Fusion Reserve — Power Evaluation
Final Score: 61 ± 8 · Confidence: Medium
- Intrinsic: 59 · Deck: 63 · Meta: provisional
- Primary role: Searcher/Tutor
Why it scores here
Fusion Reserve is a Normal Trap whose value is search: it adds one listed Fusion Material from the Deck to hand and can then add Polymerization from the Graveyard, so it converts a live Fusion Monster in the Extra Deck into a summon-ready line. The 151-deck sample shows it is run by 31 archetypes at a 1.28 average copy count, with Polymerization in 84.8% of those decks, which supports a real, practical Searcher role. High ATK or rarity earned nothing here; the score is limited by its Fusion dependence, by the absence of combo evidence, and by its lack of any opponent interaction or body.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 78 | Searches a Fusion Material from the Deck and can recover Polymerization from the Graveyard, with 151 of 151 decks running it (observed). |
| Combo & Conversion | 62 | Its text enables a Fusion summon from a Fusion Monster in the Extra Deck, but no combo boards were supplied, so conversion is text-only inference (inferred). |
| Resource Economy | 70 | Trap cost is offset by a Deck search and a possible Graveyard recovery, giving at most a net +1 card (inferred from text). |
| Effect & Interaction | 5 | No negation, removal or disruption is printed on the card (verified). |
| Material Utility | 5 | A Trap is not a monster body and cannot be used as Fusion or Link material (verified from card frame trap). |
| Resilience & Flexibility | 40 | A single set Trap in the Spell/Trap zone can be stopped by one answer to its search, and it has no redundancy in the printed text (inferred). |
| Deck-Building Efficiency | 70 | A single non-garnet trap slot with 1 to 3 copies per deck and no locking restriction (observed from copies per deck). |
Calculation
Weight profile: Pure Searcher/Tutor profile, no secondary blend. Intrinsic ≈ 59, Deck ≈ 63, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts a Fusion Monster in the Extra Deck into a summon-ready Fusion Material from the Deck
- Graveyard recovery of Polymerization adds a second recovery route
- Runs in 31 archetypes across four gameplays, so it is not tied to one home
- Cheap to run: single trap slot, no garnet or lock restriction
Weaknesses
- Requires a Fusion Monster in the Extra Deck to be useful at all
- Does not add a body, negate anything or affect the board by itself
- Set-then-activate timing gives the opponent a window to answer the search
- Combo contribution is unmeasured because no combo boards were supplied
Counters / choke points
- Search-negating responses to the Deck-to-hand add
- Opponent-side disruption before the Fusion summon resolves
Best use
Searcher/Tutor for Fusion lines, paired with Polymerization and Super Polymerization. Decks: Blue-Eyes, Prank-Kids, Branded, Gate Guardian, Dark Magician, Red-Eyes, Kashtira. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: reveals a Fusion Monster in the Extra Deck, adds a listed Fusion Material from the Deck, then optionally adds Polymerization from the Graveyard; Trap card, Normal race, all four formats legal; 151 of 151 decks run it; 1.28 average copies per deck
- Observed: Polymerization appears in 84.8% of decks that run Fusion Reserve; Archetype and gameplay spread: 31 archetypes, gameplay 7 at 72.8%
- Inferred: The search is a net +1 card at best, counting the Trap cost; Set-then-activate timing exposes the search to one answer
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion % is from the deck sample only
