Why it scores here
Rahu Dracotail is a once-per-turn Fusion spell whose value is converting Extra Deck resources into a Dracotail Fusion boss, and the combo evidence confirms it sits on 26 of 26 recorded boards with an average power index of 50.2. It is a single-copy staple (395 of 400 decks run exactly one) and is played across 40 archetypes, which supports a clean, low-cost deckbuilding profile. Its high presence rate in combos reflects its role as a standard fusion step rather than a payoff, and it contributes almost no interaction or material value of its own, so those axes stay low.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 75 | Runs in 400 of 400 sampled decks at 1.02 average copies and co-occurs with the top partners at 96 to 100 percent, though it is a spell that must be drawn or searched (observed, inferred). |
| Combo & Conversion | 74 | Appears on all 26 recorded boards with examples reaching 3 boss monsters and power index 100, but it is a starter on only 3.8 percent of them (observed). |
| Resource Economy | 55 | Fusion spell that consumes materials from hand, deck or field to make one boss; net advantage in the example boards is 5 to 6 but comes mostly from other cards, and it has no recursion of its own (observed, inferred). |
| Effect & Interaction | 15 | No negation, removal or hand-trap effect in its text, and board disruption sub-scores in examples are only 2 to 3 (verified, observed). |
| Material Utility | 5 | A spell card with no body; it is never used as material (verified). |
| Resilience & Flexibility | 30 | Once-per-turn restriction and a spell that interaction can answer; Ash Blossom & Joyous Spring is co-played in 92.8 percent of decks, so disruption is a live risk, with no redundancy inside the card (verified, observed, inferred). |
| Deck-Building Efficiency | 72 | One copy in almost every deck, no garnet or lock beyond a mild extra deck Special Summon restriction after resolving, and played in 40 archetypes (verified, observed). |
Calculation
Weight profile: 0.7 Starter / Combo enabler + 0.3 Extender. Intrinsic ≈ 56.4, Deck ≈ 63.8, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts a Dracotail Extra Deck monster into a boss in a single activation
- Single-copy staple that appears in every sampled Dracotail deck and is played across 40 archetypes
- Appears on all recorded boards, with the top boards reaching 3 bosses
Weaknesses
- No interaction, negation or removal of its own
- Once-per-turn restriction plus a mild restriction on Extra Deck Special Summons for the rest of the turn
- Relies on Dracotail Fusion targets being in the Extra Deck and on drawing or searching the card
- Spell card with no body, so it provides no material value
Counters / choke points
- Spell-negation interaction is common in the same decks (Ash Blossom & Joyous Spring is co-played in 92.8 percent of decks); its effect text is not in the evidence pack

Evidence & gaps
- Verified: Once-per-turn Fusion Summon from the Extra Deck using monsters from hand, deck or field; Restriction on Extra Deck Special Summons (except Fusion) for the rest of the turn; Spell card with no body, so no material value
- Observed: Runs in 400 of 400 sampled decks at 1.02 average copies; Appears on 26 of 26 recorded combo boards with average power index 50.2; Starter on 3.8 percent of boards; no payoff, material or end-board roles; Ash Blossom & Joyous Spring co-played in 92.8 percent of decks; Played across 40 archetypes
- Inferred: Primary role is a Fusion starter rather than a payoff, based on the low starter role share and zero payoff role count; Extender secondary role because it converts Extra Deck resources into board presence; Deck cost is low because a single copy is needed and no garnet is required
- Data gaps: Card role labels in combos are empty, so role shares rely on counts only Only one guide mention, with no direct rulings for interactions No metagame or dated sample of top-cut results
