Spirit Illusion — Power Evaluation
Final Score: 52 ± 6 · Confidence: Medium
- Intrinsic: 52 · Deck: 51 · Meta: provisional
- Primary role: Combo enabler · Secondary: Board breaker
Why it scores here
Spirit Illusion's score comes from its text, not its stats: it is a Spell that needs a Level 5+ Fiend or Zombie to equip, and then either Fusion Summons one Fusion Monster from the Extra Deck or makes a Level 5 Doppelganger Token, once per turn. Its ATK-reduction on attacks is situational and requires an attack involving the equipped monster. The 67-deck sample (22 archetypes, 1.45 copies average, strong co-occurrence with Super Polymerization and Forbidden Droplet) confirms it is a real, portable piece, but that frequency only moves accessibility and deck fit, not the intrinsic score. There are no combo boards, so conversion is inferred from text alone and the score stays in the middle.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs a Fiend or Zombie of Level 5 or higher on the field to equip, but it appears in 67 recent decks across 22 archetypes at 1.45 copies average (observed, text-gated). |
| Combo & Conversion | 60 | Fusion Summon from the Extra Deck or a Level 5 Doppelganger Token is a real one-card body gain, but there are no recorded combo boards to confirm a full board (inferred). |
| Resource Economy | 40 | The Fusion Summon and token are card-neutral bodies with no draw, search, or recursion, so advantage stays roughly even (verified from card text). |
| Effect & Interaction | 45 | The ATK reduction is limited to attacks involving the equipped monster and does not stop the opponent's effects (verified from card text). |
| Material Utility | 30 | The Spell is not a material, and the equipped monster's fit as material depends on a Fiend/Zombie gate; the Doppelganger token is a Level 5 body with the copied Type and Attribute (inferred). |
| Resilience & Flexibility | 35 | A face-up Equip Spell is exposed to backrow destruction and the equipped monster's removal, and it does nothing once that monster is gone (inferred). |
| Deck-Building Efficiency | 60 | One copy in most decks with a mild Fiend/Zombie restriction; the card is otherwise clean to run and splashable (observed, 1.45 copies average). |
Calculation
