Overview:

A mono-blue control deck centered around Thassa, Deep-Dwelling's blink ability to generate value through ETB effects while maintaining strong control elements through counterspells and interaction.

Primer:

This deck operates as a value-oriented control strategy that uses Thassa, Deep-Dwelling's end-step blink ability to repeatedly trigger powerful enter-the-battlefield effects while maintaining control of the game through a robust suite of counterspells and interaction. The deck can win through various means, including infinite mana combos with Palinchron or Peregrine Drake, laboratory maniac effects with Thassa's Oracle, or through accumulated value and creature beats.

The deck's strength lies in its ability to play at instant speed, with numerous flash creatures and counterspells allowing it to react to opponents while developing its board state. Key value engines include repeatedly blinking creatures like Archaeomancer to recur spells, Gilded Drake to steal multiple creatures, and Spellseeker to tutor for crucial interaction pieces.

Weaknesses:

The deck can struggle against aggressive strategies that deploy multiple threats before counterspells come online. Heavy artifact/enchantment removal can disrupt the deck's mana acceleration and value pieces. The deck is somewhat reliant on its commander for its primary gameplan, though it can function without it, and can sometimes struggle to close out games quickly without its combo pieces.

Rating Justification:

This deck operates at a high-powered level with its combination of efficient interaction, strong value generation, and multiple paths to victory. It has the tools to compete with higher-powered decks through its counterspell suite and instant-speed interaction, while maintaining the ability to grind out longer games through value engines. The deck sits comfortably above casual builds due to its optimization and powerful card choices, but below the highest tier cEDH decks due to its slightly slower win conditions and reliance on creature-based strategies.

Final power level rating: 7.0 - 7.5
