Dinomorphia Deck #773314 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±12 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Large Dinosaur bodies (Ultimate Conductor Tyranno 3500 ATK, Dinomorphia Kentregina 4000 ATK, Dinomorphia Rexterm 3000 ATK, Transcendosaurus Drillygnathus 3000 ATK) reached through Jurrac and Dinomorphia summon chains; text-only read, no recorded boards.; Board-wipe or mass-destruction followups: Jurrac Meteor (destroys all cards on the field on Synchro Summon) and Jurrac Impact (destroys all cards if a 2500+ ATK Dinosaur is controlled).
• Turn 1 (going first): Opening Fossil Dig or Ground Xeno, or a Jurrac/Dinomorphia starter (Jurrac Megalo, Jurrac Aeolo, Souleating Oviraptor, Dinomorphia Therizia), to Synchro or Fusion into a Dinosaur boss while holding Ash Blossom and Ghost Belle for the opponent's responses.
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, or Droll & Lock Bird to negate the opponent's first search or summon, then rebuild a Dinosaur board from the Graveyard through Jurrac Aeolo and Dinomorphia Diplos.
• Recovery: Dinosaur monsters that Special Summon themselves from the Graveyard when destroyed (Petiteranodon, Babycerasaurus, Ghost Belle, Dinomorphia Diplos) to rebuild a board after a wipe, and Ground Xeno's Fusion effect from the Graveyard.
• After siding: Not evaluable: side deck is empty (0 cards), so there is no post-side plan in the evidence.

Why it scores here

The deck is illegal as submitted: it runs three copies of Ash Blossom & Joyous Spring against an OCG limit of two, so it receives a structural-only cap rather than a normal Final Contextual score. Its structural read rests on a Dinosaur system: the archetype core group is open in 5-card hands about 82% of the time (hypergeometric, Inferred), a searcher is present in about 69%, and at least one hand trap is present in about 71% of going-second 6-card hands. Its high ceilings (Ultimate Conductor Tyranno, Dinomorphia Kentregina, Jurrac Meteor's field wipe) come from card text only, because no recorded boards exist, so D3 and D4 are semantic inference and D4 is provisional. Archetype popularity and usage statistics were not counted as power: only 5 of 21 core archetype cards are present, and exact-name purity is 20% because the list splits between Jurrac and Dinomorphia. The score is derived from the 14 system dimensions and was not averaged from card scores. The side deck is empty, which pulls D12 down and leaves no post-side plan.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55.3, Going First ≈ 58, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (-6); Weak or absent post-side plan (-4). Final formula: Illegal deck: theoretical/structural-only. Uncapped 0.80*Structural(55.3) + 0.20*TournamentReliability(48) + modifiers(-10) ≈ 44, capped to 30 per the illegal-deck rule. Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core archetype cards are reliably present (5-card hand ≈ 82%, Inferred).
• Seven hand traps and two field-wipe effects give layered interaction.
• Fusion, Synchro and XYZ bosses reach 3000+ ATK, with a full 15-card Extra Deck.

Weaknesses

• Illegal as submitted: Ash Blossom & Joyous Spring is over its OCG limit.
• No side deck, so there is no post-side adaptation.
• Split between Jurrac and Dinomorphia (exact-name purity 20%) weakens engine coherence.
• Only 5 of 21 usage-stat core cards are present.

Critical choke points

• Ash Blossom over the limit: the third copy has to go before this list is legal.
• Dinosaur summon chains depend on Jurrac Megalo, Jurrac Aeolo or Oviraptor as the first starter.

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 against OCG size rules.; Ash Blossom & Joyous Spring 3 copies vs legal limit 2 (Semi-Limited).; Extra Deck breakdown: 9 Synchro, 4 Fusion, 2 XYZ.; Usage stats: 5 of 21 core cards present (23.8%).
• Inferred: Opening-hand probabilities (archetype core ≈ 0.82, searcher ≈ 0.69, hand trap ≈ 0.71 going second).; Dinosaur engine conversion and recovery from text.; Interaction density and board-wipe role from card text.
• Provisional: Meta Power (null) and D13 matchup/format fit (neutral 50).; D4 floor and median output (no boards).
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot match record are absent. No win-rate telemetry (going-first/second, matchup, brick/starter rates). Meta Power is provisional without a dated metagame sample. Side deck is empty, so post-side performance cannot be assessed. No guides attached to the archetype.
