Overview:

This Narset, Jeskai Waymaster deck is a high-powered storm/combo build focused on casting numerous low-cost spells per turn to fuel explosive draws and game-ending synergies. The core strategy leverages Narset's end-step hand refill alongside free/cheap interaction, artifact-based mana acceleration, and multiple infinite mana lines to enable Thoracle/Brain Freeze wins or storm kills with Grapeshot.

Primer:

Core Strategy:
The deck operates in three phases:

1. Setup: Deploy fast mana (Mox Opal, Lion's Eye Diamond) and card selection (Brainstorm, Sensei's Divining Top). Use Displacer Kitten/Teferi, Time Raveler to protect key pieces while building storm count.
2. Acceleration: Cast Birgi, God of Storytelling or Storm-Kiln Artist to generate mana/card advantage through spellcasting. Use Isochron Scepter imprinted with Dramatic Reversal (with 3+ mana rocks) for infinite mana.
3. Finale: Convert resources into Thassa's Oracle/Brain Freeze kills or Grapeshot storm. Alternative lines include Timetwister loops with Lion's Eye Diamond and Underworld Breach-style recursion via Sevinne's Reclamation.

Key Interactions:

• Displacer Kitten + Teferi, Time Raveler: Reset planeswalkers while generating value
• Auriok Salvagers + Lion's Eye Diamond: Infinite colored mana
• Dualcaster Mage + Jeska's Will: Copy exiled cards for massive advantage

Mulligan Priorities:

1. 2-3 lands (preferably untapped)
2. Fast mana (Sol Ring, Chrome Mox)
3. Card selection (Faithless Looting, Brainstorm)
4. At least 1 protection piece (Grand Abolisher, Silence)

Critical Sequencing:

• Cast Narset only when ready to chain 3+ spells
• Time Leyline of Anticipation/Vedalken Orrery effects to play around interaction
• Prioritize resolving Rhystic Study before storm turns

Weaknesses:

Critical:

• Relies on 2-card combos vulnerable to artifact/enchantment removal
• Limited board presence makes it susceptible to early aggression

Moderate:

• Graveyard hate (Rest in Peace) disrupts recursion lines
• Drannith Magistrate/Archivist of Oghma negates key synergies

Minor:

• Blood Moon effects slightly hinder mana base
• Lacks permanent-based win conditions

Most Important Cards:

• Lion's Eye Diamond
• Thassa's Oracle
• Isochron Scepter
• Brain Freeze
• Rhystic Study
• Mystic Remora
• Teferi, Time Raveler
• Dualcaster Mage
• Displacer Kitten
• Timetwister

Attribute Ratings:

Speed: 8/10

• T3 wins possible with perfect hands (LED + Salvagers + Oracle)
• Consistent T4-5 goldfish

Resilience: 7/10

• 8 free/low-cost counterspells (Force of Negation, Fierce Guardianship)
• Multiple redundant combo lines

Consistency: 8/10

• 14 tutors/card selection engines (Enlightened Tutor, Mystical Tutor, Spellseeker)
• 3+ copies of key effects (ritual effects via Jeska's Will, Snap)

Interaction: 9/10

• S-tier counters (Force of Negation, Mental Misstep)
• Targeted removal for all permanent types (Path to Exile, Pongify)

Rating Justification:

This deck operates at cEDH-adjacent levels with:

• Multiple T3 deterministic win lines
• Robust interaction suite comparable to tier 2 cEDH decks
• Better mana base than most optimized casual decks
• Lacks the redundancy/protection density of true tier 1 cEDH

While slightly below cEDH's extreme optimization (no Ad Nauseam, limited Underworld Breach lines), it far exceeds typical high-power casual decks in speed and consistency. Matches rubric 7.5-8.0 through:

• T4-5 effective wins via stax-proof combos
• 8/10 interaction score matching "Highly Optimized" tier
• Tutor density enabling consistent T5-6 wins through disruption

Power level: 7.5 - 8.0
