Once per turn, you can equip this card to a "Soitsu" you control, OR unequip it to Special Summon this card in face-up Attack Position. When equipped to a monster by this card's effect, that monster gains 2500 ATK. (A monster can only be equipped with 1 Union Monster at a time. If the equipped monster would be destroyed by battle, destroy this card instead.)
Doitsu — Power Evaluation
Final Score: 38 ± 8 · Confidence: Medium
- Intrinsic: 38 · Deck: 38 · Meta: provisional
- Primary role: Utility · Secondary: Material body
Why it scores here
Doitsu's text converts into one thing: +2500 ATK on a Soitsu, plus a once-per-turn unequip-to-Special-Summon of itself. It has no search, no card advantage and no interaction, and its effect depends on a Soitsu already being on the field, so the 100 ATK body and the high ATK boost earn little. The score sits in the low 40s because the card is a niche Union piece with two sampled decks and no combo evidence, not because of any stat.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 30 | Level 4 can be Normal Summoned, but its effect needs a Soitsu on the field and no searcher is evidenced; only 2 sampled decks (verified/observed) |
| Combo & Conversion | 35 | The +2500 ATK equip converts a Soitsu into a large attacker, but there are zero recorded boards to confirm it (inferred) |
| Resource Economy | 20 | No draw, search, or GY refuel; the unequip-to-Special-Summon is a reposition, not advantage (verified) |
| Effect & Interaction | 10 | No negation, removal or hand-trap effect in the text (verified) |
| Material Utility | 40 | Level 4 Fairy body is a usable material, but no material role evidence and the Union restriction limits its value (inferred) |
| Resilience & Flexibility | 30 | Once-per-turn and tied to a Soitsu or its own equipped state, so one interruption ends the line (inferred) |
| Deck-Building Efficiency | 50 | Single-copy Union body run as 2 copies across two decks; needs the Soitsu trio for value, a mild restriction (observed) |
Calculation
Weight profile: Utility / no clear role (default), no secondary blend. Intrinsic ≈ 38, Deck ≈ 38, Meta = provisional. Modifiers: Union self-restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Large +2500 ATK boost on an equipped Soitsu
- Once-per-turn self-Special-Summon from the equipped state gives some reuse
- Level 4 Fairy body is a usable material
Weaknesses
- No search, draw or recursion beyond a single self-revive
- Its value depends entirely on a Soitsu being on the field
- Single-card effect with no interaction and no protection
Counters / choke points
- Any negation or destruction of the equipped Soitsu ends the boost
- Monster removal that hits the Union body before it is equipped
Best use
Utility Union body / equip-based attacker. Decks: Union-focused Soitsu line (Soitsu/Aitsu/Koitsu partners).
Evidence & gaps
- Verified: Effect text: once-per-turn equip to a Soitsu or unequip to Special Summon in face-up Attack Position, +2500 ATK when equipped; Level 4, 100 ATK / 200 DEF Union Effect Monster; Appears in 2 of 400 sampled decks as 2 copies each
- Observed: Two sampled decks, both gameplay type 6, 100% co-deck with Soitsu, Aitsu, Koitsu
- Inferred: Effect requires a Soitsu on the field to be useful; Limited accessibility without a searcher, since none is evidenced
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
