Junk Box — Power Evaluation
Final Score: 46 ± 6 · Confidence: Medium
- Intrinsic: 44 · Deck: 51 · Meta: provisional
- Primary role: Recovery / Recursion · Secondary: Extender
Why it scores here
Junk Box reliably converts a Level 4 or lower Morphtronic body in the Graveyard into a one-turn board presence, and the End Phase destruction returns that body to the Graveyard for reuse. Its value depends on Morphtronic being present, and it ends up as a short-lived body rather than a card-advantage engine. Its high deck count (135 decks, with 97% co-occurrence with Morphtronic Celfon) confirms it is a real, practical role in its home, not that it is strong in isolation; the 1500-to-5000-ATK question does not enter into it.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs a Level 4 or lower Morphtronic in the Graveyard, which the 135-deck usage and Morphtronic partner list support as a live route (observed). |
| Combo & Conversion | 40 | Produces a single temporary body from the Graveyard and nothing more; there are no recorded combo boards, so conversion is text-only inference. |
| Resource Economy | 55 | Spends no cost and recurs a body already in the Graveyard, but adds no card advantage beyond that body (inferred from text, partly observed through deck usage). |
| Effect & Interaction | 5 | The card has no negation, removal or hand-trap function and no opponent interaction (verified from card text). |
| Material Utility | 8 | A Spell card is not material, so this axis reflects only the indirect role of the body it summons, which is minimal (inferred). |
| Resilience & Flexibility | 35 | A Spell is exposed to spell negation and the card has a single function, though 2 to 3 copies per deck add some redundancy (inferred, partly observed). |
| Deck-Building Efficiency | 55 | Runs 2 copies on average at 3 unlimited, with no garnet or lock, but it is tied to the Morphtronic theme (observed, inferred). |
Calculation
Weight profile: 0.7 Recovery/Recursion + 0.3 Extender. Intrinsic ≈ 44, Deck ≈ 51, Meta = provisional. Modifiers: Archetype-restricted target (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Recurs a Graveyard body to the field with no cost (verified)
- Live in 135 recent decks, with consistent Morphtronic partners (observed)
- Clean, unambiguous text with no once-per-turn or timing traps (verified)
- Cheap to run at 2 copies in a deck (observed)
Weaknesses
- Restricted to Morphtronic Level 4 or lower monsters in the Graveyard (verified)
- No interaction or negation of any kind (verified)
- Temporary body only; it is destroyed in the End Phase, so it adds no lasting board (verified)
- Vulnerable as a Spell to spell negation (inferred)
Counters / choke points
- Spell negation on the activation (inferred; no counter data supplied)
Best use
Graveyard recursion for Morphtronic, using the body as a temporary extender. Decks: Morphtronic (archetype 830), Morphtronic (archetype 1265), Cyber Dragon (archetype 716), Synchron (archetype 718). Suggested copies: 2.
Evidence & gaps
- Verified: Spell that Special Summons one Level 4 or lower Morphtronic from the Graveyard; Destroyed during the End Phase; No interaction or negation effect; 135 decks, 2.09 average copies, up to 3
- Observed: 97% co-occurrence with Morphtronic Celfon; Usage across 19 archetypes, concentrated in Morphtronic; Inclusion of 100% in the Morphtronic usage statistic at 3 copies
- Inferred: Recursion role from text; Vulnerable to spell negation; Two copies is the typical deck count for a Morphtronic build
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no counter or banlist data beyond the assumed 3 copies
