Valiant Shark Lancer

Valiant Shark Lancer — Power Evaluation

Final Score: 58 ± 6 · Confidence: Medium

• Intrinsic: 56.3 · Deck: 57 · Meta: provisional
• Primary role: Boss/End-board · Secondary: Removal/Negation, Material body

Why it scores here

Valiant Shark Lancer converts two Level 5 bodies into a 2500-ATK Rank 5 board piece that repeatedly targets and destroys an opponent's monster, upgrades that to a Quick Effect while another WATER Xyz is on board, and slowly re-stacks a Spell on top of the Deck when a second WATER Xyz dies. That is a real but narrow payoff: it is a one-of end-board/removal card in Shark decks (400 lists, avg 1.01 copies, with Abyss Shark at 87% and Crystal Shark at 83.8% co-deck rate), not a starter, extender, or advantage engine, and the sample contains zero recorded combo boards. Its 2500 ATK and Rank 5 are not why it scores here - the material cost of 2 Level 5 monsters, the Xyz-material cost of each destruction, and the missing combo evidence keep it in the mid-50s.

Axis scores

Calculation

Weight profile: 0.7 Boss/End-board + 0.3 Removal/Negation. Intrinsic ≈ 56.3, Deck ≈ 57, Meta = provisional. Modifiers: Compact 1-of slot (1). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Repeatable targeted destruction of an opponent's monster, once per turn, usable on the opponent's turn as a Quick Effect while another WATER Xyz is controlled.
• Fits naturally into Shark decks, where Abyss Shark and Crystal Shark (both Level 5) provide the two materials at high co-deck rates (87% / 83.8%).
• Clean one-of slot (avg 1.01 copies; 395/400 decks run exactly 1) with no lock, no garnet and no Extra Deck tax.
• Doubles as a Rank 5 WATER Xyz material for Full-Armored Xyz / N.As.H. Knight lines even if its effect is negated.
• Second effect slowly re-stacks a Spell from Deck to the top, providing a soft follow-up resource after a WATER Xyz is destroyed.

Weaknesses

• Requires 2 Level 5 monsters, so it is never live off a single card and is slow compared to Rank 4 Shark plays.
• Each destruction consumes an Xyz material, so the removal is finite and cannot be looped.
• The Quick Effect upgrade is conditional on controlling a second WATER Xyz, which is easy to strip with interaction.
• No combo evidence in the sample - its practical ceiling is inferred from text and deck lists only.
• Only one Spell-stacking use per turn, and only when another WATER Xyz you control is destroyed.

Counters / choke points

• Monsters that cannot be targeted or destroyed by card effects blank the destruction effect.
• Effect negation such as Infinite Impermanence stops the destruction before the material is detached.
• Removing or negating the second WATER Xyz denies the Quick Effect timing window.
• Hand disruption aimed at Abyss Shark / Crystal Shark lines delays the two Level 5 materials it needs.

Best use

Rank 5 removal / end-board piece and Full-Armored Xyz material. Decks: Shark, Umi. Suggested copies: 1.

Evidence & gaps

• Verified: Card text: must be Xyz Summoned with 2 Level 5 monsters.; Card text: detach 1 material from an Xyz Monster you control to destroy a targeted opponent's monster; this becomes a Quick Effect while you control another WATER Xyz Monster.; Card text: if another WATER Xyz Monster you control is destroyed by battle or card effect, you can take 1 Spell from your Deck and place it on top of your Deck.; Card text: each effect can only be used once per turn.; 400 decks run it, all in the main deck, average 1.01 copies (395 decks with 1, 5 decks with 2).
• Observed: Shark-family archetypes account for roughly 71% of the 400 decks running it.; Top partners are Abyss Shark (87%), Crystal Shark (83.8%) and Buzzsaw Shark (81.8%).; It co-occurs with Full-Armored Xyz (64.2%), Full Armored Dark Knight Lancer (63.5%), N.As.H. Knight (63%) and Xyz Armor Fortress (63%).; Usage statistics record 100% inclusion at 1 typical copy within the Shark archetype sample.; The single guide mentioning it files it under a 'Techs' section of a Shark Kragen build.
• Inferred: The two Level 5 materials are normally supplied by Abyss Shark and Crystal Shark in Shark decks.; It functions as material inside Full-Armored Xyz / N.As.H. Knight upgrade lines given the co-deck rates.; Because zero combos were recorded, its combo role is inferred from text alone rather than measured.; Its removal ceiling is bounded by the number of Xyz materials available at the time of activation.
• Data gaps: no combos supplied - combo conversion is text-only inference no banlist token - assumed 3 copies (unlimited) average starter count when present and average power index when present are null, so deck resilience could not be measured directly archetype names are duplicated across several ids (multiple 'Shark' entries), so distinct archetypes overstates true deck diversity
