Galactic Spiral Dragon — Power Evaluation
Final Score: 58 ± 6 · Confidence: Medium
- Intrinsic: 54 · Deck: 61 · Meta: provisional
- Primary role: Combo enabler · Secondary: Material body
Why it scores here
The card's value is its Main Phase effect, which sets every monster you control to Level 8, plus a hand/GY Special Summon (Defense Position, banished when it leaves the field) that needs two LIGHT/DARK Dragons. It turns a Dragon-heavy board into Level 8 material for Tachyon-style lines, and it is in all 400 sampled decks. Its 2500 ATK/DEF earns nothing, and the score stays moderate because it has no draw, refuel, or interaction, and the combo sample is thin (3 boards, 0 as starter).
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 62 | Hand/GY Special Summon behind a two-Dragon condition, present in 400/400 sampled decks but never a starter in combos (observed + inferred from text). |
| Combo & Conversion | 48 | Level-8 setup enables Tachyon lines, but only 3 recorded boards, with 1 as material and an average power index of 56.3 (observed; the rest is inferred). |
| Resource Economy | 30 | No draw, search, or GY refuel; the hand/GY summon is a 1-for-1 body that is banished on leaving (verified from text). |
| Effect & Interaction | 5 | No negation, removal, or hand trap (verified from text). |
| Material Utility | 62 | Native Level 8 Dark Dragon, used as material in 33% of boards; the Level-setting effect still works as a material-side tool (verified + observed). |
| Resilience & Flexibility | 45 | Two once-per-turn effects across hand and GY, but no protection once negated and the summon is banished on leaving (inferred from text). |
| Deck-Building Efficiency | 62 | Typically 1 copy per deck, no garnet or brick. The surrounding Dragon deck carries a self-lock risk from the guides, not this card (observed + inferred). |

- Data gaps: no banlist token — assumed 3 copies (unlimited) only 3 combos recorded; combo conversion is thin no rulings beyond the card text
