Each time an opponent's monster declares a direct attack: You can excavate the top card of your Deck, and if it is a Plant-Type monster, send it to the Graveyard. Otherwise, place it on the bottom of your Deck. During your Draw Phase, instead of conducting your normal draw: Excavate the top card of your Deck, and if it is a Plant-Type monster, send it to the Graveyard. Otherwise, add it to your hand.
Sylvan Waterslide — Power Evaluation
Final Score: 37 ± 6 · Confidence: Medium
- Intrinsic: 36 · Deck: 38 · Meta: provisional
- Primary role: Utility · Secondary: Combo enabler
Why it scores here
Sylvan Waterslide is a slow Continuous Trap that converts Deck top-decking into Plant-Graveyard setup: on its Draw Phase replacement it excavates and mills a Plant-Type or adds a non-Plant to hand, and on an opponent's direct attack it does the same mill. That makes it a genuine consistency/mill engine for Plant decks such as Sylvans, Rikka, Naturia and Rose Dragon, but it provides no interaction with the opponent and no board on its own, so its practical value is incremental. Its 0 ATK/DEF and trap status earn nothing here — the score reflects that it is a cheap, low-redundancy role-player whose payoff is measured and slow rather than explosive. It sees play in 15 sampled decks at ~1.13 copies, confirming the role is real but niche.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | It is a Continuous Trap with no listed searcher route and no combo evidence of it being searched, so it is largely a draw-it-or-not card (verified text; inferred). |
| Combo & Conversion | 25 | No combo data appearances (0) and the effects only filter/mill one card per Draw Phase, building no board by itself (observed: 0 appearances). |
| Resource Economy | 40 | The Draw Phase replacement is roughly even — a non-Plant goes to hand like a normal draw, while a Plant is milled instead, so it is neutral-to-slightly-positive rather than true card advantage (inferred). |
| Effect & Interaction | 10 | It offers zero disruption or removal; the direct-attack trigger only excavates and never negates, destroys, or removes the attacker (verified text). |
| Material Utility | 5 | As a Trap it cannot be used as material, an Xyz/Fusion/Synchro body, or a name/level provider (verified text). |
| Resilience & Flexibility | 35 | It persists across turns on the field, but is a single Continuous Trap card exposed to backrow removal and only fires on your Draw Phase or an opponent's direct attack (inferred). |
| Deck-Building Efficiency | 45 | It is run at ~1.13 copies with max 2, is not a garnet, and asks for only one slot, but demands a Plant-heavy deck to matter (observed: copies per deck avg 1.13). |
Calculation
Weight profile: 0.7 Utility + 0.3 Combo enabler. Intrinsic ≈ 36, Deck ≈ 38, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Persistent excavate engine that seeds the Graveyard with Plant-Type monsters for Sylvan and other Plant strategies
- Dual effect: Draw Phase replacement improves consistency, and the direct-attack trigger adds extra mills
- Archetype-agnostic within Plant decks, shows up across Sylvans, Sylvan, Rikka, Naturia, Rose Dragon and Neo-Spacian builds
- Low opportunity cost — typically a single copy, no garnet and no self-lock
Weaknesses
- Extremely slow: value only accrues once per Draw Phase and reactively on opponent direct attacks
- Provides no interaction, removal, negation or board presence
- Not searchable by any listed route, so it is unreliable to open
- Dead card in any non-Plant deck and in games where it cannot reach the field early
- Continuous Trap is vulnerable to backrow removal before it can accrue value
Counters / choke points
- Backrow removal such as Cosmic Cyclone or Twin Twisters strips it before it accrues value
- Preventing direct attacks denies the excavate trigger entirely
- Trap negation (e.g. a Counter Trap or trap-negating effect) on activation
- Negating or overriding the Draw Phase replacement effect via card effects that change the draw
Best use
Plant Deck mill / consistency engine. Decks: Sylvans, Sylvan, Rikka, Naturia, Rose Dragon. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: each time an opponent's monster declares a direct attack, excavate the top card and mill it if it is a Plant-Type, otherwise place it on the bottom of the Deck; Card text: during your Draw Phase, instead of a normal draw, excavate the top card and mill it if it is a Plant-Type, otherwise add it to your hand; Card type is Continuous Trap; ATK/DEF are 0/0; archetype is Sylvan; legal in TCG, OCG, MasterDuel and DuelLinks
- Observed: 15 total decks run it, all in the main deck, average 1.13 copies (13 decks at 1 copy, 2 decks at 2 copies); 6 distinct archetypes across the sample, led by Neo-Spacian, Naturia and Rikka at 20% each; Top partners: Orea, the Sylvan High Arbiter (100%), Aromaseraphy Jasmine (93.3%), Called by the Grave and Benghalancer the Resurgent (86.7%); 0 combo data appearances across recorded boards
- Inferred: The card acts as a Plant-focused Graveyard setup/consistency engine rather than a board builder; The Draw Phase replacement is roughly card-neutral, effectively a draw that may instead mill a Plant; It offers no interaction with the opponent and cannot be used as material because it is a Trap
- Data gaps: no combos supplied — combo conversion is text-only inference no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no board/power index data to measure its real contribution in Plant end-boards
