Bystial/Byssted Deck #773106 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Neo Blue-Eyes Ultimate Dragon 4500 ATK, Blue-Eyes Tyrant Dragon 3400 ATK, Blue-Eyes Ultimate Spirit Dragon 3500 ATK) reached through a hand-trap-protected board; no recorded line confirms this; Link and Synchro beaters (Lightstorm Dragon, Super Starslayer TY-PHON, Imduk) once the board is stable
• Turn 1 (going first): Open with Sage with Eyes of Blue / Maiden of White / Primite Dragon Ether Beryl to search, and hold Ash Blossom, Infinite Impermanence and Droll & Lock Bird as interaction; no verified turn-1 combo exists in the evidence
• Turn 2 (going second): Hold 6 cards with 17 hand traps (about 90% chance of at least one hand trap) and negate the opponent's first board, then rebuild through Mulcharmy draws and Blue-Eyes Extra Deck summons
• Recovery: Recover through searchers (15 copies, about 80% at least one in a 5-card hand), Pot of Prosperity and Mulcharmy draw effects; this is text-based and unverified against recorded boards
• After siding: Not available: the deck runs no side deck (Side Deck size 0), so there is no post-side plan

Why it scores here

This list is Illegal in OCG because it runs 3 copies of Ash Blossom & Joyous Spring against a limit of 2, so the score is theoretical and structural only and is capped at 30. The deck is a fragmented hand-trap toolbox rather than a single engine: exact-name archetype purity is 0% (71 off-archetype copies spread across Blue-Eyes, Primite, Mulcharmy, with Eyes of Blue, Greed and Dominus), and the core Bystial Druiswurm is absent. Its strongest axis is interaction, with 17 hand traps and 14 negation-text cards giving about a 90% chance of at least one hand trap in a 6-card going-second hand, and this is scored from card text (Inferred). Starter access is moderate: the searcher group reaches about 80% in a 5-card hand, but the archetype core reaches only about 55%, and no recorded boards exist to confirm a combo floor, median or ceiling. The score comes from consistency, interaction and Extra Deck power on the system; it does not come from the individual card scores, from the popularity of Bystial, or from averaging card power.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 49, Going First ≈ 50, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: illegal copy-limit violation (-6); engine conflicts / fragmentation (-5); hard-garnet burden (0); illegal-list cap (0). Final formula: No reliable metagame: 0.80*Structural(48.6) + 0.20*TournamentReliability(42) + ContextModifiers(-11) = about 36, then capped at 30 because the list is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · key two-card combo ≈ — · full-brick estimate ≈ 0.45 (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 suite: 17 hand traps and 14 negation-text cards
• High Extra Deck ceiling with Neo Blue-Eyes Ultimate, Blue-Eyes Tyrant and Blue-Eyes Ultimate Spirit
• Searcher density (15 copies) gives reliable access to a live hand

Weaknesses

• Illegal in OCG: Ash Blossom copy limit exceeded
• No exact-name archetype core; engines split across Blue-Eyes, Primite, Mulcharmy and Greed
• No side deck and no recorded combo boards to validate the plan

Critical choke points

• The Blue-Eyes Extra Deck boss lines depend on Blue-Eyes White Dragon (2 copies) plus Mausoleum/Roar access; a single lost line leaves a hand of hand traps with no board
• Ash Blossom's copy count must drop to 2 before any evaluation of the deck as legal

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring at 3 copies against an OCG legal limit of 2 (Semi-Limited); All other restricted cards (Bystial Magnamhut, Droll & Lock Bird, Pot of Prosperity, S:P Little Knight, Solemn Judgment) run at 1 copy and are legal; Main 56 and Extra 15 are within size rules; side deck is empty; Usage stats: Bystial Magnamhut 85%, Droll 63%, Bystial Druiswurm 61% (absent), Mulcharmy Fuwalos 60%, Ash 57%; Card text read from the evidence excerpts
• Inferred: Searcher, starter and hand-trap probabilities from the hypergeometric table; Interaction density and resilience from card text; Going-first and going-second estimates from hand-trap coverage
• Provisional: Meta Power is null and format fit is provisional: no dated metagame sample or tournament link exists
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck has no side deck, so post-side performance cannot be assessed deck title is null; evaluated by archetype and card list only
