Overview:

This Jeskai spellslinger deck helmed by Narset, Jeskai Waymaster focuses on casting numerous low-cost spells to generate value through prowess triggers, token armies, and direct damage effects. The strategy leverages Guttersnipe, Third Path Iconoclast, and Monastery Mentor to convert spellcasting into board presence while using storm payoffs like Brain Freeze and Mizzix's Mastery as finishers. Narset serves as a critical refuel engine, enabling massive end-step card draws after explosive turns. The deck also features a secondary "hidden commander" in Kykar, Wind's Fury, which synergizes with its noncreature focus by generating mana and tokens.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy mana rocks (Sol Ring, Mox Amber), cantrips (Consider, Preordain), and value engines (Esper Sentinel, Mystic Remora). Use Ragavan, Nimble Pilferer for early pressure and treasure generation.
2. Engine Activation (Turns 4-6): Cast Narset and protect her with Grand Abolisher/Dovin's Veto. Chain spells like Frantic Search and Windfall to build storm count while generating tokens via Third Path Iconoclast. Activate Birgi, God of Storytelling or Storm-Kiln Artist for mana acceleration.
3. Win Conditions:
   • Storm Kill: Use Brain Freeze with storm count ≥10 to mill opponents, or recur it via Underworld Breach.
   • Token Overload: Pump tokens with Jeskai Ascendancy and swing with an army boosted by Monastery Mentor.
   • Infinite Mana: Kykar, Wind's Fury + Paradise Mantle + Underworld Breach enables infinite red mana for Guttersnipe pings.

Mulligan Priorities:

• Keep hands with 2-3 lands including red/blue sources.
• Prioritize early ramp (Sol Ring, Mox Amber) or card selection (Brainstorm, Ponder).
• Ensure at least one payoff creature (Guttersnipe, Storm-Kiln Artist) or protection (Grand Abolisher).

Key Tips:

• Time Narset's end-step discard strategically with Teferi's Ageless Insight or Reliquary Tower.
• Use Underworld Breach with Lotus Petal and Brain Freeze for graveyard-fueled storm turns.
• Propaganda and Evacuation buy critical time against aggressive decks.

Weaknesses:

Critical

• Foldsto Rule of Law/Eidolon of Rhetoric effects that limit spellcasting.
• Graveyard hate (Rest in Peace, Leyline of the Void) cripples Underworld Breach/Mizzix's Mastery recursion.

Moderate

• Vulnerable to board wipes clearing token armies and engine creatures.
• Struggles against fast combo decks due to limited stack interaction beyond counterspells.

Minor

• Mana base has multiple tapped lands, potentially slowing early turns.
• Cursed Totem nullifies Ragavan and Kykar's activated abilities.

Most Important Cards:

• Underworld Breach (Recursion engine for storm finishers)
• Brain Freeze (Primary storm win condition)
• Kykar, Wind's Fury (Mana generation and token synergy)
• Birgi, God of Storytelling (Mana acceleration for storm turns)
• Third Path Iconoclast (Token generation engine)
• Mizzix's Mastery (Graveyard-based spell recursion)
• Guttersnipe (Persistent damage output)
• Rhystic Study (Card advantage engine)
• Grand Abolisher (Protection during critical turns)
• Esper Sentinel (Early-game card advantage)

Attribute Ratings:

Speed: 7/10
Capable of T5-6 wins through storm or token swarm, accelerated by treasure generation and cost reducers like Stormcatch Mentor.

Resilience: 5/10
Limited protection beyond counterspells; heavily reliant on maintaining key creatures/enchantments.

Consistency: 7/10
Strong cantrip/tutor suite (12+ cantrips, Gamble, Enlightened Tutor) ensures regular access to engine pieces.

Interaction: 6/10
Efficient counterspells (Fierce Guardianship, Daze) and targeted removal, but lacks board wipes beyond Evacuation.

Rating Justification:

This deck demonstrates optimized storm potential with T5-6 win capability through redundant engines and tutors, but its vulnerability to common stax pieces and reliance on maintaining key permanents place it below cEDH viability. The balance between speed and fragility aligns with high-power casual tiers.

Power level: 6.5 - 7.0
