Overview:

This Jeskai spellslinger deck leverages Shiko and Narset's Flurry trigger to copy impactful instant/sorcery spells or draw cards, supported by token generators, storm payoffs, and graveyard recursion. The primary win conditions are storm-based damage (Grapeshot/Haze of Rage), token swarms buffed by Akroma's Will, and Underworld Breach loops with Storm-Kiln Artist/Birgi for infinite mana/spells.

Primer:

Core Strategy:

1. Early Setup: Cast cantrips (Opt, Ponder) and deploy cost reducers (Goblin Electromancer, Stormcatch Mentor) to enable multi-spell turns. Protect Shiko/Narset with Swiftfoot Boots/Deflecting Swat.
2. Engine Activation: Trigger Flurry on second spell each turn to copy key spells (Jeska's Will, Grapeshot) or refuel with card draw. Use Young Pyromancer/Monastery Mentor to build a board.
3. Win Conversion:
   • Storm: Chain copied spells (Galvanic Iteration, Twinning Staff) into Grapeshot or Haze of Rage with 10+ storm count.
   • Infinite Mana: Underworld Breach + Storm-Kiln Artist + Wheel of Fortune loops generate infinite treasures/spells.
   • Token Overrun: Akroma's Will grants evasion/indestructible to token armies from Talrand/Kykar.

Mulligan Priorities:

• Keep hands with 3 lands, 1-2 cantrips/cost reducers, and protection (Boros Charm, Flawless Maneuver).
• Prioritize setups enabling T4 Shiko/Narset with backup interaction (Mana Drain, Dovin's Veto).

Key Tips:

• Sequence spells to maximize Flurry triggers: Cast setup spell first (Faithless Looting), then payoff (Jeska's Will) as second spell.
• Use Lier, Disciple of the Drowned to rebuy key spells post-graveyard hate.
• Against stax, tutor for Prismari Command/Otawara to remove Rule of Law effects.

Weaknesses:

Critical

• Graveyard Reliance: Fold to Rest in Peace/Leyline of the Void (disables Breach/Mizzix's Mastery).
• Commander Dependency: 3+ removals on Shiko/Narset cripples Flurry engine.

Moderate

• Slow Stax Recovery: Rule of Law/Thalia effects delay critical multi-spell turns.
• Limited Combo Redundancy: Only 1-2 copies of key combo enablers (Storm-Kiln Artist, Birgi).

Minor

• Token Board Wipes: Vanquish the Horde/Akroma's Will mitigate damage from mass removal.

Most Important Cards:

• Underworld Breach
• Storm-Kiln Artist
• Birgi, God of Storytelling
• Mizzix's Mastery
• Grapeshot
• Rhystic Study
• Archmage Emeritus
• Lier, Disciple of the Drowned
• Wheel of Fortune
• Jeska's Will

Attribute Ratings:

Speed: 6/10
Theoretical T5-6 wins with perfect Breach/Storm-Kiln loops, but typically goldfishes T7-8.

Resilience: 5/10
Moderate protection (Deflecting Swat, counterspells) but crumbles under layered disruption.

Consistency: 6/10
12+ cantrips and wheels ensure gas, but only 4 tutors (Imperial Recruiter, Mizzix's Mastery) for combo assembly.

Interaction: 7/10
S-Tier counters (Mana Drain), A-Tier removal (Swords to Plowshares), and flexible answers (Prismari Command).

Rating Justification:

This deck operates at the high end of optimized casual (T8-10 deterministic wins) with storm/combat flexibility but lacks cEDH-speed tutors and free interaction.

Power level: 5.0 - 5.5
