Megalith Deck #773279 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±12 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Megalith Notrah Plura (3700 ATK) and Drytron Meteonis Draconids (4000 ATK) ritual bosses, backed by Firewall Dragon Singularity and Worldsea Dragon Zealantis; Mulcharmy and Drytron Alpha/Gamma/Nu II/Zeta beatdown through a Ritual and Drytron board
• Turn 1 (going first): Search a Megalith or Drytron piece with Megalith Anastasis or Meteonis Drytron, then ritual or Drytron-summon a boss while holding a hand trap (Ash Blossom, Effect Veiler, Ghost Belle) to protect the line
• Turn 2 (going second): Respond to the opponent's board with Droll and Lock Bird, Maxx C, Red Reboot or Solemn cards, then rebuild a ritual boss from the hand or GY
• Recovery: Megalith Phuloch and Megalith Phul re-add Ritual Monsters from the GY, and Drytron Nu II and Drytron Mu Beta Fafnir recycle Drytron cards
• After siding: Not evaluable: the list has no Side Deck, so no post-side plan exists in the export

Why it scores here

The Megalith and Drytron core is dense enough to usually find a starter: the Megalith searchers and Meteonis Drytron together give about 0.91 odds of at least one searcher in a 5-card opening hand, and the archetype core group is about 0.78 live. Structure favours the deck: the Ritual Monster and Drytron lines offer a high-power boss package, and the ten hand traps plus Solemn and Red Reboot add real interaction, at about 0.72 odds of a hand trap in six cards when going second. Against that, the deck is only 11 percent exact-archetype. It carries 62 off-archetype copies across Mulcharmy, Cyber Angel, Cyber Dragon, Herald and others, and it has 21 singleton main-deck slots, so the bricking risk and the number of unrelated pieces weigh on the score. No combos, guides or tournament records exist, so the combo and meta reads are text-only and Inferred. The score was not produced by averaging card scores or by the archetype's popularity; the list is Illegal because five Forbidden cards are over the OCG limit, so the Final value is capped and the result is theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange 100 (no secondary blend applied to weights). Structural ≈ 49.5, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 47.6, then banlist-exposure modifier -12 = 35.6, then capped to 25 because the deck is Illegal

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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 starter density with about 0.91 odds of a searcher in the opening hand (Inferred)
• Ten hand traps and several negation cards give layered interaction (Inferred)
• High-ATK ritual and link bosses give strong closing power if the line resolves (Verified stats)

Weaknesses

• Illegal as built: five Forbidden cards over the OCG limit
• Low archetype purity (11.4 percent exact name) with 62 off-archetype copies, so the engine is incoherent
• No Side Deck, so best-of-three adaptation is absent
• No recorded combos, guides or tournament data to confirm the lines

Critical choke points

• Each ritual boss needs a specific Ritual Monster or Ritual Spell to be in hand, so one missed starter breaks the line
• Drytron lines depend on Meteonis Drytron or Drytron Fafnir in hand
• The five Forbidden Extra Deck cards are the main Extra Deck access and must be removed or replaced before the deck is legal

Recommended changes

Evidence & confidence

• Verified: Illegal status: five Forbidden OCG cards run at 1 copy each over the 0-copy limit; Main 55 and Extra 15 are within the OCG size rules; Side is 0 with a maximum of 15; Archetype purity 11.4 percent exact-name; 8 Megalith copies out of 70; Searcher, hand-trap, negation and removal counts from the card text scaffold
• Inferred: Opening-hand probabilities (0.91 searcher, 0.78 core, 0.72 hand trap going second); Brick risk from singleton density and Tribute-dependent ritual lines; Interaction density and resilience read from text
• Provisional: Meta and format fit, because no dated metagame sample or tournament link exists
• Data gaps: No combos supplied, so the combo floor, median and ceiling are text-only (Inferred) No tournament link, so archetype meta-share and per-pilot records are absent No Side Deck, so the post-side plan and D12 cannot be measured No win-rate telemetry exists for going-first, going-second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied
