Thunder Dragon Fusion — Power Evaluation
Final Score: 57 ± 6 · Confidence: Medium
- Intrinsic: 54 · Deck: 59 · Meta: provisional
- Primary role: Starter / Combo enabler · Secondary: Searcher/Tutor
Why it scores here
Thunder Dragon Fusion converts a Fusion Summon from the Extra Deck into a board, and its Graveyard effect banishes itself to add a Thunder monster from the Deck to hand, so it is a real starter and a conditional tutor. It scores on converting resources into a board and on being cheap to run (one copy in 334 of 400 decks), not on any stats. It has no interaction, cannot be used as material, and its effects are conditional on it being in the Graveyard, so the score stays in the mid-50s.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Live from hand as a Spell with a Graveyard-banish search that needs it to hit the GY first; it is a starter in 2 of 8 recorded boards (observed). |
| Combo & Conversion | 65 | Present in 8 of 8 recorded boards with a board-building Fusion Summon, average power index 29.6 and top examples at 84-86 (observed); the specific Fusion targets are inference from the text. |
| Resource Economy | 60 | Consumes itself to summon a Fusion monster, and can banish from the GY to add a Thunder monster, which nets back a card (inferred from text, with the GY-search reflected in the deck and combo data) . |
| Effect & Interaction | 5 | No negation, removal, or disruption in its text (verified). |
| Material Utility | 5 | A Spell Card that cannot be used as Fusion or Synchro material (verified from frame_type spell). |
| Resilience & Flexibility | 45 | Two once-per-turn effects with a turn-of-GY restriction and a single Spell body that a spell-negating response would stop (inferred); redundancy is only the 1.2 average copies (observed). |
| Deck-Building Efficiency | 80 | Typically one copy in 334 of 400 decks, no garnet or lock restriction in the text, and a 1-copy usage figure in StatisticsCard (observed). |
Calculation
Weight profile: 0.7 Starter / Combo enabler + 0.3 Searcher / Tutor. Intrinsic ≈ 54, Deck ≈ 59, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Fusion Summon engine that reliably puts a Thunder Fusion monster on the field
- Cheap to run as a single copy in most decks
- Graveyard effect recovers a Thunder monster from the Deck to hand
Weaknesses
- Each effect is conditional and once per turn, with the Graveyard-only search not usable on the turn it was sent there
- Contributes no interaction and cannot be used as material
- Its value depends on the Thunder Fusion targets it reaches in the deck
Counters / choke points
- Spell-negating responses to the Fusion activation (inferred from the text, not from deck data)
Best use
Single-copy Fusion Spell starter, with a Graveyard search for a Thunder monster. Decks: Thunder Dragon, Bystial/Byssted, Branded. Suggested copies: 1.
Evidence & gaps
- Verified: Fusion Summon of one Thunder Fusion Monster from the Extra Deck by shuffling materials; Graveyard banish of this card to add one Thunder monster from the Deck, with the 'except the turn sent to the GY' clause; Once-per-turn restriction on each effect; Spell Card frame, so it cannot be Fusion or Synchro material; Present in 400 of 400 sampled decks at an average of 1.2 copies
- Observed: Present in 8 of 8 recorded combos, with 2 as starter and 2 in end hand; Average power index 29.6 and top examples at 84-86; Inclusion of 100% in the Thunder Dragon StatisticsCard rows at typical 1 copy; Frequent partners Thunder Dragon Colossus (98.8%) and Thunder Dragondark (96.2%)
- Inferred: Recovery from the Graveyard search is a net +1 card through the banish-and-add route; Spell-negating responses can interrupt the Fusion activation; The 37 distinct archetypes are a spread of one-deck-type homes, not evidence of universal power
- Data gaps: No banlist token; assumed 3 copies (unlimited) Only 8 recorded combo boards, so combo evidence is thin No rulings data for this card Only 1 of 6 guides has a section featuring the card with a Thunder-specific board, so role context is partly anecdotal
