Endymion's Lab — Power Evaluation
Final Score: 45 ± 8 · Confidence: Medium
- Intrinsic: 43 · Deck: 46 · Meta: provisional
- Primary role: Extender
Why it scores here
Endymion's Lab is a conditional engine: it needs a Spellcaster destroyed in battle, six Spell Counters built up from resolved Spells, and then it converts those counters into one Level 7+ Spellcaster Special Summon. Its score comes from that conversion and from its live use in 49 recent decks, mainly inside the Endymion ecosystem, not from its text being strong on paper. The card has no negation, no material value, and no card advantage of its own, so those axes stay low. Without recorded combo boards, the conversion and starter claims rest on text plus deck co-occurrence, which caps confidence.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Live in 49 recent decks at 1.45 average copies, but activation needs a Spellcaster destroyed in battle first, so it is not a reliable opening-hand play. (observed) |
| Combo & Conversion | 45 | Converts six Spell Counters and a battle-destruction trigger into one Level 7+ Spellcaster from hand or Deck, a single body rather than a full board. (verified) |
| Resource Economy | 40 | Removes six counters as cost and returns one summoned body; no draw, search, or recursion is stated in the text, so the exchange is roughly even. (verified) |
| Effect & Interaction | 10 | The card text gives no negation, removal, or disruption effect. (verified) |
| Material Utility | 5 | A Continuous Spell cannot be used as material and provides no level, attribute, or name value on the field. (verified) |
| Resilience & Flexibility | 35 | Its counter pool sits in the Spell & Trap Zone and depends on Spells resolving and a battle trigger, so it is fragile across turns. (inferred) |
| Deck-Building Efficiency | 55 | One slot, no garnet requirement, but it only works in Spellcaster-heavy builds, which is a mild restriction. (inferred) |
Calculation
Weight profile: Extender weights only; no meaningful secondary role blended. Intrinsic ≈ 43, Deck ≈ 46, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in 49 recent decks across 17 archetypes, with the Endymion archetypes making up about half of them
- Strong co-occurrence with the Endymion ecosystem: Magical Citadel of Endymion in 81.6% of decks and Spell Power Mastery in 75.5%
- Can turn a Spellcaster lost in battle into a Level 7+ Spellcaster Special Summon
Weaknesses
- Needs a Spellcaster destroyed in battle plus six Spell Counters before it does anything
- Once per turn, and the card can be activated only once per turn
- No negation, removal, or card advantage of its own
- Zero recorded combo boards, so its real conversion rate is unmeasured
Counters / choke points
- No counter is stated in the evidence; the card's own text and the lack of combo data limit how much can be said about answers
Best use
Extender for Spellcaster-based Spell-counter decks. Decks: Endymion (archetype 681), Endymion (archetype 175). Suggested copies: 1.
Evidence & gaps
- Verified: Continuous Spell; six Spell Counters are removed to Special Summon one Level 7+ Spellcaster from hand or Deck, once per turn after damage calculation; Gets a Spell Counter for each Spell activated and resolved; the name changes in the Spell & Trap Zone; Used in 49 recent decks at 1.45 average copies; 17 distinct archetypes
- Observed: Top partners co-occur in 75.5% to 81.6% of the 49 decks (Magical Citadel of Endymion, Spell Power Mastery); Endymion archetypes 681 and 175 make up 26.5% and 24.5% of decks
- Inferred: Conversion depends on Spell-heavy, Spellcaster-based builds to accumulate counters and generate battle destruction; Fragile to Spell & Trap Zone removal or to a Spellcaster being protected from battle destruction
- 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 is inferred from the deck sample only no card levels or stats for the Spellcaster targets; the Level 7+ requirement is taken from text only
