axis (verified). |
| Resilience & Flexibility | 35 | It is a single face-up Field Spell with no redundancy and is removable by any field-destruction effect; it survives only where the field is not contested (inferred). |
| Deck-Building Efficiency | 55 | It is a single-copy Field Spell with no garnet or brick cost, but its Tribute lock restricts the deck's own non-Zombie Tribute monsters, so it is only moderately clean to run (verified, inferred). |
Calculation
Weight profile: Floodgate/Control primary, no secondary blend (Utility secondary not applied to weights). Intrinsic ≈ 47.4, Deck ≈ 48.4, Meta = provisional. Modifiers: self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Strong floodgate against Tribute Summon lines (the lock applies to both players)
- Single-copy, low-cost Field Spell with no garnet or brick requirement
- Converts monsters in both fields and graveyards into Zombies, supporting Zombie-type recursion
Weaknesses
- Provides no card advantage, search, or refuel
- Has no body and no material value
- Single face-up Field Spell that a single field-removal effect can answer
- Its Tribute lock hurts the deck's own non-Zombie Tribute monsters
Counters / choke points
- Field-destruction effects that remove the Field Spell
- Non-Tribute Summon strategies that ignore the lock
- Turn-one or non-field Zombie-independent lines
Best use
Floodgate/Control: Tribute Summon lock, with Zombie conversion for recursion lines. Decks: Zombies, Eldlich, Vampires, Mayakashi. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: all monsters on field and GY become Zombie; neither player can Tribute Summon non-Zombie monsters; Spell Card, Field race, no ATK/DEF or link; Copies per deck avg 1.48, max 3; usage_statistics: 100% inclusion in 4 archetypes at 1 to 3 typical copies
- Observed: Present in 400 of 400 sampled decks; Present in 4 of 4 recorded combos, with no role tags; Top partners: Necroworld Banshee (63.5%), Doomking Balerdroch (61.2%); Not a top card (is_top_card false)
- Inferred: Floodgate/Control is the primary role, from text and the Tribute lock; Zombie conversion supports Zombie recursion lines; Accessibility is reliable because the card is included at 1 copy in every sampled deck
- Data gaps: decks_evidence covers only decks that contain the card (400 of 400), so inclusion percentages are conditional and cannot measure how often it is played across the meta combos_evidence has 4 combos with no role_in_combo tags, so no starter, searcher, or payoff role is corroborated No searcher or access route is in the evidence No metagame or dated ranking sample; meta_power is null No rulings or ruling notes for Zombie World's interaction with Tribute-based monsters
