The Book of the Law

The Book of the Law — Power Evaluation

Final Score: 46 ± 6 · Confidence: Medium

• Intrinsic: 43 · Deck: 47 · Meta: provisional
• Primary role: Extender · Secondary: Combo enabler, Utility

Why it scores here

The Book of the Law is a conditional Invoked extender: it Tributes an Invoked monster you already control to Special Summon a different-Attribute Invoked Fusion from the Extra Deck, so it does nothing without the Aleister/Invocation line already resolved. It converts one existing body into a different Invoked Fusion (Mechaba, Raidjin, Augoeides, Caliga, etc.), trading one card for a body swap rather than generating advantage, which keeps its combo ceiling and resource economy moderate. Its no-ATK Quick-Play Spell stats earn nothing here — the score is driven by a hard setup requirement, an even-to-negative card trade, and the fact that it provides no inherent disruption of its own. Deck evidence (392 lists, ~1.07 copies, 99% alongside Aleister) confirms it is a real, recurring Invoked flex slot rather than a forgotten pick, while the complete absence of combo data caps confidence.

Axis scores

Calculation

Weight profile: 0.7 Extender + 0.3 Utility. Intrinsic ≈ 43, Deck ≈ 47, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Converts an existing Invoked body into a different-Attribute Invoked Fusion, granting access to a variety of Invoked effects (negation, flipping, stat changes)
• Quick-Play timing allows reactive use once the Invoked line is already on board
• Cheap to include as a 1-of flex slot with no extra garnets beyond the standard Invoked engine
• Observed in 392 decks well over years, confirming it is a live recurring Invoked option, not a niche pick

Weaknesses

• Does nothing without an Invoked monster already on the field, so it is a pure 2-card-plus setup card
• Trading one Invoked body for another is roughly card-neutral and provides no card advantage
• Provides no disruption of its own; its interaction depends entirely on the Invoked Fusion chosen
• Hard once-per-turn clause limits repeat use
• No searcher route is demonstrated, making it reliant on being drawn

Counters / choke points

• Removing the Invoked monster before this resolves leaves it dead in hand
• Ash Blossom & Joyous Spring / Droll & Lock Bird disrupting the Aleister engine prevents the setup entirely
• Graveyard- and Special Summon-negating interaction (e.g. Called by the Grave on the relevant Invocation targets) blunts the engine

Best use

Flexible 1-of extender that swaps the Invoked Fusion to match the needed effect. Decks: Invoked, Invoked Magistus, Invoked Dogmatika, Invoked Shaddoll. Suggested copies: 1.

Evidence & gaps

• Verified: Tribute 1 "Invoked" monster; Special Summon 1 different-Attribute "Invoked" monster from the Extra Deck, treated as a Fusion Summon; You can only activate 1 "The Book of the Law" per turn; It is an Invoked-archetype Quick-Play Spell with no inherent ATK/DEF and no built-in disruption; 392 sampled decks run it, 392 in the main deck, 0 in the side
• Observed: Average 1.07 copies per deck, with 370 lists at 1 copy, 18 at 2, and 4 at 3; Co-deck rates with Aleister (99%), Invocation (98.7%), and Magical Meltdown (95.4%); Its most common partners include Invoked Mechaba (83.2%), Raidjin (80.4%), and Augoeides (75.5%)
• Inferred: It functions as a conditional extender that changes which Invoked Fusion sits on board rather than starting a combo; Being a Quick-Play Spell allows reactive activation on a later turn if the Invoked body survives; The trade of one Invoked body for another is card-neutral and generates no advantage by itself
• Data gaps: no combos supplied — combo conversion is text-only inference no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
