Overview:

This Brokkos, Apex of Forever deck combines infect/toxic creatures with proliferate synergies to deliver poison counter victories. The strategy leverages Brokkos' mutate recursion to create persistent threats while using Sultai's control tools to protect its fragile 1/1 infect creatures. Key strengths include redundant poison enablers, strong interaction suite, and graveyard resilience.

Primer:

Core Strategy: This deck aims to poison opponents through three primary vectors:

1. Early infect creatures (Blighted Agent, Glistener Elf)
2. Proliferate engines (Flux Channeler, Thrummingbird)
3. Mutate-enhanced threats (Brokkos + Plague Stinger). The backup plan uses Brokkos' 6/6 trample body as commander damage pressure.

Key Lines:

• T1: Land + Glistener Elf (immediate threat)
• T3: Blighted Agent + protection (Vines of Vastwood)
• Midgame: Ichor Rats + proliferate spells to spread poison
• Late Game: Skithiryx with Whispersilk Cloak as finisher

Mulligan Priorities:

1. At least 2 lands including green/black sources
2. 1-2 early infect creatures
3. 1 protection/interaction spell
4. Bonus: Proliferate engine (Thrummingbird/Evolution Sage)

Critical Interactions:

• Necrogen Communion on Brokkos creates recursive 6/6 toxic threats
• Sword of Truth and Justice adds +1/+1 counters while proliferating poison
• Inkmoth Nexus + Grafted Exoskeleton = 2-turn lethal

Optimization Tips:

• Mutate Brokkos under creatures to dodge commander tax
• Use Volrath's Stronghold to rebuy key infect creatures
• Prioritize protecting Blighted Agent over other threats

Weaknesses:

Critical:

• Vulnerable to mass artifact/enchantment removal (loses key equipment/auras)
• Weak to Solemnity/Melira, Sylvok Outcast effects

Moderate:

• Relies on 1-toughness creatures (folds to Pyroclasm effects)
• Limited poison redundancy if key creatures get exiled

Minor:

• Mana base vulnerable to Blood Moon (4 basics total)

Most Important Cards:

• Skithiryx, the Blight Dragon
• Blighted Agent
• Inkmoth Nexus
• Sword of Truth and Justice
• Grafted Exoskeleton
• Thrummingbird
• Flux Channeler
• Phyresis
• Whispersilk Cloak
• Ezuri, Stalker of Spheres

Attribute Ratings:

Speed: 6/10

• Can deliver T4-5 kills with perfect draws (Blighted Agent + 3 proliferates)
• Average goldfish win: T7-8
• Lacks fast mana outside Sol Ring

Resilience: 5/10

• 8 protection spells (Heroic Intervention, Sylvan Safekeeper)
• Graveyard recursion for creatures
• Fragile to board wipes pre-T5

Consistency: 7/10

• 6 proliferate engines + 3 tutors (Insatiable Avarice, etc.)
• Strong draw engines (Rhystic Study, Sylvan Library)
• Multiple poison vectors (infect/toxic/direct counters)

Interaction: 8/10

• 12 targeted removal/counters (S-Tier: Fierce Guardianship, A-Tier: Assassin's Trophy)
• Cyclonic Rift as board reset
• Lacks stack-based protection for combo turns

Rating Justification:

This deck sits between Rubric 5.5 (High-Power Casual) and 6.0 (Focused). It's faster than typical combat-focused decks with its poison clock, but lacks the T3-4 win consistency of true combo decks. The interaction suite matches optimized casual builds, while the fragile creature base prevents higher resilience scores. Compared to cEDH tiers, it's too slow and vulnerable to hate cards.

Power level: 5.5 - 6.0
