Thunder Crash

Thunder Crash — Power Evaluation

Final Score: 34 ± 7 · Confidence: Medium

• Intrinsic: 32 · Deck: 36 · Meta: provisional
• Primary role: Utility · Secondary: Material body, Combo enabler

Why it scores here

Thunder Crash is a generic Normal Spell whose only function is to destroy every monster you control and then burn the opponent for 300 per monster destroyed — at most a small, self-inflicted board wipe plus chip damage. It advances no board state on its own and gives the opponent nothing to answer, so it earns its points mainly from being a cheap, restriction-free one-of rather than from any offensive output. Its observed presence in 26 recent decks (avg 1.31 copies, 9 archetypes, heavily clustered around Exodia deep-draw shells) confirms it is a real but narrow utility slot, not a power card. High burn numbers or any perceived 'damage' value did not earn points here: the card is scored on how little it converts and how badly it needs an already-developed own board to function.

Axis scores

Calculation

Weight profile: 0.7 Utility (default, no clear role) + 0.3 Material body. Intrinsic ≈ 32, Deck ≈ 36, Meta = provisional. Modifiers: Narrow niche usage (-2). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Fully generic Normal Spell with no cost, no archetype lock, and no once-per-turn restriction
• Burn output scales with your own board size (300 per monster destroyed)
• Can clear your own board to trigger 'when destroyed' effects or free zones for later plays
• Cheap to include: a single slot, no garnet, unlimited copies available

Weaknesses

• Does nothing without an existing board of your own monsters
• Gives up your own field presence for a small amount of burn damage
• Provides zero interaction with the opponent's board, hand, or Graveyard
• Maximum realistic damage is low and rarely converts into a win by itself
• One-shot Spell with no Graveyard recursion or multi-turn value in its own text

Counters / choke points

• Effect negation such as Solemn Judgment or Solemn Strike blanks it
• Having no monsters on field makes the card functionally dead
• Opponent can simply play into the smaller board you leave behind
• Ash Blossom & Joyous Spring does not stop it, but generic Spell/Trap removal on your burn setup does

Best use

Self-board-clearing burn finisher / utility one-of. Decks: Exodia deep-draw FTK shells, Flamvell, Self-destruct / burn-focused combo builds. Suggested copies: 1.

Evidence & gaps

• Verified: Card text: 'Destroy all monsters you control, and if you do, inflict 300 damage to your opponent for each monster destroyed.'; Card is a Normal Spell with no archetype, no cost, and no once-per-turn clause.; Appears in 26 of the sampled recent decks, 26 in main deck and 0 in side, average 1.31 copies (22 lists at 1 copy, 4 at 3).; No combo entries record this card (total combos = 0, appearances = 0).
• Observed: Spread across 9 distinct archetypes but concentrated in Flamvell (6 decks), Greed (6), and Exodia (6).; Co-appears with Exodia limbs, Wonder Wand, Treasure Panda, Summoner Monk, Into the Void and Magical Mallet in 69.2% of its decks.; Co-appears with Number 60: Dugares the Timeless in 76.9% and Stardust Charge Warrior in 73.1% of its decks.
• Inferred: Because the card only affects your own monsters, it is used as a self-board-clear or burn finisher inside a set-up draw/combo shell, not as interaction.; With an empty or protected field the card resolves for no destruction and no damage, making it a dead card in those spots.; Destroying your own monsters can be used to trigger 'when this card is destroyed' effects or to free zones.
• Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no metagame sample, so meta power is provisional/null
