Overview:

This is a highly tuned Ketramose, the New Dawn deck focused on leveraging exile effects and life payment to establish fast card advantage while assembling game-ending combos. The deck utilizes efficient tutors, fast mana, and protection pieces to execute its strategy consistently in the early turns.

Primer:

The deck aims to establish early advantage through fast mana (Sol Ring, Mana Vault, Chrome Mox, etc.) while setting up card advantage through Necropotence or Ad Nauseam. The commander serves as both a card advantage engine and potential combat threat, though it's not critical to the deck's primary win conditions.

Ideal opening hands should contain 2-3 lands (including at least one black source), 1-2 pieces of fast mana, and either a tutor or card advantage piece. Key early game decisions revolve around whether to establish Necropotence or hold interaction. The deck can win through various lines including Ad Nauseam + Angel's Grace combinations, or establishing a lock with Opposition Agent + Maralen of the Mornsong. Silence effects and Grand Abolisher protect your winning turn.

Weaknesses:

• Vulnerable to graveyard hate and Rest in Peace effects
• Relies heavily on life total as a resource, making it susceptible to aggressive strategies
• Can struggle against permanent-based hate pieces like Rule of Law
• Limited creature-based defense makes it vulnerable to combat-focused decks

Most Important Cards:

1. Ad Nauseam
2. Necropotence
3. Angel's Grace
4. Dark Ritual
5. Chrome Mox
6. Mana Vault
7. Opposition Agent
8. Silence
9. Grand Abolisher
10. Demonic Tutor

Attribute Ratings:

• Speed: 9/10
• Resilience: 7/10
• Consistency: 9/10
• Interaction: 8/10

Rating Justification:

This deck consistently threatens wins or establishes strong control by turn 3-4, with the ability to win earlier with perfect draws. The presence of multiple tutors, fast mana, and protection pieces puts it firmly in the cEDH-viable category. While not quite at the highest tier of cEDH decks, it has the tools to compete at high-powered tables and can reliably execute its strategy through disruption.

Final power level rating: 8.5 - 9.0

The deck demonstrates all the hallmarks of a competitive EDH deck: efficient tutors, fast mana, compact win conditions, and strong protection pieces. While it may not consistently threaten turn 1-2 wins like the absolute highest-powered decks, it can certainly establish game-ending positions by turn 3-4 with reasonable consistency.
