Overview:

Prosper, Tome-Bound leverages exile synergy and Treasure generation to fuel value engines and multiple win conditions. The deck combines artifact payoffs like Reckless Fireweaver, Marionette Master, and Revel in Riches with aggressive impulse-draw tools and Treasure doublers like Xorn. While lacking infinite combos, it uses high-impact synergies and tutor density to consistently pressure opponents through incremental damage and explosive turns.

Primer:

Core Strategy:
This deck aims to resolve Prosper early and capitalize on his exile-to-Treasure engine. Key phases:

1. Setup (Turns 1-4): Ramp with Treasures/rocks, cast Prosper, and establish value engines like Wild-Magic Sorcerer or Laelia.
2. Value Amplification (Turns 5-7): Deploy payoff creatures like Marionette Master or Terror of the Peaks, using Treasures to cast exiled cards and trigger damage effects.
3. Closing (Turns 7+): Leverage accumulated Treasures for explosive plays with Goldspan Dragon or Chandra's Ignition, or win via Revel in Riches/overwhelming pings from artifact synergies.

Key Interactions:

• Xorn + Grim Hireling creates 3 Treasures per combat hit
• Academy Manufactor turns Prosper’s Treasures into Clue/Food/Treasure triples
• Mayhem Devil punishes Treasure sacrifices while enabling removal

Mulligan Priorities:

1. Ensure 3 lands (prioritize untapped duals)
2. Include at least 1 early ramp artifact or Treasure generator
3. Seek at least 1 payoff creature or exile engine

Weaknesses:

Critical:

• Vulnerable to artifact hate (e.g., Collector Ouphe, Null Rod shuts down 40% of the deck)
• Relies on creature-based payoffs with minimal protection

Moderate:

• Limited graveyard recursion for key pieces
• Struggles against fast combo decks pre-T6

Minor:

• Some tapped lands slightly slow early turns

Most Important Cards:

• Revel in Riches
• Xorn
• Academy Manufactor
• Marionette Master
• Demonic Tutor
• Goldspan Dragon
• Grim Hireling
• Mayhem Devil
• The One Ring
• Reckless Fireweaver

Attribute Ratings:

Speed: 6/10
Can threaten wins by T7-8 through Treasure-fueled damage bursts, but lacks T4-5 combos. Early acceleration via Ancient Tomb/Sol Ring enables T3 Prosper.

Resilience: 6/10
Moderate protection (Deflecting Swat, Lightning Greaves) and redundancy in payoff creatures, but folds to repeated artifact hate.

Consistency: 8/10
10+ tutors/impulse draws (Vampiric Tutor, Jeska's Will) ensure frequent access to key pieces. Prosper’s innate card advantage provides steady value.

Interaction: 6/10
Efficient spot removal (Feed the Swarm, Rakdos Charm) and board wipes (Blasphemous Act), but lacks free counterspells for combo protection.

Rating Justification:

This deck sits between the rubric’s 6.0 ("Focused – T7-8 via synergies") and 6.5 ("Optimized – T6-7"). While its Treasure engine provides cEDH-adjacent value, the absence of infinite combos and reliance on combat-oriented wincons place it solidly in focused territory. It outpaces casual decks through tutor density and explosive mid-game turns but lacks the interaction suite and speed of true cEDH builds.

Power level: 6.0 - 6.5
