Overview:

A mono-blue spell copy deck helmed by Errant, Street Artist that focuses on generating value through copying spells and creating spell-based value engines. The deck aims to win through accumulated card advantage and eventual spell-based combos.

Primer:

The deck operates by leveraging its commander and numerous spell copying effects to multiply the value of its spells. The early game focuses on establishing mana acceleration through artifacts like Sol Ring and Sky Diamond, while setting up card selection through cantrips like Ponder and Preordain. The mid-game involves deploying value engines like Archmage Emeritus and Jin-Gitaxias, Progress Tyrant to generate card advantage while copying spells.

The deck's primary gameplan involves creating loops of copied spells to generate massive advantage, often through cost reduction effects like Baral, Chief of Compliance and Sapphire Medallion. The deck can win through various means, including creating infinite mana with High Tide loops, generating massive card advantage, or copying powerful spells like Mnemonic Deluge for overwhelming value. The commander serves as a reliable way to double spell effects at instant speed.

Weaknesses:

• Highly dependent on resolved permanents for its copying strategy
• Vulnerable to graveyard hate, which limits recursion options
• Limited creature removal options make it weak to aggressive strategies
• Struggles against permanent-based hate pieces like Null Rod or Rule of Law

Most Important Cards:

1. Jin-Gitaxias, Progress Tyrant
2. Baral, Chief of Compliance
3. High Tide
4. Archmage Emeritus
5. Swarm Intelligence
6. Dramatic Reversal
7. Sapphire Medallion
8. Mystic Sanctuary
9. Lithoform Engine
10. Complete the Circuit

Attribute Ratings:

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

Rating Justification:

This deck operates at a focused competitive level, typically threatening to establish control or win around turns 6-7. While it includes powerful spell-copying effects and interaction, it lacks the explosive fast mana and consistent early-game threats of higher-powered decks. The deck's reliance on resolved permanents and vulnerability to disruption keeps it from reaching higher power levels, but its consistent card selection and interaction suite elevates it above casual builds.

Final power level rating: 7.0 - 7.5

The deck demonstrates characteristics of a focused competitive build, with strong interaction and the ability to generate significant advantage, but lacks the consistency and speed of true cEDH decks. Its ability to copy spells and generate value while maintaining interaction puts it solidly in the focused competitive range, but its vulnerabilities and somewhat slower setup prevent it from reaching higher power levels.
