  • Intrinsic: 49 · Deck: 53 · Meta: provisional

Why it scores here

Ocean of Regeneration reliably converts one WATER monster with 1000 or less ATK from the GY into a temporary body that is destroyed in the End Phase, so its value is a same-turn material or summon enabler, not a lasting board presence. Its 153-deck footprint across 31 archetypes shows it is a portable staple that fits many homes, and it is cheap to run at a typical 1 to 2 copies. The 5000-ATK-style stat line is irrelevant here; the score comes from access to a qualifying GY target and from the body it leaves as material. Combo evidence is absent, so the combo and synergy numbers rest on text and deck co-occurrence rather than observed boards.

Axis scores

Axis Score Evidence
Accessibility 45 Needs a qualifying WATER monster of 1000 or less ATK already in the GY, with no searcher evidence in the pack; deck inclusion is high but the target condition limits live turns (text + deck data, inferred for the GY condition).
Combo & Conversion 40 No combo data rows, so conversion is text-only: one temporary body per turn, with no observed board outcomes (inferred).
Resource Economy 35 No card advantage or refuel: it spends the card for a temporary summon with no net gain (verified from text).
Effect & Interaction 5 No negation, removal or hand-trap reach; it is a pure summon effect (verified from text).
Material Utility 55 The summoned monster can serve as Fusion, Link or Xyz material within the turn, but it is destroyed at End Phase and is limited to WATER monsters with 1000 or less ATK (verified text, inferred use).
Resilience & Flexibility 40 Once-per-turn, GY-targeted, and a Continuous Spell that spell-removal can clear; the revived monster is destroyed each turn, so redundancy is low (verified text, inferred).
Deck-Building Efficiency 70 Typical 1 to 2 copies (avg 1.44 per deck), no garnet or lock restriction, and 31 distinct archetypes show it slots in cleanly (observed deck stats).

Calculation

Weight profile: 0.7 Utility + 0.3 Material body. Intrinsic ≈ 49, Deck ≈ 53, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Portable across 31 archetypes and 153 decks, so it is not tied to one home (observed)
  • Cheap to run at 1 to 2 copies with no garnet or lock restriction (observed)
  • Gives a same-turn material body for Fusion, Link and Xyz lines (inferred from text)

Weaknesses

  • Needs a qualifying WATER monster of 1000 or less ATK in the GY (verified from text)
  • Destroyed in the End Phase, so it is a one-turn body with no lasting board presence (verified from text)
  • No card advantage or opponent interaction (verified from text)
  • No combo evidence, so board-level conversion is unmeasured (data gap)

Counters / choke points

  • Spell-removal or Spell-destruction effects that clear the Continuous Spell (inferred)
  • Banishing or otherwise removing the WATER monster in the GY before activation (inferred)

Best use

Utility: same-turn material or summon enabler for WATER monsters in the GY. Decks: Gishki, Ice Barrier, White Aura, Shark, Marincess, Ghoti, Umi, Penguin, Crystron.

Evidence & gaps

  • Verified: Target 1 WATER monster with 1000 or less ATK in GY, Special Summon it, destroy it in End Phase, once per turn (card text); 153 decks, 95.4% in gameplay 7, avg 1.44 copies (deck data); Legal in TCG, OCG and MasterDuel (card.formats)
  • Observed: Appears in 31 distinct archetypes (deck data.distinct archetypes); Gishki inclusion 66.7% with typical 2 copies (usage statistics); Top partners Marincess Coral Anemone 65.4% and Ash Blossom 64.7% (deck data)
  • Inferred: Acts as same-turn material for Fusion, Link and Xyz lines (text-based inference, no combo rows); Limited live-turn frequency due to the GY target condition
  • Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no top-card ranking; not in top-card data
