Eisbahn — Power Evaluation
Final Score: 51 ± 8 · Confidence: Medium
- Intrinsic: 49 · Deck: 52 · Meta: provisional
- Primary role: Floodgate/Control
Why it scores here
Eisbahn is a continuous trap with no ATK, DEF, or body, so none of its score comes from stats. It converts any non-WATER monster that is Normal or Special Summoned into Defense Position, but only while its controller also controls a WATER monster, so its value depends on the WATER board. The card is run in all 41 sampled decks (1.68 average copies), which confirms it is a live, cheap, practical slot in WATER shells, but that frequency is not counted as power. With no combo or guide evidence, its score rests on the text and deck usage alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | Run in 41 of 41 sampled decks at 1.68 average copies, but no searcher or combo-start evidence was supplied, so access is inferred from deck inclusion (observed). |
| Combo & Conversion | 15 | No combo boards were supplied and the card only restricts summons; it builds no board of its own (inferred). |
| Resource Economy | 10 | No card advantage, refuel, or cost return is described in the text (verified). |
| Effect & Interaction | 45 | Soft, conditional summon control: it changes the position of non-WATER summons only while a WATER monster is controlled, and does not touch effects (verified text, inferred strength). |
| Material Utility | 0 | A continuous trap has no monster body and cannot be used as material (verified). |
| Resilience & Flexibility | 50 | Stays on the field across turns once active, but depends on the WATER monster remaining and on the card surviving interaction (inferred). |
| Deck-Building Efficiency | 70 | Low-cost, non-garnet slot in WATER decks, averaging under two copies with no self-restriction in the text (observed plus verified text). |
Calculation
Weight profile: Floodgate/Control primary; no secondary role blended. Intrinsic ≈ 49, Deck ≈ 52, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap, non-garnet slot that shows up in 41 of 41 sampled decks
- Persistent position control over non-WATER summons for multiple turns
- Works against both players' summons, so it is not limited to one side
Weaknesses
- Only active while you control a WATER monster
- Covers Normal and Special Summons only, not effects or other board actions
- No combo, card advantage, or material value
Counters / choke points
- Opponent's WATER-free board or non-summon plays (inferred)
- Removal or disruption of your own WATER monster switches it off (inferred)
Best use
Floodgate against non-WATER summons in WATER decks. Decks: Ice Barrier (614, 443, 247), Harpie (493, 256), Icejade (1319), Centur-Ion (1558). Suggested copies: 1.
Evidence & gaps
- Verified: Continuous trap text: non-WATER Normal/Special Summons changed to Defense Position while controlling a WATER monster; Run in 41 decks at 1.68 average copies, 25 distinct archetypes; Top partners at 58–78% co-deck rates
- Observed: Present in all 41 sampled decks, mostly in Ice Barrier builds; No combo appearances recorded
- Inferred: Floodgate/Control role from the continuous summon-position effect; Practical value depends on the WATER board, so it is weak outside WATER shells
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no rulings for continuous trap activation timing or interaction with Special Summon chains no banlist token — assumed 3 copies (unlimited)
