Commander profile

Written by the model in one profile_synthesis call from the commander's card text and the evidence below. Identity, set and timestamps come from trusted inputs, not the model.

Exile-to-cast value engine with Treasure synergy

Prosper generates card advantage by exiling the top card each end step and allowing you to play it until your next turn. Each time you play a card from exile, you create a Treasure token, which ramps you and fuels further plays. The deck aims to maximize the number of cards played from exile each turn, using Treasure synergies to convert those tokens into damage or card draw. The commander's deathtouch provides a defensive deterrent, but the primary strategy is value accumulation and explosive turns.

Win conditions the profile proposes

"in deck" marks profile key cards that made the final list. Others were cut by budget, legality, or optimization.

Build paths the profile describes
  • Treasure Burn (mainstream): Focus on generating as many Treasures as possible and using pingers like Reckless Fireweaver and Mayhem Devil to drain opponents. Includes token doublers and sacrifice outlets.
  • Exile Value Midrange (mainstream): Maximize the number of cards played from exile each turn using impulse draw effects and cards that care about exile. Use value creatures to out-grind opponents.
  • Treasure Combo (emerging): Use Academy Manufactor and Xorn to generate massive token counts, then win with token-based combos or massive burn. Includes untap effects and cost reducers.
Rest of the strategic profile
Synergy priorities
high: ['Cards that can be played from exile', 'Treasure token generators', 'Token synergy pingers (e.g., Reckless Fireweaver)', 'Cards that care about exile (e.g., Laelia, the Blade Reforged)']; medium: ['Ramp and mana rocks', 'Card draw and filtering', 'Removal and interaction', 'Creatures with attack triggers (e.g., Etali, Primal Storm)']; low: ['Graveyard recursion', 'Counterspells (not in color identity)', 'Life gain']
Anti synergies
description: Cards that exile cards from your library but don't allow you to play them (e.g., 'exile target card from graveyard' effects) don't trigger Prosper's second ability., cards_to_avoid: ['Surgical Extraction', 'Extirpate'], reasoning: These cards exile cards but don't let you play them, so they don't create Treasures or advance the exile-to-cast plan.; description: Cards that shuffle your library or put cards from exile into your hand can disrupt the exile-to-cast timing., cards_to_avoid: ['Pull from Eternity', 'Riftsweeper'], reasoning: These cards remove cards from exile, potentially losing the opportunity to play them and missing Treasure triggers.; description: High-cost spells that can't be cast from exile efficiently may be dead draws if you can't ramp quickly., cards_to_avoid: ['Blasphemous Act', 'Peer into the Abyss'], reasoning: While these are powerful, they don't synergize with the exile-to-cast engine and may sit in hand if you can't generate enough mana.
Strategic constraints
mana_base_requirements: Need consistent access to both black and red mana early; include dual lands and ramp to cast Prosper on turn 3-4.; interaction_density: medium; speed_tier: midrange
Power indicators
estimated_ceiling_bracket: 4; estimated_floor_bracket: 3; notes: Prosper can be built as a high-value engine with consistent Treasure generation, but lacks a built-in combo finish. Ceiling is high with efficient exile-matters cards; floor is still solid due to card advantage and ramp.
Value inversions
normal_heuristic: Cards that exile themselves or other cards are often seen as risky or card disadvantage., inverted_value: Prosper rewards playing cards from exile, so self-exiling effects become card advantage and Treasure generation., desired_characteristics: ["Cards with 'exile' in their text", 'Impulse draw effects', 'Cards that can be cast from exile'], undesired_characteristics: ['Cards that shuffle exile back into library', 'Cards that remove cards from exile without playing them'], evaluation_guidance: When evaluating cards, prioritize those that can be played from exile or that exile cards for later use. Cards that exile for no benefit are still low value.; normal_heuristic: Treasure tokens are usually just mana acceleration, not a win condition., inverted_value: Prosper creates Treasures as a byproduct of playing from exile, and cards like Reckless Fireweaver turn each Treasure into damage, making token generation a primary win path., desired_characteristics: ['Treasure token generators', 'Token synergy pingers', 'Sacrifice outlets'], undesired_characteristics: ['Cards that sacrifice Treasures for one-time effects without other synergy'], evaluation_guidance: Value cards that multiply Treasure generation or convert Treasures into damage/draw. Single-use Treasure sacrifice is less impactful.
Engine dependencies
engine: Playing cards from exile, engine_card_traits: ["Cards with 'exile' in their text", 'Impulse draw effects', 'Cards that can be cast from exile'], dependent_outputs: ['Treasure tokens', 'Card advantage', 'Ramp'], false_synergy_warning: Cards that exile cards but don't allow you to play them (e.g., 'exile target card from graveyard') don't trigger Prosper's second ability and are traps.; engine: Treasure token generation, engine_card_traits: ['Cards that create Treasure tokens', 'Token doublers', 'Cards that care about artifacts'], dependent_outputs: ['Mana acceleration', 'Burn damage via pingers', 'Sacrifice fodder'], false_synergy_warning: Cards that just care about artifacts but don't generate Treasures or play from exile may not advance the engine. For example, 'Affinity for artifacts' cards don't help Prosper's specific plan.
Mispriced card examples
card_name: Xorn, why_undervalued: A 3-mana 2/2 that doubles Treasure generation, which is a massive multiplier for Prosper's engine.; card_name: Academy Manufactor, why_undervalued: Turns each Treasure into a Clue and Food as well, tripling token output and enabling draw and life gain.; card_name: Reckless Fireweaver, why_undervalued: A 1/3 for 3 that deals 1 damage whenever an artifact enters, turning every Treasure into a burn spell.; card_name: Mayhem Devil, why_undervalued: A 3-mana 3/3 that pings whenever a permanent is sacrificed, synergizing with Treasure sacrifice.; card_name: Laelia, the Blade Reforged, why_undervalued: A 2/2 that grows with each card played from exile, becoming a huge threat in Prosper's deck.; card_name: Wild-Magic Sorcerer, why_undervalued: A 2/3 that lets you play the top card of your library when you cast an instant or sorcery, effectively giving you an extra exile-to-cast trigger.; card_name: Professional Face-Breaker, why_undervalued: A 2/3 that creates a Treasure when it deals combat damage to a player, and can also rummage, providing card filtering.; card_name: Grim Hireling, why_undervalued: A 3/2 that creates Treasures when your creatures deal combat damage, and can sacrifice Treasures to remove creatures, providing both ramp and removal.

