Overview:

This mono-green Vorinclex, Monstrous Raider deck focuses on proliferating poison counters through infect/toxic creatures and doubling their impact via Vorinclex's counter manipulation. The deck combines aggressive poison strategies with massive creature threats like Blightsteel Colossus and Craterhoof Behemoth, supported by proliferate engines and ramp. Vorinclex is critical to amplifying poison output and enabling explosive +1/+1 counter synergies, but the deck includes alternate win conditions via combat overruns.

Primer:

Core Strategy Execution:

1. Early Poison Setup (Turns 1-4): Deploy low-cost infect creatures (Glistener Elf, Blight Mamba) or toxic threats (Bloated Contaminator). Use ramp (Llanowar Elves, Cultivate) to accelerate Vorinclex or key proliferate engines like Evolution Sage.
2. Mid-Game Amplification (Turns 4-6): Cast Vorinclex to double poison counters and suppress opponents’ counter strategies. Use proliferate triggers (Contagion Clasp, Pollenbright Druid) to escalate poison. Deploy haymakers like Blightsteel Colossus or Phyrexian Swarmlord for immediate pressure.
3. Win Condition Execution:
   • Poison: Close games with Triumph of the Hordes, Infectious Bite, or repeated proliferate triggers.
   • Combat Overrun: Use Craterhoof Behemoth, Unnatural Growth, or Zopandrel, Hunger Dominus to buff wide boards.
   • One-Shot Kills: Blightsteel Colossus or Vorinclex-powered Inkmoth Nexus activations.

Mulligan Priorities:

• Keep hands with 2-3 lands and early ramp (e.g., Sol Ring, Llanowar Elves).
• Prioritize infect/toxic creatures or a Vorinclex + protection (Swiftfoot Boots) opener.
• Avoid hands lacking ramp or proactive plays.

Key Tips:

• Use Rogue's Passage to ensure infect/toxic creatures connect.
• Sacrifice creatures to Plaguemaw Beast for instant-speed proliferate.
• Finale of Devastation can tutor Craterhoof for a surprise win.
• Protect Vorinclex with Heroic Intervention and hexproof equipment.

Weaknesses:

Critical

• Relies heavily on Vorinclex staying in play to maximize poison efficiency.
• Limited answers to flying/reach blockers for small infect creatures.

Moderate

• Vulnerable to board wipes resetting creature-based poison engines.
• Struggles against decks with heavy creature removal or Melira, Sylvok Outcast.

Minor

• High mana costs for key threats (e.g., Blightsteel, Craterhoof) risk being stranded.
• Proliferate effects are slow without Vorinclex.

Most Important Cards:

• Vorinclex, Monstrous Raider (Poison/Counters Doubler)
• Triumph of the Hordes (Primary Poison Finisher)
• Blightsteel Colossus (One-Shot Kill)
• Craterhoof Behemoth (Combat Overrun)
• Evolution Sage (Proliferate Engine)
• Finale of Devastation (Tutor + Win Condition)
• Inkmoth Nexus (Evasive Poison Threat)
• Force of Vigor (Artifact/Enchantment Removal)
• Grafted Exoskeleton (Infect Enabler)
• Zopandrel, Hunger Dominus (Power Doubler)

Attribute Ratings:

Speed: 6/10
Can threaten poison kills by turns 5-7 with Vorinclex/proliferate, but lacks fast mana for consistent early Blightsteel/Craterhoof.

Resilience: 5/10
Moderate protection (hexproof, regeneration) but struggles to recover from Vorinclex removal or board wipes.

Consistency: 6/10
Tutors (Worldly Tutor, Sylvan Tutor) and card draw (Contaminant Grafter) provide reliable access to key pieces.

Interaction: 4/10
Limited to targeted removal (Beast Within, Force of Vigor) and combat tricks; minimal stack interaction.

Rating Justification:

This deck operates in the T7-8 win range with focused poison/combat strategies but lacks the speed and redundancy of higher-tier decks. Resilience issues against removal-heavy metas cap its power level.

Power level: 5.0 - 5.5
