Mature Chronicle — Power Evaluation

Why it scores here
Mature Chronicle converts Yubel Special Summons into a stockpile of counters that can be spent on a Yubel revival from the GY, a card draw from banished cards, a Super Polymerization search, or a destroy effect. Its power comes from that conversion engine and its deck slot cost, not from any stat, and the card is a 1-of with no garnet or lock restriction. Its material value is near zero because it is a Continuous Spell, and the lack of recorded combo data keeps the combo axis near the middle of the range. High deck presence (400 of 400 sampled decks) confirms that the card is played, but it is not counted as evidence of strength.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Counters only accumulate when Yubel-linked monsters are Special Summoned, so the card is live only in Yubel-type shells; the sample shows it in all 400 decks, which confirms access in practice but not a starter route (observed, inferred). |
| Combo & Conversion | 58 | The text converts stored counters into a Yubel revival or a Super Polymerization search, and the guide describes it as the support that lets Yubel Super Polymerize the opponent's field, but no combo boards were recorded (inferred, verified). |
| Resource Economy | 60 | Mode 2 and mode 5 each gain one card and mode 3 spends deck cards as a cost; there is no card-cost-free refuel beyond the counter economy (verified, inferred). |
| Effect & Interaction | 45 | Mode 4 destroys one card on the field, but it is counter-gated and once per turn, so it is soft interaction rather than strong removal (verified). |
| Material Utility | 5 | A Continuous Spell cannot be used as material, so the body contributes nothing once it is on the field (verified). |
| Resilience & Flexibility | 40 | The card sits face-up on the field, so backrow removal or Spell destruction ends its counter engine, and the once-per-turn limit restricts repeated use (inferred). |
| Deck-Building Efficiency | 65 | One copy is run in 381 of 400 decks, with no garnet or self-lock recorded and a clean single slot, but the card needs a Yubel-heavy shell to function (observed, verified). |
Calculation
Weight profile: 0.7 Extender + 0.3 Searcher/Tutor. Intrinsic ≈ 53, Deck ≈ 57, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts Yubel summons into counters that fuel a Yubel revival, a card draw, and a Super Polymerization search
- Single-copy slot with no recorded garnet or self-lock restriction
- Included in all 400 sampled decks, so access in practice is consistent within Yubel shells
Weaknesses
- Continuous Spell with no material value and no direct board-building effect of its own
- Counter generation depends on a Yubel-linked summon first, so it is dead in non-Yubel homes
- Once-per-turn limit on its effects and no recorded combo data to confirm conversion from a realistic start
Counters / choke points
- Backrow removal or Spell destruction, which ends the face-up engine (inferred)
- Monster-effect negation that stops the Yubel summons generating counters (inferred)
Best use
Extender: Yubel-support engine (recursion and Super Polymerization search). Decks: Yubel, Unchained, Fiendsmith. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: counters from Yubel summons, five modes, once-per-turn clause; Present in 400 of 400 sampled decks, 1 copy in 381 of them; Co-occurs with Super Polymerization in 88.8% of decks
- Observed: Yubel archetype accounts for 39.8% of sampled decks, Unchained 21.5%, Fiendsmith 10.8%; Gameplay type 7 in 86% of decks
- Inferred: Live only inside Yubel-linked shells, so access is conditional; Mode 4 is soft interaction because it is counter-gated and once per turn; Vulnerable to face-up Spell removal
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only
