Overview:

This Prosper, Tome-Bound deck leverages exile-casting synergies and Treasure token generation to fuel value engines and win through artifact/drain synergies. Prosper acts as the linchpin, enabling consistent exiled card access and Treasure generation. Secondary "hidden commander" roles emerge with key pieces like Xorn (Treasure multiplier) and Marionette Master (Treasure payoff). The deck aims to win via incremental drain effects, Revel in Riches alt-win, or combat damage amplified by Treasure-powered threats.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Deploy Prosper and Treasure generators (Grim Hireling, Professional Face-Breaker). Use exile-cast enablers like Laelia and Wild-Magic Sorcerer to generate value.
2. Midgame Engine (Turns 5-7): Activate drain engines (Marionette Master, Zulaport Cutthroat) while stockpiling Treasures. Use Brass's Bounty or Treasure Vault for explosive mana.
3. Win Conditions:
   • Treasure Overload: Win via Revel in Riches (10 Treasures) or drain opponents with Marionette Master/Xorn interactions.
   • Combat Overkill: Deploy Hellkite Tyrant/Angrath's Marauders enhanced by The Reaver Cleaver Treasures.
   • Exile Synergy: Cascade into big spells via Wild-Magic Sorcerer or cast opponents' wincons with Etali, Primal Storm.

Mulligan Priorities:

• Keep hands with Prosper + 1-2 ramp pieces (Rakdos Signet, Sol Ring).
• Prioritize early Treasure generators (Deadly Dispute, Rapacious Dragon).
• Avoid hands without exile-cast enablers or Treasure synergy cards.

Key Tips:

• Sacrifice Treasures during opponents' turns to trigger Professional Face-Breaker card advantage.
• Use Feign Death on Prosper to preserve his engine through removal.
• Hellish Rebuke punishes board wipe attempts when paired with Treasure-fueled creature deployment.

Weaknesses:

Critical

• Artifact Wipe Vulnerability: Vandalblast or Bane of Progress destroys Treasure tokens and key artifacts like Bontu's Monument, crippling the engine.
• Commander Reliance: Repeated Prosper removal (3+ times) severely throttles card advantage and Treasure generation.

Moderate

• Graveyard Disruption: Rest in Peace nullifies Whip of Erebos, Victimize, and Death Tyrant recursion.
• Stack Interaction Limits: Minimal counterspells leave key spells vulnerable to removal (only Rakdos Charm/Bedevil for protection).

Minor

• Life Drain Limits: Exsanguinate-style lifegain decks outpace incremental damage from Bastion of Remembrance.
• Flying Threats: Limited aerial blockers outside Hellkite Tyrant and Goldspan Dragon.

Most Important Cards:

• Prosper, Tome-Bound (Engine catalyst: exile access + Treasure generation)
• Xorn (Treasure multiplier for all token producers)
• Revel in Riches (Alt-win condition and Treasure payoff)
• Marionette Master (Primary drain engine with Treasures)
• Grim Hireling (Combat-triggered Treasure generation + removal)
• Pitiless Plunderer (Sacrifice synergy for Treasure recursion)
• Goldspan Dragon (Treasure acceleration and evasion threat)
• Wild-Magic Sorcerer (Free spell enabler from exile)
• Professional Face-Breaker (Card advantage engine)
• Hellkite Tyrant (Artifact theft/alt-win threat)

Attribute Ratings:

Speed: 6/10

• Can threaten Revel in Riches wins by T7-8 with optimal Treasure generation, but lacks T5-6 combos seen in higher tiers.

Resilience: 5/10

• Moderate recursion (Victimize, Whip of Erebos) but over-reliant on fragile artifacts and commander.

Consistency: 7/10

• Prosper's impulse draw and multiple Treasure generators provide reliable engine starts, though tutors are limited to Diabolic Tutor.

Interaction: 5/10

• Targeted removal (Terminate, Bedevil) handles threats, but lacks stack interaction beyond situational Rakdos Charm.

Rating Justification:

This deck operates as a focused midrange build with clear win conditions and strong Treasure synergies, but its T7-8 goldfish speed and artifact dependency limit it to optimized casual tiers. Resilience against disruption is average, keeping it below high-power thresholds.

Power level: 5.5 - 6.0
