Junk Changer — Power Evaluation
Final Score: 56 ± 8 · Confidence: Medium
- Intrinsic: 54 · Deck: 57 · Meta: provisional
- Primary role: Combo enabler · Secondary: Material body
Why it scores here
Junk Changer is a Level 3 Tuner whose only effect, once per turn on Normal or Special Summon, changes the Level of one Junk monster by 1. Its value is as a Level adjuster for Junk and Synchro routes, which the 37-deck sample supports through heavy co-occurrence with Junk Synchron (97.3%) and Junk Warrior (70.3%). The score is held back because the effect is narrow and gives no card advantage or interaction, and no combo boards were supplied to show how far it converts. High deck counts were treated as confirmation of accessibility and deck fit, not as proof of raw power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Level 3 Tuner with no searcher in the text, so it must be drawn or searched by other cards; 37 of the sampled decks run it, mostly in Synchron and Junk shells (observed, inferred for the route). |
| Combo & Conversion | 45 | The effect changes the Level of a Junk target by 1, which enables Junk and Synchro level matches but adds no body or board by itself; no combo examples were supplied (inferred from text, observed for deck co-occurrence). |
| Resource Economy | 25 | No draw, search, banish refuel, or recursion in the text, so it is a 1-for-0 body at best (verified from text). |
| Effect & Interaction | 5 | No negation, removal, or hand-trap reach; the only effect is a Level change (verified from text). |
| Material Utility | 65 | A clean generic Level 3 Tuner (Warrior, Earth) that remains usable as a Tuner even when its effect is negated (verified from text, inferred for the negated case). |
| Resilience & Flexibility | 40 | The Level effect is once per turn and needs a live Junk target, so it is fragile, but the Tuner body survives interaction (inferred from text). |
| Deck-Building Efficiency | 80 | A single generic card with no garnet or lock; the average of 1.76 copies per deck shows it is cheap to run (observed from deck evidence). |
Calculation
Weight profile: 0.7 Combo enabler + 0.3 Material body. Intrinsic ≈ 54, Deck ≈ 57, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Generic Level 3 Tuner that can be run in several Synchro and Junk shells
- Cheap to run at 1 to 3 copies with no garnet or lock
- Stays a usable Tuner body when its effect is negated
Weaknesses
- The effect is once per turn and needs a live Junk monster on the field
- No card advantage, search, or interaction
- Converts only into Junk and Synchro level matches, with no measured board conversion
Counters / choke points
- Any negation or the opponent's summon-response effects can shut off the once-per-turn Level change
- Lack of Junk targets on the field leaves the effect dead

- Inferred: Its value comes from Level matching for Junk and Synchro routes; Its Tuner body remains usable when the effect is negated; The card is not a searcher, so it needs to be drawn or searched by other cards
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, so 3 copies (unlimited) was assumed no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only no rulings supplied
