Thunder Dragon Deck #770811 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Fusion Summon a large Invoked or Thunder Dragon boss from the Extra Deck using Aleister monsters as material, backed by Invocation and Aleister searches; Thunder Dragon Colossus and Hyperinvoked Aeon boss pressure once the field is established
• Turn 1 (going first): Search or Summon an Aleister starter (Aleister the Reminiscent, Magical Meltdown or Invocation) and convert it into an Invoked Fusion through Invocation or Invocation - Sword, with hand traps held for the opponent's first response
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle and Ghost Ogre for the opponent's first activation, then rebuild through Thunder Dragondark and Mulcharmy draw effects
• Recovery: Recover through the GY-based searchers (Invocation, Aleister the Reminiscent, Aiwass) and Thunder Dragonhawk's GY recursion
• After siding: Not evaluable: the Side Deck is empty, so no post-side plan exists in the export

Why it scores here

The deck is scored as a system, not as an average of its cards. It reliably opens a starter about half the time (P(at least one 3-copy starter in a 5-card hand) is about 0.25 for the Aleister core, while searcher text covers about 0.89 of 5-card hands), so the engine is accessible only through search density. Interaction is the strongest part of the list, with 11 hand traps and 10 negation-text cards giving it good end-board and going-second protection. Conversion is weak because no recorded boards exist, the median output is text-inferred, and only 3 of 67 off-archetype copies are on-theme. Popularity did not earn points: the Thunder Dragon core is absent (Thunder Dragon Colossus and Thunder Dragon are missing) and the list is Illegal, which caps the final score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 44, Going First ≈ 46, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-4); off_archetype_dilution (-3). Final formula: Illegal cap applied: pre-cap 0.80*Structural(44) + 0.20*TournamentReliability(35) + modifiers(-7) = 35; capped to 25 as theoretical/structural-only (Meta provisional)

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

• Dense hand-trap and negation package (11 hand traps, 10 negation-text cards)
• Strong Extra Deck boss ceiling (Hyperinvoked Aeon, Invoked Elysium, Thunder Dragon Colossus)
• Multiple searchers (19 searcher-text cards) for starter access

Weaknesses

• Illegal: Ash Blossom run at 3 copies against a limit of 2
• Empty Side Deck, so no best-of-3 adaptation
• Off-archetype diluted: Thunder Dragon core absent, purity 4.3%
• No recorded combos, so conversion is unverified

Critical choke points

• The Aleister starter line: most hands need one of the few starters to convert Fusion material
• Hand traps conflict with each other when the opponent passes on activations

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Ash Blossom run at 3 copies against a limit of 2; Main 55 and Extra 15 are within OCG size rules; Side is 0; Side Deck is empty; Exact-name Thunder Dragon purity 4.3%; Extra Deck is 12 Fusion and 3 Link monsters
• Inferred: Hypergeometric starter access ~0.25 per 5-card hand for the 3-copy core; Hand traps and negation give layered interaction; Conversion and median output estimated from text only
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament or meta sample)
• Data gaps: No combos supplied, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot record are absent 1 passcode (86120751) in CardIDList could not be resolved to a card and is counted as Main No win-rate telemetry exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied Side Deck is empty, so no post-side evaluation is possible Deck title is null
