Thunder Dragon Deck #767913 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion Summon Invoked boss monsters (Hyperinvoked Aeon 3800 ATK, Invoked Elysium 3200 ATK, Invoked De Anima 2900 ATK) off Aleister the Reminiscent and Invocation/Invocation - Grail, with Aiwass and Mulcharmy as draw and starter support.; Thunder Dragon Colossus and Thunder Dragonhawk recursion as a secondary Fusion/Extra pressure line.
• Turn 1 (going first): Open Aleister-based starters (Aleister the Reminiscent, Aiwass, Sorcerer of the Swamp) and search Invocation or Invocation - Grail to Fusion Summon an Invoked boss; hold Ash Blossom and Ghost Belle as interaction.
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Droll & Lock Bird, Evenly Matched) to stop the opponent's first play, then rebuild through Aleister or Virakam.
• Recovery: Recover through Thunder Dragondark and Thunder Dragonhawk from the GY/banish, and Pot of Sloth for card advantage, to rebuild Aleister and a Fusion boss.
• After siding: Not evaluable: the Side Deck is empty (0 cards), so no post-side plan is present.

Why it scores here

The deck is scored as a system, not as an average of its cards. Its engine is Aleister and Invocation Fusion lines: searchers (about 89% chance of at least one searcher in a 5-card opening hand) and Aleister the Reminiscent (3 copies, about 56% chance to open with an Aleister-core card) give reasonable starter access, but there are no recorded combos to measure conversion, so the ceiling and median are text-based inference only. Interaction is dense (11 hand traps, 10 negation texts, 23 removal texts), and the going-second hand-trap coverage (about 76% for a 6-card hand) supports resilience. Closing power comes from 3800 and 3200 ATK Invoked bosses, but the list runs 14 triple-copy cards, 25 distinct Main Deck cards, and one unresolved passcode, so consistency is pulled down. The deck is Illegal: 3 copies of Ash Blossom & Joyous Spring exceed the OCG Semi-Limited limit of 2, so it receives a low structural-only score. Popularity and archetype share did not earn points, since no tournament data was supplied and the Thunder Dragon archetype label is only 3 exact-name cards in the list.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 45, Going First ≈ 40, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-6); engine_conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); illegal deck, structural-only, capped low: 0.80*45.25 + 0.20*35 - 8 = 35

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Dense interaction: 11 hand traps and 10 negation texts
• Searcher density (about 89% at least one in a 5-card opening hand)
• High-ATK Invoked Fusion bosses in the Extra Deck

Weaknesses

• Illegal as built: 3 copies of Ash Blossom & Joyous Spring against a limit of 2
• No Side Deck
• Many triple-copy cards and a single unresolved passcode reduce flexibility

Critical choke points

• Aleister the Reminiscent is required by most Fusion lines; without it the Extra Deck is largely dead
• Invocation/Grail access depends on a live Aleister in field, GY, or banishment

Recommended changes

Evidence & confidence

• Verified: Main Deck 55 cards (within 40-60) and Extra Deck 15 cards (within 0-15); Ash Blossom & Joyous Spring: 3 copies run, legal limit 2 (Illegal); Side Deck is empty; Terraforming, Harpie's Feather Duster, and Droll & Lock Bird are each run at 1 copy, within their Limited limit; Exact-name Thunder Dragon purity is 4.3%
• Inferred: At least one searcher in a 5-card hand ≈ 0.89; Aleister core in a 5-card hand ≈ 0.56; Going-second hand-trap coverage ≈ 0.76; Interaction density is high from card text; Invoked boss ceiling if Fusion access is live
• Provisional: Meta Power and matchup fit: no dated meta sample or tournament link
• Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent 1 passcode (86120751) in the list could not be resolved and was counted as Main No win-rate telemetry for going-first/second, matchups, or brick rate Meta Power is Provisional with no dated metagame sample Side Deck is empty, so post-side behavior cannot be evaluated
