Overview:

This Abzan deck helmed by Betor, Ancestor's Voice focuses on life manipulation synergies, using lifegain triggers to fuel +1/+1 counters, creature recursion, and opponent life drain. The commander enables incremental value by rewarding both life gain (through counter distribution) and life loss (via graveyard recursion). Primary win conditions center around stacking lifegain/drain effects like Vito, Thorn of the Dusk Rose, Sanguine Bond, and Exsanguinate, supported by a subtheme of +1/+1 counter proliferation with Corpsejack Menace and Kami of Whispered Hopes. Betor acts as a value engine but isn't strictly essential to the strategy, as the deck can win through standalone drain effects.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Deploy lifegain engines (Soul Warden, Dina, Soul Steeper, Rhox Faithmender) and ramp (Sol Ring, Arcane Signet, Nature's Lore). Prioritize fixing mana with slow dual lands.
2. Midgame Triggers (Turns 5-7): Resolve key payoff cards like Vito, Thorn of the Dusk Rose, Sanguine Bond, or Pontiff of Blight. Use Betor to recur critical creatures (e.g., Gray Merchant of Asphodel) and amplify +1/+1 counters on threats like Wall of Limbs.
3. Win Conditions (Turns 8+):
   • Drain Combos: Activate stacked lifegain triggers (e.g., Vito + Sanguine Bond doubles drain damage).
   • X-Spikes: Cast Exsanguinate or Debt to the Deathless with amplified mana from Bolas's Citadel.
   • Aetherflux Finish: Use Rhox Faithmender-enhanced lifegain to fuel Aetherflux Reservoir's 50-damage ability.

Mulligan Priorities:

• Keep hands with 3 lands (including color-fixing), at least 1 ramp artifact, and 1 lifegain engine (e.g., Soul Warden, Dina).
• Prioritize early plays that trigger Betor’s end-step abilities.
• Avoid hands with only high-CMC payoffs and no ramp.

Key Tips:

• Use Bolas's Citadel with Rhox Faithmender to offset life costs and chain spells.
• Kami of Whispered Hopes amplifies Betor’s +1/+1 counters and ramps significantly with high-power creatures.
• Golgari Charm protects against board wipes or removes problematic enchantments.

Weaknesses:

Critical

• Heavily reliant on resolving and protecting 4-5 CMC enchantments (Sanguine Bond, Blind Obedience) with minimal protection.
• Limited graveyard recursion beyond Betor, making the deck fold to Rest in Peace or Leyline of the Void.

Moderate

• Slow mana base with 11+ tapped lands delays key plays by 1-2 turns.
• Minimal instant-speed interaction to disrupt opponents’ combos (only 6 targeted removal spells).

Minor

• Life payment effects (Bolas's Citadel, Greed) can backfire against aggressive decks.
• Limited card draw outside of Phyrexian Arena and Well of Lost Dreams.

Most Important Cards:

• Vito, Thorn of the Dusk Rose (Primary life-drain multiplier)
• Sanguine Bond (Doubles lifegain damage output)
• Rhox Faithmender (Lifegain amplifier for X-spells and Aetherflux)
• Bolas's Citadel (Mana cheat and win condition enabler)
• Corpsejack Menace (Doubles Betor’s +1/+1 counter output)
• Pontiff of Blight (Mass extort triggers)
• Gray Merchant of Asphodel (Devotion-based life swing)
• Aetherflux Reservoir (Alternate win condition)
• Kami of Whispered Hopes (Counter synergy and ramp)
• Kaya's Wrath (Board wipe with lifegain synergy)

Attribute Ratings:

Speed: 4/10

• Wins typically occur around T9-11 via gradual drain effects or late-game X-spells. Fast mana is limited, and the strategy requires multiple setup pieces.

Resilience: 5/10

• Moderate recursion via Betor and Revival, but key enchantments have no inherent protection. Recovery from board wipes is slow.

Consistency: 6/10

• Redundant lifegain triggers provide steady value, but only 2 tutors (Diabolic Tutor, Staff of Compleation) hinder combo assembly.

Interaction: 5/10

• Targeted removal (Swords to Plowshares, Hero's Downfall) is present but lacks counterspells or stax elements to delay opponents.

Rating Justification:

The deck’s T9-11 win potential through incremental drain and X-spells aligns with Casual/Precon tiers, while its moderate resilience and synergy lift it slightly above base precon power. The lack of fast mana and combo protection caps its ceiling.

Power level: 4.0 - 4.5
