Why it scores here
Double Interlock is a Spell whose two effects convert monsters already in the Graveyard into a Fusion or Ritual Summon, each gated by a Rokket monster and each once per turn. It appears in all 400 sampled decks, almost always as a single copy, and co-occurs with the Rokket and Dragon Link core, so its accessibility and deck-cost scores are high. The score is held back by the lack of card advantage, the absence of any interaction, and a single recorded combo as the only structural sample. High deck inclusion confirms the card is played, not that it is intrinsically strong, so the deck-level weight does not lift it further.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 80 | Present in 400 of 400 decks at an average of 1.02 copies, but both effects require a Rokket monster in the Graveyard, which caps it below a free-roll card (observed; the Rokket condition is verified from text). |
| Combo & Conversion | 72 | The one recorded combo reaches a full board with power index 100, but a single sample and zero recorded starter or material roles keep this below the top band (observed, thin sample). |
| Resource Economy | 55 | No draw, search, or refuel; it spends one Spell to turn Graveyard monsters into a summon, which is roughly even rather than card advantage (verified from text, inferred for net value). |
| Effect & Interaction | 5 | No negation, removal, or hand-trap effect in its text (verified). |
| Material Utility | 15 | A Spell with no body, so it contributes nothing as material on its own (verified from frame type). |
| Resilience & Flexibility | 50 | Two independent routes (Fusion and Ritual) give some redundancy across spots, but it is a single card that is vulnerable to spell-level interaction and is once-per-turn per effect (verified text, inferred exposure). |
| Deck-Building Efficiency | 82 | Single-copy usage in 391 of 400 decks, no garnet or lock, and a slot that fits the archetype core (observed). |
Calculation
Weight profile: 0.7 Starter / Combo enabler + 0.3 Extender. Intrinsic ≈ 59, Deck ≈ 65, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in every sampled Rokket, Dragon Link and Borrel build, at one copy per deck
- Two summon routes that convert Graveyard monsters into board presence
- Clear, once-per-turn-limited text with no timing ambiguity
Weaknesses
- Needs a Rokket monster in the Graveyard for either effect
- No card advantage, search, or draw
- No negation or removal, so it adds nothing defensively
Counters / choke points
- Spell-level negation or disruption that responds to activation (general category, not from evidence)
- Opponent Graveyard or banish hate that removes the Rokket Graveyard requirement (inferred)
Best use
Starter / Combo enabler: Fusion or Ritual summon from the Graveyard in Rokket-based lines. Decks: Rokket, Dragon Link, Borrel. Suggested copies: 1.
Evidence & gaps
- Verified: Two effects, each once per turn, requiring a Rokket monster in the Graveyard; Present in 400 of 400 sampled decks at average 1.02 copies; Spell with no body and no search, draw, negation, or removal text
- Observed: Co-occurs with Absorouter Dragon, Borrelend Dragon, Striker Dragon, Rokket Tracer and Boot Sector Launch in 100% of decks; Single recorded combo reaches a full board with power index 100; Inclusion 95-100% in the Rokket and Dragon Link usage statistics
- Inferred: Graveyard-to-board conversion is roughly card-neutral; Exposure to spell-level interaction is a realistic risk for a single-card line
- Data gaps: combo data records zero starter role and searched-for role roles, and the single example has an empty combo role, so the starter role is inferred from text rather than confirmed by combo data Only one recorded combo, so combo_conversion and average power index rest on a single sample No banlist token; 3 copies assumed legal copies is empty for all formats, so legal copy limits are unconfirmed Archetype names repeat across IDs (Rokket under four IDs, Dragon Link under two), which may split or inflate the archetype counts
