Overview:

This is a highly optimized Esper control/combo deck utilizing Tivit, Seller of Secrets as a value engine and combo piece, featuring multiple compact win conditions including Thassa's Oracle consultation lines and infinite turns through Time Sieve.

Primer:

The deck operates primarily as a control shell with a heavy emphasis on interaction and efficient mana production. The early game focuses on establishing control through stax pieces like Grand Arbiter Augustin IV and Drannith Magistrate while developing mana through fast rocks. The deck can quickly transition into its win conditions through multiple tutors and efficient card selection.

The primary win conditions involve either the Thassa's Oracle/Demonic Consultation/Tainted Pact package or generating infinite turns through Time Sieve with artifact tokens from Tivit. The deck maintains impressive consistency through a dense package of tutors, countermagic, and card selection, while protecting its gameplan with high-quality interaction. The commander provides both value through investigating/treasure generation and enables combo lines.

Weaknesses:

The deck is somewhat vulnerable to aggressive strategies that can deploy threats before control elements are established. Blood Moon effects and heavy artifact hate can disrupt the mana base and combo pieces. While the deck runs sufficient interaction, it can sometimes struggle against multiple threats from different opponents simultaneously due to the need to conserve answers for protecting its own win conditions.

Most Important Cards:

• Thassa's Oracle
• Demonic Consultation
• Time Sieve
• Mana Drain
• Force of Will
• Demonic Tutor
• Grand Arbiter Augustin IV
• Drannith Magistrate
• Displacer Kitten
• The One Ring

Attribute Ratings:

• Speed: 9/10
• Resilience: 8/10
• Consistency: 9/10
• Interaction: 10/10

Rating Justification:

This deck consistently threatens wins or establishes strong control by turn 3-4, featuring multiple compact win conditions protected by premium interaction. The density of fast mana, tutors, and interaction places it firmly in high-powered cEDH territory. While not quite at the absolute peak of optimization seen in tier 1 cEDH decks, it maintains the ability to compete at the highest levels of play and can reliably interact with or establish winning positions in the early turns.

Final power level rating: 8.5 - 9.0

The deck demonstrates all the hallmarks of a competitive EDH deck: efficient mana base, multiple compact win conditions, dense interaction suite, and the ability to consistently threaten early wins while protecting its gameplan. The commander provides both value and combo potential, though the deck isn't overly reliant on it. The presence of premium interaction and multiple paths to victory allows it to compete effectively at cEDH tables.
