Buster Gundil the Cubic Behemoth — Power Evaluation

Final Score: 48 ± 8 · Confidence: Medium

  • Intrinsic: 49 · Deck: 47 · Meta: provisional
  • Primary role: Boss/End-board · Secondary: Recovery/Recursion

Why it scores here

Buster Gundil is a Cubic-only Special Summon that must send 3 Cubic monsters you control to the Graveyard from your hand, so it is only as live as the Cubic board that feeds it. Once out it becomes a 3000-ATK body with three battle attacks, which is the end-board conversion the score credits. Its Graveyard trigger (revive up to 3 Cubic and add a Cubic) adds some recovery, but the card has no negation or removal and only runs in Cubic-shaped decks, so the 3000 ATK and the 234-deck count earn little on their own.

Axis scores

Axis Score Evidence
Accessibility 68 Summoning needs 3 Cubic you control to send to the GY, so it is live only on a Cubic board; it appears in 234 sampled decks, 61.5% in the main Cubic archetype (observed).
Combo & Conversion 72 The text gives 3000 ATK and up to three attacks per Battle Phase, so it converts a Cubic board into a large end-board; no combo boards were recorded to confirm this (inferred).
Resource Economy 60 The Graveyard trigger revives up to 3 Cubic and adds 1 Cubic when the card is sent to the GY by an opponent's card, a real but conditional card gain (verified text).
Effect & Interaction 15 The card has no negation, removal, or hand-trap effect; its only opponent-triggered effect is a recursion trigger (verified text).
Material Utility 30 It is a Level 4 LIGHT Beast body with no clean material role stated, and its summon cost consumes Cubic monsters rather than providing material (inferred).
Resilience & Flexibility 50 The Graveyard trigger lets it recover value after the opponent's removal, but it cannot be Special Summoned from the Graveyard or any other zone (verified text).
Deck-Building Efficiency 45 It runs 1 copy in 212 of 234 decks and is a Cubic-only restriction that locks it into Cubic homes; no garnet data is supplied (observed).

Calculation

Weight profile: 0.7 Boss/End-board + 0.3 Recovery/Recursion. Intrinsic ≈ 49, Deck ≈ 47, Meta = provisional. Modifiers: Self-locking restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Converts a Cubic board into a 3000-ATK, three-attack end-board
  • Graveyard trigger recovers up to 3 Cubic and adds 1 Cubic when an opponent's card sends it to the GY
  • Consistently included in its home archetype (57% inclusion, 1 copy typical)

Weaknesses

  • Summon condition requires a live Cubic board, with no stated route from the hand alone
  • No negation, removal, or hand-trap effect
  • Its Graveyard trigger needs opponent interaction and targets, so it does nothing if the card is not sent to the GY

Counters / choke points

  • Opponent card-based removal that sends it to the GY before it can be summoned, with no effect on a summon already made
  • Negation or banishment of the Cubic monsters that feed the summon

Best use

Boss/End-board finisher in Cubic. Decks: Cubic (archetype 706), Cubic Tearlaments Fiendsmith. Suggested copies: 1.

Evidence & gaps

  • Verified: Summon condition: Special Summoned from hand by sending 3 Cubic you control to the GY; cannot be Special Summoned by other ways; Gains 3000 ATK when summoned this way; can attack up to three times per Battle Phase; Graveyard trigger: Special Summon up to 3 Cubic from the GY, then add 1 Cubic card from Deck or GY to hand; Level 4, LIGHT, Beast, Cubic archetype
  • Observed: 234 sampled decks contain the card; 61.5% are in the main Cubic archetype (706); Inclusion 57.1% in the Cubic archetype (gameplay type 7), typical 1 copy; 212 of 234 decks run 1 copy
  • Inferred: Its strength depends on a live Cubic board that can feed the summon; It acts as a finisher rather than a material body
  • Data gaps: No combos supplied: combo conversion is text-only inference No banlist token supplied; assumed 3 copies (unlimited) Deck sample is conditioned on the card being present, so deck synergy has no baseline comparison No rulings or garnet/brick data supplied
