Chaos Deck #762999 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Midrange
• Format: tcg

Legality

Main 48 / Extra 21 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ritual or Fusion Summon a large Mitsurugi, Chaos or Dark Magician boss (Ame no Murakumo no Mitsurugi 3200 ATK, Master of Chaos 3000 ATK, Timaeus 2800 ATK) and convert the board advantage into attacks.; Link and Xyz boards (Underworld Goddess, Accesscode Talker, Super Starslayer TY-PHON) for board-clearing or extra attacks, subject to the Extra Deck overflow.
• Turn 1 (going first): Open with a hand-trap-backed starter (Mitsurugi monsters or Mitsurugi Ritual) and hold Ash Blossom, Infinite Impermanence or Effect Veiler for the first opposing summon. (Inferred)
• Turn 2 (going second): Use Droll & Lock Bird, Evenly Matched and Called by the Grave to slow the opponent's extension, then rebuild through the Mitsurugi Ritual line. (Inferred)
• Recovery: Recover through Mulcharmy Fuwalos, Magicians' Souls and Mitsurugi searchers, but only if the hand has enough cards to fund the Ritual tributes. (Inferred)
• After siding: Not evaluable: the deck has no side deck (Side Deck size 0), so there is no post-side plan.

Why it scores here

This 48/21/0 list is Illegal under TCG rules: the Extra Deck is 6 cards over the 15-card maximum, three copy-limit violations exist, and Bagooska is a Forbidden card run once. Under the Toolbox profile the structure is a split engine: the archetype core (17 copies, about 0.90 chance of at least one in a 5-card opening hand, Inferred) is spread across Mitsurugi, Dark Magician, Timaeus and Magician sub-engines with only 4 exact-name Chaos copies. The 13 hand traps and 14 negation-text cards give the deck real interaction (D7 60), and its Ritual and Fusion ceiling is high (Ame no Murakumo, Master of Chaos), but there are no recorded boards, so ceiling and median are text-only inferences. The score comes from consistency, interaction and closing power on the system as a whole, not from averaging the card powers. Popularity or usage stats were not counted, because the Chaos core list is absent from this build. The Illegal status caps the score, so this is a structural-only read.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; Midrange not blended into weights. Structural ≈ 45, Going First ≈ 42, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-6); extra_deck_overflow_dependence (-2). Final formula: Illegal cap applied. Theoretical formula before cap: 0.80*45 + 0.20*30 + modifiers(-8) = 34; capped to 20 because the deck is Illegal. Meta Power is null (provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher and hand-trap package gives many ways to find and protect a starter (Inferred)
• Layered interaction: 13 hand traps, Lightning Storm, Infinite Impermanence and Mitsurugi Great Purification (Inferred)
• High-end closing bodies in the Extra Deck: Ame no Murakumo, Master of Chaos, Timaeus (Verified stat)

Weaknesses

• Illegal: Extra Deck over limit, three copy-limit violations and a Forbidden card (Verified)
• Split engine: only 4 exact-name Chaos copies and 65 off-archetype copies across four sub-archetypes (Verified count, Inferred effect)
• No side deck, so there is no post-side adaptation (Verified)
• No recorded boards, so the ceiling and median output cannot be verified (Verified gap)

Critical choke points

• Mitsurugi Ritual and the Ritual Monster tributes: a dead Mitsurugi hand loses the main engine (Inferred)
• Extra Deck size: a legal 15-card build must cut 6 Extra Deck cards, which removes some of the closing options (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality: Extra Deck 21 > 15; Ash Blossom 3 vs 2; Mitsurugi Prayers 3 vs 1; Bagooska Forbidden 1 copy; Main Deck count 48 within 40–60; hypergeometric values from the evidence pack
• Inferred: Consistency estimates (P of starters, brick rates) from the hypergeometric pack and card text; Engine split and closing-power reads from card text
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13)
• 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 absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) No side deck (Side Deck size 0) Meta Power is provisional unless a dated metagame sample is supplied
