During the Battle Phase, if a monster(s) is destroyed by battle or card effect: Target 1 "Number" Xyz Monster in your GY; Special Summon from your Extra Deck 1 "Number C" monster with the same Type but 1 Rank higher, and if you do, attach that monster to it as material, then, if you Special Summoned a "Number C" monster with a number between "101" and "107" in its name, you can add 1 "Seventh" or "Barian's" Spell/Trap, or 1 "Rank-Up-Magic" Quick-Play Spell, except "Seventh Force", from your Deck to your hand.

Why it scores here
Seventh Force is a Quick-Play Spell that only acts after a monster is destroyed during the Battle Phase. When it fires, it converts that event into a Special Summon of a Number C from the Extra Deck, plus attaching a Number Xyz from the GY as material, with a conditional search if the summoned Number C is 101-107. It is in all 95 sampled decks, but no combo boards were supplied, so its conversion power rests on text and deck placement alone. The high deck inclusion comes mostly from the Battlin' Boxer shell (about 46 of 95 decks) and does not raise the score. Its body is a spell, so it earns nothing as material.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | In 95 of 95 sampled decks and 71.6% in gameplay type 7, but it needs a Battle Phase destruction and a Number C in the Extra Deck to do anything (observed for presence, inferred for the conditions). |
| Combo & Conversion | 50 | Text-only: one trigger turns a destruction into a Number C plus material attach, with a conditional search, but no combo boards were supplied to confirm the outcome (inferred). |
| Resource Economy | 45 | Spends one card for a Number C body and a conditional search, with no net card-advantage evidence; the GY Xyz attach is repositioning, not card gain (inferred). |
| Effect & Interaction | 15 | No negation or removal; it is a reactive summon engine rather than interaction (verified from text). |
| Material Utility | 0 | A spell, so it cannot be material; scored 0 by the rubric anchor (verified from card type). |
| Resilience & Flexibility | 35 | A Quick-Play that is live only in Battle Phase after a destruction, with a single activation window; its susceptibility to specific negations is not in the evidence (inferred). |
| Deck-Building Efficiency | 55 | Typically one copy per deck (avg 1.34 copies), no garnet, but it hard-restricts the deck to Number C monsters and the Boxer shell (observed copies, inferred restriction). |
Calculation
Weight profile: 0.7 Extender + 0.3 Searcher/Tutor. Intrinsic ≈ 43, Deck ≈ 46, Meta = provisional. Modifiers: self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts a Battle Phase destruction into an Extra Deck Number C summon and material attach
- Appears in every sampled deck (95 of 95) at roughly one copy each, so it is cheap to run
- Conditional search on 101-107 Number C summons adds a second payoff
Weaknesses
- Needs a destruction during the Battle Phase, so it is dead in many turns
- Only works with Number C monsters, which limits it to a narrow archetype core
- No combo evidence supplied, so real board outcomes are unverified
- The Xyz it targets must already be in the GY
Counters / choke points
- Effect negation of the activated Quick-Play Spell (general mechanic; no ruling in evidence, speculation)
- Hand traps that stop the Special Summon or the search (general mechanic; no ruling in evidence, speculation)
Best use
Extender. Decks: Battlin' Boxer. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Battle Phase trigger, Extra Deck Number C summon one rank higher, Xyz attach, conditional search on 101-107; Card type is Quick-Play Spell; Present in 95 of 95 sampled decks; 46 of 95 in Battlin' Boxer homes
- Observed: Average 1.34 copies per deck, 66 of 95 decks at 1 copy; Gameplay type 7 in 68 of 95 decks (71.6%); Partners: Ash Blossom & Joyous Spring 73.7%, Called by the Grave 71.6%, Seventh Ascension 70.5%
- Inferred: Conversion is strong when Boxer's Number C engine is live, but this is inferred from text, not boards; Deck inclusion is driven by the Boxer shell, not intrinsic power; Restriction to Number C and Battle Phase timing lowers accessibility
- Data gaps: no combos supplied, so conversion and starter/material shares are text-only inference no banlist token, so legal copies assumed 3 (unlimited) no rulings supplied for the Quick-Play activation window or negation interactions no average starter count, so DeckResilience is estimated from archetype spread
