Stream, Dragon Ruler of Droplets — Power Evaluation
Final Score: 55 ± 8 · Confidence: Medium
- Intrinsic: 51.8 · Deck: 56.4 · Meta: provisional
- Primary role: Starter / Combo enabler · Secondary: Extender
Why it scores here
Stream's value is a single conversion: it costs itself plus one Dragon or WATER monster and Special Summons Tidal from the Deck, which is a body but not a board on its own. It is present in all 400 sampled decks at about 1.5 copies each, and Tidal co-occurs in 100% of them, which confirms it is a live, practical engine piece. That frequency reflects the Dragon Ruler engine it belongs to rather than intrinsic power, so the 1600 ATK and the Level 4 body earn no points; there is no combo or interaction evidence to lift the score further.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Live in 400/400 sampled decks at about 1.5 copies each, but it needs a second Dragon or WATER monster to pay its cost (text plus deck stat, verified/observed). |
| Combo & Conversion | 45 | Converts two cards into one Deck-sourced body, Tidal, and the text grants no further board; no combo examples are supplied (text-only inference). |
| Resource Economy | 40 | Net hand card change is -1 (two hand cards discarded, one Deck card summoned); no GY refuel or searches are stated in the text (verified/inferred). |
| Effect & Interaction | 5 | The text has no negation, removal or hand-trap effect, so it offers no opponent interaction (verified). |
| Material Utility | 35 | A Level 4 WATER Dragon body, but its own effect discards it, so it is rarely on the field as material; no material evidence is supplied (inferred). |
| Resilience & Flexibility | 50 | Hand-cost once-per-turn effect with no stated protection; it is spread across the Dragon Ruler family's shared fodder, so redundancy is moderate (inferred). |
| Deck-Building Efficiency | 70 | Averages about 1.5 copies with max 3, needs only generic Dragon or WATER fodder, and carries no garnet or lock clause in the text (verified/observed). |
Calculation
Weight profile: 0.7 Starter/Combo enabler + 0.3 Extender. Intrinsic ≈ 51.8, Deck ≈ 56.4, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Deck-to-field Special Summon of Tidal, a practical body for the Dragon Ruler engine
- Present in every sampled deck at low copy counts, so the card is consistently accessible
- Cheap to run with generic Dragon or WATER fodder and no garnet clause
Weaknesses
- Costs two cards for one body, so it is a net card-disadvantage on its own
- No opponent interaction, negation, or removal
- No combo evidence, so its real conversion rate is unknown
Counters / choke points
- Hand traps or negation that stop the hand-cost activation, if the card is activated from hand (inferred; location not stated in the text)
Best use
Deck-to-field Tidal enabler inside the Dragon Ruler engine. Decks: Dragon Ruler, Armed Dragon, Rose Dragon, Tenpai Dragon.
Evidence & gaps
- Verified: Level 4 WATER Dragon Effect Monster, 1600 ATK / 2000 DEF (card fields); Discard this card and 1 Dragon or WATER monster to Special Summon Tidal from the Deck; can't attack this turn; once per turn (card text); Present in 400/400 sampled decks; Tidal co-occurs in 100% of them; average 1.47 copies (deck data)
- Observed: Usage statistics: 100% inclusion in Amorphage, 66.7% in Dragon Ruler (gameplay 4), 42.9% in Dragon Ruler (gameplay 7) (usage statistics); Gameplay split: MasterDuel 93.8%, two smaller gameplays (deck data); Two guides mention it as an extender in Dragon Ruler and Armed Dragon lines (guide data)
- Inferred: Primary role is a starter/enabler rather than a searcher, because it is a Deck-to-field summon that is not a search; The activation location is not stated in the text; the discard-cost wording suggests a hand activation; Dragon Ruler family membership comes from the card name; the archetype field is null
- Data gaps: No combos supplied: combo conversion is text-only inference Activation location (hand/GY) is not stated in the description Archetype field is null despite the Dragon Ruler name No banlist token; assumed 3 copies (unlimited)
