Overview:

This Narset, Enlightened Master deck leverages her attack trigger to cheat high-impact noncreature spells for free, primarily focusing on chaining extra turns and combat phases to overwhelm opponents. The commander is the absolute core engine – enabling explosive turns by casting expensive sorceries/instants like extra turn spells without cost. Vulnerable to removal, the strategy relies heavily on protecting Narset to maintain momentum, with secondary win conditions including Thassa's Oracle/Laboratory Maniac and Approach of the Second Sun.

Primer:

Core Strategy Execution:

1. Ramp & Setup (Turns 1-4): Deploy mana rocks (Sol Ring, signets, talismans) and protection (Lightning Greaves, Swiftfoot Boots). Prioritize casting Narset by turn 4-5 using cost reducers like Emerald Medallion (not in list, but implied by curve).
2. Initial Attack (Turn 5-6): Swing with Narset to exile 4 cards. Cast free spells—ideally extra turns (Time Warp, Nexus of Fate) or extra combats (Aggravated Assault, Combat Celebrant). Use Scroll Rack/Sensei's Divining Top to manipulate topdeck.
3. Chain Turns/Combats: Use free extra turns to attack repeatedly with Narset, snowballing into more free spells. Untap effects (Sword of Feast and Famine) enable further mana generation.
4. Win Condition:
   • Combat: Multiple combat phases with pumped Narset or equipped creatures (Sword of War and Peace).
   • Combo: Cast Enter the Infinite for free, then win with Thassa's Oracle.
   • Alternate: Cast Approach of the Second Sun twice via extra turns.

Mulligan Priorities:

• Keep hands with 2-3 lands, at least one ramp artifact (e.g., Sol Ring, Arcane Signet), and protection (Lightning Greaves).
• Prioritize hands enabling T4 Narset. Avoid hands without ramp or with only high-CMC spells.

Key Tips:

• Protect Narset: Equip hexproof/shroud immediately. Gift of Immortality provides recursion against removal.
• Sequence Triggers: Use Strionic Resonator to double Narset’s exile trigger. Cast instant-speed extra combats (Fury of the Horde) after declaring attackers.
• Recovery: Cyclonic Rift resets opponents’ boards during extra turns. Long-Term Plans sets up key cards for Narset triggers.

Weaknesses:

Critical

• Commander Reliance: Repeated removal (especially board wipes) cripples the deck due to high recast costs and lack of alternative engines.
• Stack Interaction: Counterspells disrupting Narset’s trigger or key free spells (e.g., Enter the Infinite) instantly halt the game plan.
• Anti-Combat Stax: Propaganda/Ghostly Prison effects severely limit Narset attacks without tax payment.

Moderate

• Graveyard Hate: Disrupts recursion like Walk the Aeons buyback and Temporal Trespass delve.
• Rule of Law Effects: Prevent casting multiple free spells per turn, breaking combo chains.

Minor

• Hand Disruption: Limited discard protection; key cards in hand (e.g., Approach of the Second Sun) can be lost.
• Artifact Removal: Targets mana rocks, slowing Narset deployment.

Most Important Cards:

• Omniscience (Win enabler: Cast entire hand for free after Narset)
• Enter the Infinite (Primary combo: Draws library for Thassa's Oracle/Lab Man win)
• Thassa's Oracle (Main win condition)
• Aggravated Assault (Repeatable extra combats for multiple Narset triggers)
• Combat Celebrant (Creature-based extra combat enabler)
• Lightning Greaves (Essential protection for Narset)
• Scroll Rack (Sets topdeck for Narset triggers)
• Rhystic Study (Critical card draw to find pieces)
• Mystical Tutor (Fetches key extra turns/combo pieces)
• Cyclonic Rift (Board reset during extra turns)

Attribute Ratings:

Speed: 8/10

• Capable of T4-5 wins with ideal draws (ramp → protected Narset → extra turn chain into Oracle/Combat), but typically threatens wins by T5-7.

Resilience: 5/10

• Heavy protection for Narset (hexproof, recursion) and some interaction, but folds to repeated removal or counterspells targeting key triggers. Recovers poorly from board wipes.

Consistency: 7/10

• Multiple tutors (Enlightened Tutor, Mystical Tutor) and topdeck manipulation enhance access to combo pieces, but Narset’s random exile can whiff.

Interaction: 6/10

• Efficient spot removal (Swords to Plowshares, Path to Exile) and bounce (Cyclonic Rift), but lacks stack interaction beyond Narset's Reversal. Stax pieces (Blind Obedience) slow opponents.

Rating Justification:

This deck achieves T5-7 wins through explosive Narset chains and multiple efficient win conditions (Oracle, Approach, combat), aligning with the "T5-6 win/lock" benchmark (7.0). However, its vulnerability to commander removal and stack interaction prevents higher resilience, capping it at the lower end of competitive viability.

Power level: 7.0 - 7.5
