Snowman Effect

Snowman Effect — Power Evaluation

Final Score: 29 ± 8 · Confidence: Medium

• Intrinsic: 30 · Deck: 30 · Meta: provisional
• Primary role: Utility

Why it scores here

Snowman Effect is a Normal Trap combat trick that converts only into a one-turn ATK boost on one of your own face-up monsters, and it even forbids that monster from attacking directly. It builds no board, offers no interaction with the opponent, and is a pure minus-one in card economy, with zero recorded combo appearances across the sampled boards. Its only real credit is that it is fully generic and cheap to slot — 37 decks run it as a 1-of across 10 archetypes — which keeps it off the absolute floor rather than lifting it into a playable band. The high-ish co-occurrence counts (Evenly Matched, Monster Reborn, generic staples) confirm accessibility, not power, and earn nothing here.

Axis scores

Calculation

Weight profile: Utility / no clear role (default) profile. Intrinsic ≈ 30, Deck ≈ 30, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Fully generic Normal Trap with no archetype restriction, so it can be slotted into any deck
• Cheap to run: a clean 1-of with no garnet, no lock and no extra engine required
• Can steal a battle by boosting a monster's ATK to run over a bigger opposing body

Weaknesses

• Pure minus-one: spends a card for a temporary ATK boost with no card advantage
• Provides zero interaction with the opponent — no negation, removal or disruption
• Requires an established board with at least one other monster to gain any ATK at all
• The boosted monster cannot attack directly the turn it is used, blunting its own payoff
• A Normal Trap is slow and dies to a single Spell/Trap negation or backrow removal
• No combo presence whatsoever across the sampled boards

Counters / choke points

• Spell/Trap negation (e.g. Solemn Judgment, Cosmic Cyclone, Harpie's Feather Duster)
• Removing the targeted monster before or in response
• Boards with only one monster, where the boost gains nothing
• Matchups where the opponent never commits to battle

Best use

Battle trick / ATK-boost utility. Suggested copies: 1.

Evidence & gaps

• Verified: Card text: Trap Card that targets 1 face-up monster you control and grants it ATK equal to the combined original ATK of your other monsters until the end of the turn; Card text: the boosted monster cannot attack directly during the turn this card is activated; Card text: only 1 'Snowman Effect' can be activated per turn; Card text: provides no negation, removal or opponent interaction
• Observed: 37 sample decks run Snowman Effect, all in the main deck, at exactly 1 copy each; Spread across 10 distinct archetypes with generic top partners (Evenly Matched 78.4%, Monster Reborn 73%, Reinforcement of the Army 73%); 0 combo appearances and 0 board appearances across the recorded combo sample; No guides mention the card and no usage statistics rows exist
• Inferred: It is a win-more battle trick: it needs an established board of two or more monsters to produce a meaningful ATK gain; Its generic text is why it appears in many unrelated archetypes, not any real synergy; It converts a board state into a battle win, not into a new board or interaction
• 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 deck sample is small (37) and its archetype co-occurrence may be noisy
