Ultimate Slayer — Power Evaluation
Final Score: 67 ± 6 · Confidence: Medium
- Intrinsic: 66 · Deck: 68 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Negation/Interaction
Why it scores here
Ultimate Slayer converts an Extra Deck monster it can spare into a targeted return of one opponent Fusion, Synchro, Xyz, Pendulum, or Link monster, which is real interaction against boss bodies. It is protected from monster-effect responses while it resolves, but Spell and Trap responses still work. Its 400-of-400 deck inclusion and 138 archetypes earn the accessibility and deckbuilding scores, while the four recorded boards with no starter, searched, or payoff role keep combo conversion modest. Its high combo power_index (94 average) is not counted as evidence of power, since it comes from boards the card merely appears in, and the 100% inclusion figures in usage_statistics rest on very small per-archetype samples.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 82 | Run in 400 of 400 recent decks at about 2.4 copies each across 138 archetypes, and it is a Spell with no searcher needed beyond a Extra Deck monster to send (observed). |
| Combo & Conversion | 40 | Appears in all 4 recorded combos, but never as starter, searched, material, or payoff, and it does not build a board on its own (observed). |
| Resource Economy | 40 | Costs one Extra Deck monster to the GY for one opponent monster returned to the Extra Deck, a roughly even trade that is tempo rather than card advantage (verified). |
| Effect & Interaction | 70 | Targets opponent Fusion, Synchro, Xyz, Pendulum, or Link monsters and is shielded from monster-effect responses, but cannot touch Effect or Normal monsters (verified). |
| Material Utility | 0 | A Spell card, so it cannot be used as material and provides no body value (verified). |
| Resilience & Flexibility | 60 | Immune to monster-effect responses during activation but still vulnerable to Spell and Trap responses, and it has no recursion (inferred). |
| Deck-Building Efficiency | 75 | Single-copy Spell with no garnet or lock, run at 2 to 3 copies in most lists; the only restriction is needing an Extra Deck monster to send (observed). |
Calculation
Weight profile: Removal / Negation profile; Negation/Interaction secondary maps to the same weight family, so no blend changes the weights. Intrinsic ≈ 66, Deck ≈ 68, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Targeted return of boss-type Extra Deck monsters (Fusion, Synchro, Xyz, Pendulum, Link)
- Shielded from monster-effect responses during activation
- Inclusion across 138 archetypes shows it is a portable staple, not a niche pick
- Cheap to run with no garnet and only a mild Extra Deck requirement
Weaknesses
- Cannot target Effect or Normal monsters
- Needs an Extra Deck monster to send, which costs resources in decks with thin Extra Decks
- Vulnerable to Spell and Trap responses
- Tempo rather than card advantage; the returned monster can be re-summoned
Counters / choke points
- Spell or Trap negation of its activation (inferred)
- Opponent setups that do not rely on Fusion, Synchro, Xyz, Pendulum, or Link monsters (inferred)
Best use
Removal / Negation. Decks: Dogmatika, Mikanko, Branded, Enneacraft, Kaiju, Tri-Brigade.
Evidence & gaps
- Verified: Card text: opponent cannot respond with monster effects to the activation; send 1 Extra Deck monster to GY; target and shuffle 1 opponent Fusion, Synchro, Xyz, Pendulum, or Link monster; Run in 400 of 400 recent decks at an average of 2.39 copies; Cost of sending an Extra Deck monster and the one-for-one tempo exchange
- Observed: Inclusion across 138 distinct archetypes and 9 gameplay-type-independent archetype groups; Appears in all 4 recorded combos, all with role_in_combo empty and no starter, searched, material, or payoff tag; Top partners co-occur in 33% to 56% of decks
- Inferred: Shielded from monster-effect responses but not Spell or Trap responses; The returned monster must be re-summoned, so the tempo gain is real but not card advantage; Removal value is greatest against boss-type Extra Deck monsters
- Data gaps: No banlist token; assumed 3 copies (unlimited) Only 4 recorded combos, so combo role evidence is thin No rulings available Card text is ambiguous on whether 'same card type' refers to the sent monster's type; interpreted as the sent monster's type usage_statistics archetype samples are 1 to 3 decks each, so the 100% inclusion figures are weak
