Plan Coherence evidence
Method: weighted theme and role scores · aggro
Weighted score inputs: Synergy 100 · Draw 100 · Interaction 91.7 · Win pieces 100 · Combo 100 (each /100)
Off-theme role cards: 14.3% of nonland copies · Construct-adjusted share: 11.1% of nonland copies (not used by the weighted method)
- Stabilized plan score: synergy already carries the role-soup penalty, so the primary read avoids the legacy double-penalty.
Foundation watchlist
Base vs commander
Foundation is healthy enough to support commander tuning.
Concrete closers are visible alongside the value plan.
Opening composition v2 · exact 7-card draws from 99 cards · 36 playable land faces (0 draft-only sources excluded) · 23 spells at mana value 0–2 · 17 ramp-tagged and 5 draw-tagged cards at mana value 0–3. Spell costs recorded for 63/63; missing mana values 0 (assumed 3), types 0, land text 0, nonland text 0. Land policy playable-land-faces-v1; front lands and verified modal land choices count, conditional transform backs do not. Multi-face cards 1 retain combined metadata for other estimates; invalid quantity rows excluded 0. Mana colors, tapped lands, activation costs, spending restrictions, draw conditions, multi-face availability and mulligans are not simulated.
Deck Strategy
This deck plays as a tribal-aggro shell with layered lines and flexible pivots.
In the early game, set up mana and hand quality before committing key threats. Midgame plans should build board presence through synergistic engines and incremental pressure. Your late-game priority is to outlast opponents through resilient threats and card advantage.
Strategy Graph
Tribal-Aggro: Theft Value Engine into Theft Value Snowball.
unfocused - Based on the strongest recognized support, the list is spreading support across Tokens, Control, Theft, so the graph is less confident about a single main plan.
Counter support is unverified
2 matched card copies × 0.1 + 0 archetype bonus, capped at 1 = 0.20 candidate score. This is a heuristic score, not a win probability.
Core eligibility: four-copy threshold not met; commander heuristic not matched; archetype not matched. These inputs do not admit a counter core.
Matches can include placement, spending, opponent-directed effects and resource counters. Own growth, compatible recipients, repeatability and a finishing route need separate evidence.
counter-support-v1
Artifact Engine Commander
Prosper, Tome-Bound turns artifacts or Treasures into mana, cards, combo material, or scalable board pressure.
Theft Value Engine
The deck converts opponents' cards and permanents into flexible value, often reusing enter-the-battlefield theft effects for advantage.
Death/Drain Payoffs
Life-drain and death-trigger payoffs convert engine loops into table pressure.
Theft Value Snowball
Candidate plan inferred from the cards shown; required setup and effectiveness are not verified.
Plan A: Theft Value Snowball
Plan A wants to turn opponents' libraries or permanents into resources and snowball from their strongest cards.
Plan B: Cascade/Impulse Chain
This pivot can chain cascade, discover, or cast-from-exile effects into enough spell volume to overwhelm the table.
Fallback: Value Pressure
If the clean finish is not available, the deck should still convert its engine into pressure through this backup route.
Open Opponents' Cards
Set up access to opponents' cards or permanents before investing in repeat-value pieces.
Turn On The Engine
The deck converts opponents' cards and permanents into flexible value, often reusing enter-the-battlefield theft effects for advantage.
Convert Into Payoff
Use the engine to generate pressure, cards, mana, or attrition that changes the table state.
Close The Game
Finish through Theft Value Snowball.
Functional But Unfocused
The deck has meaningful support for Tokens, Control, Theft, but no single package clearly owns the plan.
Typal Label Needs Type Density
The archetype says typal, but type-specific lords, token makers, or payoff cards are too sparse.
Token Payoffs
The deck can make bodies, but it needs anthem, draw, sacrifice, or drain payoffs that turn a wide board into a win.
Typal Density
Typal decks need enough type-specific lords, token makers, or payoff cards to be more than a normal creature deck.
