Overview:

This is a Dimir (Blue-Black) deck focused on card advantage and graveyard synergies, utilizing Rona, Herald of Invasion as both a value engine and potential combo piece through her transformed side, aiming to win through either card advantage attrition or infinite loops.

Primer:

The deck operates on multiple axes, with its primary gameplan revolving around card advantage and graveyard manipulation. Rona, Herald of Invasion enables consistent card filtering and advantage, while her transformed side can potentially create infinite loops with cards like The One Ring and various cost reducers. The deck includes several ways to fill the graveyard while drawing cards, setting up for powerful plays with cards like Animate Dead and Reanimate.

The secondary strategy involves utilizing powerful draw engines like Teferi's Ageless Insight and Sheoldred, the Apocalypse to either overwhelm opponents with card advantage or drain their life totals. The deck includes a robust interaction suite with counterspells and removal, allowing it to control the game while assembling its pieces. The artifact package provides consistent ramp while enabling additional synergies with cards like Urza's Saga and various legendary artifacts.

Weaknesses:

The deck is vulnerable to graveyard hate and artifact removal, which can significantly impact its ability to execute its strategy. It relies heavily on its commander for optimal performance, making it susceptible to commander tax and removal. The relatively low creature count makes it somewhat vulnerable to aggressive strategies, though it includes several defensive options like Propaganda and removal spells.

Most Important Cards:

• The One Ring
• Sheoldred, the Apocalypse
• Teferi's Ageless Insight
• Cyclonic Rift
• Urza's Saga
• Dark Ritual
• Windfall
• Search for Azcanta
• Animate Dead
• Vilis, Broker of Blood

Attribute Ratings:

• Speed: 6/10
• Resilience: 7/10
• Consistency: 7/10
• Interaction: 8/10

Rating Justification:

The deck sits comfortably in the 6.5-7.0 range due to its ability to consistently generate advantage and interact with opponents while setting up potential game-ending combinations. While it lacks the explosive fast mana and turn 2-3 wins of higher-powered decks, it can establish strong board control by turn 5-6 and maintain it through efficient interaction and card advantage. The presence of tutors and consistent card selection puts it above casual builds, but it's not quite optimized enough to compete with true cEDH decks.

Final power level rating: 6.5 - 7.0

The deck shows clear optimization in its manabase and interaction package but intentionally avoids some of the most powerful fast mana options and infinite combos that would push it into higher power levels. It's well-positioned for high-powered casual pods but would struggle against true cEDH strategies.
