• Primary strategy: Midrange
• Secondary strategies: Combo, Mechanic: Fusion/Xyz/Link
• Format: duel-links

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Thunder Dragon Colossus and Thunder Dragon Titan fusion boards, closed out by Bystial and Chaos Dragon Dragon-type beatsticks (ATK 2500 to 3200); Bystial Lubellion and Bystial Saronir banish-and-summon chains through the GY to build a board on the opponent's turn
• Turn 1 (going first): Open a Thunder Dragon searcher (Dragonroar, Thunder Dragon or Dragondark), search a second Thunder monster, then fuse Colossus or Titan while holding Ghost Belle or Crow for the opponent's first response
• Turn 2 (going second): Respond with Ghost Belle or D.D. Crow to the opponent's first summon or set, then rebuild through the GY with Lubellion, Saronir or Dragonhawk and finish with a fusion
• Recovery: Recycle searchers from the GY and banish zone (Dragonroar, Thunder Dragondark, Dragonhawk shuffle) and use Branded Regained to draw back a banished monster
• After siding: Not applicable: Duel Links is single-game and the deck carries no Side Deck

Why it scores here

The deck reliably opens a Thunder Dragon searcher: 14 searcher-text copies give about a 0.97 chance of at least one in a five-card opening hand (Inferred, hypergeometric). Conversion relies on the Colossus and Titan fusion engine and a banish-and-summon Bystial chain, but no recorded boards exist, so the ceiling is text-based and the median is not measured. Seven hand traps (Nibiru, two D.D. Crow, two Ghost Belle, and others) give about 0.83 for at least one in a six-card going-second hand, which supports the going-second score. Interaction is wide (removal text on 13 cards) but depends on conditional costs, so it is scored moderately. Popularity and archetype usage did not earn points; the score comes from the system's consistency, median output and interaction, not from averaging card scores. Side Deck, matchup and meta fit are unmeasured and kept at provisional values.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo as secondary read from the fusion/Xyz/Link extra-deck breakdown, not blended into weights. Structural ≈ 67, Going First ≈ 67, Going Second ≈ 71, Meta = provisional, Tournament Reliability ≈ 63. Modifiers: engine conflict (-2); searcher redundancy (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*67.1 + 0.20*63 - 1 ≈ 65

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High searcher density (14 searcher-text copies) gives near-certain starts
• Seven hand traps give good going-second interaction
• Fusion, Xyz and Link boss monsters with ATK 2500 to 3200 close out boards
• Multiple recursion routes (Dragonroar, Dragondark, Dragonhawk, Branded Regained) support grinding

Weaknesses

• No Side Deck, so the deck cannot adapt between games in a best-of-3 format
• Bystial split (8 copies) and generic cards (9 copies) weaken engine coherence
• No recorded boards, so the combo ceiling and median cannot be verified
• Several hand-trap and removal effects have conditional costs (tribute, discard, GY targets)

Critical choke points

• Thunder Dragon Colossus and Thunder Dragon Titan need Thunder monsters on the field or in hand, so a hand with searchers but no second Thunder monster can stall the fusion
• Bystial summons need a Dragon tribute, so a hand with Bystial pieces but no DARK or LIGHT Dragon to send stops the chain

Recommended changes

Evidence & confidence

• Verified: Legal status: 30 main, 9 extra, 0 side within Duel Links size rules (20-30 / 0-9 / 0-9); Copy counts and Main/Extra composition (16 distinct main, 6 distinct extra); Card text, stats and banlist status for every card (Limited Allure of Darkness at 1 copy; Semi-Limited Bystial Druiswurm and Magnamhut at 1 copy each, under the legal limit of 2); Archetype purity split: 16 Thunder Dragon, 8 Bystial, 9 generic, 2 Branded, 2 D.D., 1 Knightmare, 1 Orcust
• Observed: Two guides exist for the archetype; both state it was strong and then nerfed but remains viable (Guide snippets, not measured results)
• Inferred: Searcher opening access about 0.97 and going-second hand-trap coverage about 0.83 (hypergeometric); Combo ceiling and median from card text only, with no recorded boards; Interaction, going-second and closing ratings from card text; Engine conflict from the Bystial split
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13); Side Deck adaptability (D12, Duel Links is single-game with no Side Deck)
• 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 and going-second results, matchup results and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample usage_statistics inconsistency: core_cards marks Number 68, Dingirsu, Thunder Dragon Colossus and Underworld Goddess as in_this_deck false / 0 copies, but the cards array lists them in the Extra Deck with 1, 1, 3 and 1 copies. core_present_pct (41.7%) is therefore unreliable and was not used for scoring Thunder Dragon Titan is in the deck (2 copies) but is absent from usage core_cards, so usage coverage is incomplete
