Overview:

This Endrek Sahr, Master Breeder deck is a mono-black aristocrats strategy focused on sacrificing Thrull tokens and other creatures to generate value, drain opponents, and assemble game-winning combos. The deck leverages Endrek's token generation alongside powerful sacrifice outlets, death triggers, and recursion to overwhelm opponents through attrition and combo finishes.

Primer:

Core Strategy: The deck aims to flood the board with Thrull tokens via Endrek Sahr, then sacrifice them to fuel drain effects (e.g., Zulaport Cutthroat), card draw engines (e.g., Skullclamp), and combo wins. Key phases include:

1. Token Generation: Cast high-mana-value creatures (e.g., God-Eternal Bontu) to generate Thrull swarms while managing Endrek's sacrifice trigger.
2. Sacrifice Payoffs: Convert tokens into value using Phyrexian Altar, Ashnod's Altar, and Viscera Seer, while draining opponents via Blood Artist effects.
3. Combo Execution: Assemble infinite loops with Endless Cockroaches + Pitiless Plunderer + Phyrexian Altar for unlimited death triggers/mana or use Yawgmoth, Thran Physician to draw into win conditions.

Mulligan Priorities:

• Keep hands with early ramp (Sol Ring, Arcane Signet) and a sacrifice outlet (Carrion Feeder, Viscera Seer).
• Prioritize setups enabling T4 Endrek Sahr into T5 token explosion.
• Avoid hands lacking sac outlets or payoff cards.

Key Tips:

• Use Phyrexian Plaguelord and Grave Pact to control opponents' boards while advancing your strategy.
• Time Gray Merchant of Asphodel casts after establishing high devotion through Thrull spam.
• Protect key pieces with Malakir Rebirth and recursion from Whisper, Blood Liturgist.

Avoid Traps:

• Overextending into board wipes without Bastion of Remembrance or Syr Konrad, the Grim triggers.
• Sacrificing Endrek Sahr prematurely to his own trigger; use Phyrexian Tower for controlled sacrifices.

Weaknesses:

Critical:

• Foldsto graveyard hate (Rest in Peace) and artifact removal targeting Altars
• No protection for key enchantments like Grave Pact

Moderate:

• Slow recovery if multiple combo pieces are removed
• Limited instant-speed interaction

Minor:

• Vulnerable to flying threats (mitigated by drain effects)

Most Important Cards:

• Phyrexian Altar
• Pitiless Plunderer
• Yawgmoth, Thran Physician
• Ashnod's Altar
• Grave Pact
• Zulaport Cutthroat
• Skullclamp
• Bontu's Monument
• Endless Cockroaches
• Dictate of Erebos

Attribute Ratings:

Speed: 6/10

• Can assemble T5-6 infinite combos with optimal draws (Phyrexian Altar + Endless Cockroaches + payoff)
• Average goldfish win: T7-8 through incremental drain

Resilience: 5/10

• Vulnerable to targeted removal on Altars/payoff enchantments
• Limited protection beyond recursion (Malakir Rebirth, Whisper, Blood Liturgist)
• Recovers poorly from multiple wipes

Consistency: 7/10

• 4 tutors (Demonic, Vampiric, Species Specialist, Sadistic Hypnotist)
• Redundant drain effects (6+ "Blood Artist" variants)
• Strong card draw via Skullclamp/Dark Prophecy

Interaction: 5/10

• Targeted removal (Feed the Swarm, Tragic Slip)
• Stax-like effects via Grave Pact
• Lacks counterspells/proactive disruption

Rating Justification:

This deck sits between "Optimized Casual" (5.0) and "Focused" (6.0) on the rubric. It has:

• T6-7 deterministic wins with combos
• Redundant payoff engines
• Moderate interaction/weakness to hate
  Comparable to 5.5-6.0 decks but lacks the speed/protection of true high-power builds.

Power level: 5.5 - 6.0