Pipeline stages

Deterministic code does the assembly. Counts and timings below are what this run recorded.

  1. Hard filters

    Color identity, Commander legality, singleton and per-card price ceiling leave 12,524 candidate cards. (1.1 s)

  2. Role scoring and Pareto pruning

    Each candidate is scored on synergy, mana efficiency and replacement value. Candidates dominated on every objective are dropped, leaving 1,102. 0 protected strategy and infrastructure cards are reserved before pruning so they cannot be lost. (3.3 s)

  3. Strategy plan

    Archetype general, status unavailable. Requirements: none. Final counts: none.

    No specialized archetype plan; existing protected-engine contract remains active.

  4. Role targets

    Targets come from the commander template, which bounds what the optimizer aims for.

    RoleTargetFinalStatus
    Ramp1111met
    Card draw68met
    Removal69met
    Board wipes23met
    Win conditions88met
    Tutors62short
    Protection85short
    Recursion53short
  5. Infrastructure and synergy fill

    Infrastructure placed first: Sol Ring, Arcane Signet, Abrade, Infernal Grasp, Feed the Swarm, Vandalblast, Swiftfoot Boots, Lightning Greaves. A greedy fill then adds the card with the best marginal objective until 99 slots are filled (synergy matrix over 1,102 candidates).

  6. Swap refinement

    The optimizer proposed 23 one-for-one swaps, each improving its current objective. Under the production preserve policy, a change set must pass a function-preservation check. This one was rejected (supported_function_loss, unknown_removed_functionality, missing_one_to_one_substitution_proof, deck_support_loss_or_unmodeled_dependency), so the previous list was kept.

  7. Budget repair and rebalance

    The optimizer proposed 0 upgrade(s), 2 unbundle(s) and 0 downgrade(s), for a mainboard total of $149.97. Under the production preserve policy, a change set must pass a function-preservation check. This one was rejected (supported_function_loss, unknown_removed_functionality, missing_one_to_one_substitution_proof, deck_support_loss_or_unmodeled_dependency), so the previous list was kept.

    Mainboard total after this stage: $145.93 (97.3% of budget).
