Thunder Dragon Deck #772431 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Control
• Format: ocg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Fusion-summon boss monsters (Hyperinvoked Aeon, Invoked Oceanus, Invoked Mechaba, Thunder Dragon Colossus) from an Aleister-led Invoked engine; Link and Fusion beatdown with Thunder Dragon Colossus and Invoked Magistus Omega once the field is established
• Turn 1 (going first): Open with Aleister the Reminiscent, Invocation, Invocation - Grail or Sword, and Virakam to search and Fusion Summon an Invoked boss; negate or hand-trap any interaction
• Turn 2 (going second): Use Ash Blossom, Ghost Belle, Droll & Lock Bird and Forbidden Droplet to answer the opponent's first line, then rebuild through the Aleister searchers and GY-based Invocation and Gamma Summon recursion
• Recovery: Recover from GY and banish: Invocation or Gamma Summon re-summons Invoked monsters, Thunder Dragonroar and Thunder Dragondark recycle Thunder Dragon cards, and Aleister searches reload the Aleister engine
• After siding: No side deck is registered, so no post-side plan can be scored; the deck has no sided answers to a known matchup

Why it scores here

This list is Illegal (Ash Blossom & Joyous Spring is run at 3 copies against a limit of 2), so it receives a capped, theoretical-only structural read rather than a normal contextual score. Its opening access is moderate: each 3-copy engine card has about 25% odds of appearing in a 5-card going-first hand, and the 20 searcher-text cards give about 90% odds of at least one search effect, both inferred from hypergeometric estimates. The interaction package is the deck's clearest strength: 6 hand traps and 16 negation-text cards give it real going-second answers (Inferred). Its floor is unmeasured, since no boards were recorded, and the Thunder Dragon label is not supported by the list, which runs only 4 exact-name Thunder Dragon cards against 67 off-archetype copies. Popularity did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 47, Going First ≈ 46, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-4); archetype_label_mismatch (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*47 + 0.20*35 = 44.6, then modifiers (-4) gives 40.6, then the Illegal cap applies and the final score is 30 (theoretical, structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Layered interaction: 6 hand traps and 16 negation-text cards cover going-second
• Strong Extra Deck bosses (Hyperinvoked Aeon 3800, Invoked Oceanus 3000, Invoked Mechaba 2500) with 15 Extra slots used efficiently
• Recursion via Invocation, Gamma Summon and Thunder Dragonroar

Weaknesses

• Illegal list: Ash Blossom at 3 copies over its limit of 2
• Large off-archetype share: 67 copies, only 4 exact Thunder Dragon cards
• No Side Deck, so no post-side plan
• Brick-prone: 14 tech slots and 14 cards at 3 copies

Critical choke points

• Aleister the Reminiscent and Aleister searchers are needed for most Fusion lines
• Ash Blossom and Ghost Belle are the main going-second answers and both are needed

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom at 3 copies exceeds the Semi-Limited limit of 2 (Illegal); Main 56 and Extra 15 are within OCG size rules; Limited cards (Droll, Harpie's Feather Duster, Terraforming) are at 1 copy each, legal; Card texts and stats for resolved cards
• Inferred: Opening-hand estimates for 3-copy starters (about 25%) and searcher access (about 90%); Interaction density (6 hand traps, 16 negation texts) and its going-second value; Boss power and Fusion-line ceiling from text, with no recorded boards
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent Passcode 86120751 could not be resolved and was counted as Main Usage-stat ref IDs conflict with the card list: Thunder Dragon Colossus (15291624) is in the Extra Deck at 1 copy, but usage_statistics reports copies_in_deck 0 No Side Deck registered No win-rate telemetry; going-first and going-second splits are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
