Overview:

This Mardu (RWB) deck helmed by Neriv, Heart of the Storm focuses on explosive token generation and damage amplification. The strategy revolves around deploying creatures with attack triggers, creating swarms of tokens (often via "Mobilize" or "Myriad" mechanics), and leveraging Neriv's damage-doubling ability for lethal bursts. Secondary win conditions include incremental damage through Impact Tremors/Witty Roastmaster, life-drain combos with Exquisite Blood/Bloodletter of Aclazotz, and big swings with finishers like Chandra's Ignition or Crackle with Power. Neriv acts as a critical damage multiplier, enabling aggressive lines while synergizing with the deck’s token-centric combat triggers.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4):
   • Ramp with Sol Ring, Arcane Signet, or Land Tax.
   • Deploy token generators like Ainok Strike Leader or Zurgo, Thunder's Decree.
   • Cast Neriv as early as Turn 4 to enable damage doubling.

2. Midgame Pressure (Turns 5-7):

   • Overwhelm with token armies via Voice of Victory, Goldlust Triad, or Mardu Siegebreaker.
   • Amplify damage using Torbran, Thane of Red Fell or Bloodletter of Aclazotz.
   • Use Delina, Wild Mage to copy key creatures like Terror of the Peaks for repeated triggers.

3. Win Conditions:

   • Combat Swarm: Double token damage with Neriv and finish with Craterhoof Behemoth-like effects (e.g., Marshal of the Lost).
   • Burn Triggers: Impact Tremors + token spam, amplified by Neriv and Torbran.
   • Combo: Exquisite Blood + Bloodletter of Aclazotz for life-drain loops (opponent loss = your gain, doubled).
   • Burst Spells: Crackle with Power or Chandra's Ignition on a large creature.

Mulligan Priorities:

• Keep hands with 2-3 lands (including color fixing).
• Prioritize early ramp (Arcane Signet, Ruby Medallion) or a Turn 2-3 token generator.
• Ensure access to red/white/black mana for Neriv.
• Avoid hands without early plays or excessive high-cost cards.

Key Tips:

• Use Fervor/Gimli's Reckless Might to give tokens haste for immediate Neriv value.
• Protect Neriv with Lightning Greaves or Flawless Maneuver.
• Scheming Symmetry can fetch combo pieces like Exquisite Blood.
• Nahiri's Resolve resets ETB triggers and protects key creatures from removal.

Weaknesses:

Critical

• Commander Reliance: Neriv’s removal cripples damage output, and recasting for 6+ mana stalls momentum.
• Board Wipes: Blasphemous Act or Damnation resets token armies with minimal recovery tools.
• Anti-Token Tech: Cursed Totem/Torpor Orb nullifies key triggers and token synergies.

Moderate

• Combo Fragility: Exquisite Blood combos lack redundancy and are easily disrupted.
• Mana Base: Slow enters-tapped lands (e.g., Nomad Outpost) delay critical early plays.

Minor

• Limited Card Draw: Relies on Phyrexian Arena and attack triggers, risking empty hands.
• Flyer Evasion: Struggles against decks with aerial blockers if tokens lack evasion.

Most Important Cards:

• Neriv, Heart of the Storm (Damage doubling engine)
• Exquisite Blood (Life-drain combo piece)
• Impact Tremors (Incremental burn payoff)
• Torbran, Thane of Red Fell (Damage amplifier)
• Terror of the Peaks (Burn trigger enabler)
• Delina, Wild Mage (Token copier for combo lines)
• Ruinous Ultimatum (Board reset)
• Smothering Tithe (Mana acceleration)
• Vampiric Tutor (Key card fetcher)
• Witty Roastmaster (Passive damage)

Attribute Ratings:

Speed: 6/10

• Threatens wins via combat or combo by Turns 6-8, but lacks fast mana for explosive starts.

Resilience: 5/10

• Some protection (Deflecting Swat, Flawless Maneuver) but struggles to rebuild after wipes.

Consistency: 7/10

• Tutors (Vampiric Tutor, Gamble) and token redundancy ensure core plays, but combo pieces are fragile.

Interaction: 6/10

• Efficient removal (Swords to Plowshares, Deadly Rollick) and a board wipe, but minimal stack interaction.

Rating Justification:

This deck operates at a 5.5 - 6.0 power level. It combines strong token synergies and combo potential with solid tutors, but its reliance on the commander and vulnerability to board wipes cap its ceiling. The speed aligns with T7-8 wins in optimized casual play, while resilience issues prevent higher-tier placement.

Power level: 5.5 - 6.0
