Overview:

This Esper (WUB) deck leverages Tivit, Seller of Secrets as a potent value engine and combo facilitator. The primary strategy revolves around generating abundant artifact tokens (Treasures/Clues) through Tivit's dilemma triggers, enabling explosive turns and infinite loops with Time Sieve. Secondary win conditions include the Thassa's Oracle + Demonic Consultation/Tainted Pact combo and value-based victories through overwhelming card advantage. Tivit is essential, providing both artifact generation and a formidable flying threat, with the deck featuring robust protection and fast mana to deploy/recast it efficiently despite its 6 CMC. A "hidden commander" dynamic exists with Time Sieve, heavily tutored to enable the primary win condition.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy fast mana (Mox Diamond, Lion's Eye Diamond, Mana Vault) and stax pieces (Drannith Magistrate, Archon of Emeria) to disrupt opponents while establishing card advantage engines (Rhystic Study, Mystic Remora).
2. Commander Deployment (Turns 3-4): Cast Tivit using artifact acceleration. Leverage its dilemma trigger to create 3+ artifacts (Treasures/Clues) by voting twice. Prioritize protection (Teferi, Time Raveler, counterspells) if facing interaction.
3. Combo Execution (Turns 4-6):
   • Infinite Turns: With Tivit and Time Sieve, sacrifice 5 artifacts (easily generated from Tivit triggers) to take extra turns. Repeat via combat damage or blink effects (Displacer Kitten).
   • Thoracle Combo: Tutor for Demonic Consultation/Tainted Pact + Thassa's Oracle, exiling the library for an instant win.
4. Alternative Wins: Overwhelm with value from Consecrated Sphinx or Smothering Tithe, or control the board via stax locks and removal.

Mulligan Priorities:

• Keep hands with 2+ lands (including color fixing), fast mana, and either Tivit enablers (ramp/protection) or a tutor.
• Prioritize hands containing Time Sieve, a Thoracle combo piece, or a stax piece if going second.
• Avoid slow hands without acceleration or interaction.

Key Tips:

• Vote Manipulation: Always vote twice with Tivit, splitting choices to guarantee 3+ artifacts per trigger (1 Evidence + 1 Bribery + 1 extra vote).
• Artifact Management: Use Clues for card draw and Treasures for mana; sacrifice excess to Time Sieve or Phyrexian Tower.
• Protection Sequencing: Cast Grand Abolisher before comboing, and use free counterspells (Force of Will, Fierce Guardianship) defensively.
• Blink Synergy: Displacer Kitten resets Tivit's ETB for more artifacts and dodges removal.

Weaknesses:

Critical

• Artifact/Combo Hate: Stony Silence or Null Rod cripples mana rocks, Time Sieve, and clue sac outlets.
• Graveyard Exile: Rest in Peace disrupts Thoracle lines and recursion (Reanimate).
• Noncreature Lockouts: Deafening Silence/Rule of Law blocks multiple spells per turn, hindering combo assembly.

Moderate

• Board Wipes: Mass removal (especially exile like Farewell) resets Tivit and stax creatures, though counterspells mitigate this.
• Tax Effects: Thalia, Guardian of Thraben slows early ramp and tutor sequencing.
• Hand Disruption: Targeted discard can remove key combo pieces preemptively.

Minor

• Land Destruction: Nonbasic land hate (Blood Moon) mildly inconveniences the optimized mana base.
• Commander Tax: Repeated Tivit removal strains resources despite ramp, delaying the engine.

Most Important Cards:

• Time Sieve (Primary win condition with Tivit for infinite turns)
• Tivit, Seller of Secrets (Core value engine and combo facilitator)
• Demonic Consultation (Thoracle combo piece)
• Thassa's Oracle (Alternate win condition)
• Demonic Tutor (Tutors any combo piece)
• Lion's Eye Diamond (Explosive mana for early Tivit/combos)
• Teferi, Time Raveler (Protects combos, enables instant-speed sorceries)
• Force of Will (Free interaction to protect wins)
• Vampiric Tutor (Sets up critical top-decks)
• Smothering Tithe (Accelerates artifacts for Time Sieve)

Attribute Ratings:

Speed: 9/10

• Consistently threatens T3-4 wins with ideal hands (e.g., fast mana into Tivit + Time Sieve) and goldfishes wins by T4-5 through combos or infinite turns.

Resilience: 8/10

• Extensive protection (free counterspells, Grand Abolisher) and redundancy (10+ tutors) mitigate disruption, though reliant on noncreature permanents vulnerable to specific hate.

Consistency: 9/10

• High tutor density and card draw engines reliably access combo pieces; Tivit's artifact generation ensures fuel for multiple win paths.

Interaction: 9/10

• Premium counterspells (Force of Negation, Mana Drain), targeted removal (Swords to Plowshares, Void Rend), and stax pieces provide comprehensive disruption at minimal tempo cost.

Rating Justification:

This deck operates at cEDH tier 1 levels, capable of T3-4 wins with robust protection and near-unbreakable locks via infinite turns or Thoracle. Its speed and consistency align with tier 1 cEDH, though slight vulnerability to specific hate prevents a perfect 10.

Power level: 9.0 - 9.5
