Overview:

A focused mill strategy leveraging Phenax, God of Deception's ability to turn creature toughness into mill potential, supplemented by additional mill effects and card draw engines to consistently deplete opponents' libraries.

Primer:

The deck operates primarily through a combination of passive and active mill strategies. The commander, Phenax, God of Deception, turns every creature into a potential mill engine, with particular emphasis on high-toughness creatures like Consuming Aberration and Fleet Swallower. The deck includes multiple layers of mill effects, from creatures like Bruvac the Grandiloquent that double mill effects, to enchantments like Fraying Sanity that create multiplicative mill potential.

The strategy is supported by a robust suite of card draw and tutors, including Rhystic Study, Teferi's Ageless Insight, and Demonic Tutor. The deck can pivot between aggressive mill strategies and controlling the game through counterspells and removal. Alternative win conditions include Thassa's Oracle, which can capitalize on emptied libraries, and combat damage through creatures that grow with graveyard size like Consuming Aberration.

Weaknesses:

• Vulnerable to graveyard shuffling effects like Eldrazi titans or Gaea's Blessing
• Limited creature removal makes it susceptible to aggressive creature strategies
• Relies heavily on enchantments, making it vulnerable to enchantment removal
• Can struggle against multiple opponents due to having to mill multiple libraries

3. Fraying Sanity
4. Mesmeric Orb
5. Rhystic Study

Attribute Ratings:

• Speed: 5/10
• Resilience: 6/10
• Consistency: 7/10
• Interaction: 6/10

Rating Justification:

This deck sits comfortably in the 6.0-6.5 range due to its focused strategy and ability to consistently execute its gameplan. While it includes powerful cards and tutors, the mill strategy inherently requires multiple turns to achieve victory, even with optimal draws. The deck's interaction suite and ability to protect its strategy through counterspells elevates it above casual builds, but it lacks the explosive speed and protection of higher-powered decks.

Final power level rating: 6.0 - 6.5

The deck demonstrates a clear focus on its mill strategy with good tutor effects and card advantage engines, but its reliance on multiple pieces to achieve victory and vulnerability to common counterplay keeps it from reaching higher power levels. The inclusion of cards like Fierce Guardianship and Cyclonic Rift shows optimization, but the overall strategy remains fair and interactive rather than explosive or oppressive.
