Target 1 face-up monster on the field and 1 "Elemental HERO" monster in your GY; that target on the field gains ATK equal to the other target's ATK (until the end of this turn), then if you have an "Elemental HERO" Normal Monster in your field or GY (except during the Damage Step), you can Fusion Summon 1 "Elemental HERO" Fusion Monster from your Extra Deck, by banishing its materials from your GY. You can only activate 1 "Soul Union" per turn.
Soul Union — Power Evaluation
Final Score: 49 ± 6 · Confidence: Medium
- Intrinsic: 49 · Deck: 48 · Meta: provisional
- Primary role: Combo enabler · Secondary: Extender
Why it scores here
Soul Union is a Normal Trap whose value is converting Elemental HERO graveyard resources into a Fusion Summon from the Extra Deck and a temporary ATK boost on a field monster. Its score comes from being live in 9 of 9 sampled HERO decks with a single-copy slot cost, but it is tied to the Elemental HERO archetype, requires an EHERO Normal Monster in the field or graveyard, and cannot act in the Damage Step. The card has no interaction value and cannot serve as material, so the high deck inclusion and Fusion-enabler role are what lift it, not any intrinsic strength. No combo data was supplied, so combo conversion rests on text and partner evidence.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Present in 9 of 9 sampled decks (7 of 9 in Heroic gameplay) alongside Neos and Polymerization, but it is a set Trap with no searcher text and no combo appearances recorded (observed; route inferred from text). |
| Combo & Conversion | 60 | Text gives a Fusion Summon from the Extra Deck plus an ATK gain, which can reach a full board when the EHERO Normal Monster condition is met; no recorded combo boards exist to confirm it (inferred from text). |
| Resource Economy | 55 | Converts graveyard materials into a Fusion monster by banishing them, a real but one-sided refuel with no draw or recovery (verified from text, partly inferred). |
| Effect & Interaction | 5 | No opponent-facing negation, removal, or disruption; its ATK gain only affects the controller's own monster (verified from text). |
| Material Utility | 5 | A Trap card cannot be used as Fusion, Synchro, or Xyz material, so the body contributes nothing when blanked or in play (verified from text). |
| Resilience & Flexibility | 40 | Requires a set Trap and an EHERO Normal Monster in field or graveyard, is limited to one activation per turn, and cannot resolve its Fusion during the Damage Step (verified from text; resistance to interaction inferred). |
| Deck-Building Efficiency | 70 | One slot at 1 copy in 8 of 9 decks with no garnet or lock beyond the archetype dependence, so it is cheap to run in its home deck (observed from deck copies). |
Calculation
Weight profile: 0.7 Combo enabler + 0.3 Extender. Intrinsic ≈ 49, Deck ≈ 48, Meta = provisional. Modifiers: Archetype-locked restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts EHERO graveyard cards into a Fusion Summon from the Extra Deck, a 0-cost body from the GY
- Included in 9 of 9 sampled HERO decks alongside Neos, Polymerization, and Miracle Fusion (observed)
- Single-copy slot cost with no garnet or lock (observed)
Weaknesses
- Set Trap that must survive the opponent's turn before activating, and no direct interaction (inferred)
- Restricted to the Elemental HERO archetype and needs an EHERO Normal Monster present (verified from text)
- Cannot be used as material and cannot resolve its Fusion during the Damage Step (verified from text)
- No combo evidence supplied, so its real conversion rate is unmeasured (data gap)
Counters / choke points
- Opponent negation or destruction of the set Trap before it is activated (inferred)
- Opponent removal or disruption of the EHERO graveyard targets that the effect needs (inferred)
Best use
Fusion enabler that converts graveyard EHERO resources into an Extra Deck Fusion Summon. Decks: Elemental HERO Heroic builds with Neos, Polymerization, and Miracle Fusion. Suggested copies: 1.
Evidence & gaps
- Verified: Trap Card, Normal race, formats TCG/OCG/DuelLinks; Effect requires a EHERO Normal Monster in field or GY and banishes Fusion materials from GY; Once per turn, no activation during the Damage Step
- Observed: In 9 of 9 sampled decks, 1 copy in 8 and 2 copies in 1; Heroic gameplay type in 7 of 9 decks, partners at 100% co-occurrence for Neos and Polymerization
- Inferred: Set Trap vulnerability before activation; Archetype dependence limits portability to the EHERO family; Combo conversion rated from text since no board data exists
- 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 no Limited/Forbidden banlist status provided for the card
