Overview:

This is a control-oriented exile/graveyard hate deck built around Ketramose, the New Dawn, utilizing mass exile effects and board wipes to control the game while drawing cards through the commander's ability. The deck employs powerful mana acceleration and efficient removal to establish control early.

Primer:

The ideal opening hand should contain fast mana (Sol Ring, Mana Vault, Chrome Mox) and early interaction (Swords to Plowshares, Path to Exile). Priority should be given to establishing mana acceleration and control pieces. The deck wants to establish its commander with protection (like Lightning Greaves) after ensuring it can be active through exile effects.

In the mid-game, focus on controlling the board through mass removal and exile effects while generating card advantage through the commander. Key decision points involve choosing when to deploy board wipes and when to hold interaction. Late game involves leveraging powerful planeswalkers like Kaya the Inexorable and alternate win conditions like Approach of the Second Sun. The deck can grind out victories through consistent exile effects and card advantage.

Weaknesses:

• Heavy reliance on the commander for card advantage makes the deck vulnerable to repeated commander removal
• Relatively low creature count makes it susceptible to aggressive strategies
• Can struggle against decks with heavy counterspell packages
• Vulnerable to artifact removal due to reliance on fast mana

Most Important Cards:

1. Sol Ring
2. Mana Vault
3. Smothering Tithe
4. Teferi's Protection
5. Opposition Agent
6. Dauthi Voidwalker
7. Rest in Peace
8. Farewell
9. The One Ring
10. Demonic Tutor

Attribute Ratings:

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

Rating Justification:

This deck sits firmly in the 8.0-8.5 range due to its fast mana package, efficient interaction suite, and ability to establish strong control by turn 3-4. While not quite reaching top-tier cEDH levels, it can consistently threaten wins through control and exile-based value engines. The presence of multiple tutors, fast mana, and efficient interaction pieces puts it above focused competitive decks but below top-tier cEDH builds.

Final power level rating: 8.0 - 8.5

The deck's high power level is supported by its robust mana base, efficient interaction package, and ability to consistently establish control early in the game while maintaining card advantage through its commander. The presence of multiple high-powered cards and synergistic effects allows it to compete at high-powered tables while falling short of the most competitive cEDH builds.
