Bystial/Byssted Deck #772994 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 34/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Blue-Eyes White Dragon and Blue-Eyes Extra Deck threats (Blue-Eyes Spirit Dragon, Neo Blue-Eyes Ultimate Dragon, Blue-Eyes Tyrant Dragon) backed by Bystial 2500 ATK beaters; Primite Dragon Ether Beryl and Albaz-line Fusion/Synchro boards
• Turn 1 (going first): Normal Summon Sage with Eyes of Blue or Maiden of White, or Set Primite Lordly Lode, then keep hand traps (Ash, Ghost Ogre, Effect Veiler) up for the opponent's first activation
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird and Effect Veiler to slow the opponent's search and summon, then Bystial Druiswurm or Magnamhut banish a GY monster to bring out a 2500 ATK beater
• Recovery: Ash and Ghost Ogre recover from interruption by sending themselves from hand; Wishes for Eyes of Blue and Bystial Saronir rebuild the Blue-Eyes and Bystial bodies from Deck and GY
• After siding: Not evaluable: the deck has no side deck (0 cards)

Why it scores here

The score comes from the deck as a system and not from averaging its cards. The deck reliably opens searchers (13 copies, about a 76% chance of at least one in a 5-card opening hand) and can run a lot of hand traps and negations (13 hand traps, 18 negation-text cards), which gives it real interruption resilience and end-board interaction. Its closing power comes from several 2500 to 4500 ATK Blue-Eyes and Bystial bodies. The main deck is not compact: 35 distinct main-deck cards, 21 tech slots, and three unrelated engines (Blue-Eyes, Bystial, Primite) with no recorded combos to prove they connect. The deck has no side deck, and it runs Triple Tactics Talent (Forbidden) plus three copies of Ash Blossom (limit 2), so it is illegal as built. Because it is illegal it does not get a normal Final Contextual score, and this 34 is a capped theoretical figure. Archetype popularity (Blue-Eyes and Bystial core cards at 57% to 85% inclusion) was not counted as power, and no tournament result supports the deck.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 47, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); no Side Deck (-2); no_combo_evidence (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 45.9, then modifiers -12, capped as Illegal = 34

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.76 · 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 searcher and hand-trap suite gives early interaction and access
• Strong late threats across Blue-Eyes and Bystial Extra Deck options
• Wide negation and removal coverage

Weaknesses

• Illegal as built: Ash Blossom over copy limit and Triple Tactics Talent Forbidden
• Three engines compete for slots, which adds bricks and tech clutter
• No side deck and no recorded combos

Critical choke points

• Single Blue-Eyes White Dragon in hand or GY gates most Blue-Eyes Extra Deck lines
• Bystial summon depends on a LIGHT or DARK monster in the GY

Recommended changes

Evidence & confidence

• Verified: Main deck 55, Extra 15, Side 0 (OCG limits 40-60, 0-15, 0-15); Ash Blossom 3 copies vs legal 2 (Semi-Limited); Triple Tactics Talent Forbidden; Card text and ATK/DEF values for the listed cards
• Observed: Archetype inclusion stats: Bystial Magnamhut 85%, Droll & Lock Bird 63%, Bystial Druiswurm 61%, Ash Blossom 57%
• Inferred: P(>=1 searcher in opening 5) = 0.76; Engine conflict across Blue-Eyes, Bystial and Primite lines; Hand-trap density gives interaction resilience
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (no tournament or meta data)
• Data gaps: no combos supplied, so floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry exists, so going-first, going-second and matchup results are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied guide snippets are empty or very short
