Overview:

This Boros deck helmed by Rem Karolus, Stalwart Slayer focuses on aggressive combat strategies amplified by damage multipliers and extra combat phases. The commander enables a unique damage asymmetry: preventing incoming damage to your board while amplifying outgoing damage to opponents. The deck leverages token swarms (Soldiers, Angels), big angels, and combat tricks like City on Fire or Blade Historian to overwhelm opponents. Rem Karolus acts as a critical enabler, protecting your board from damage-based removal while turning every burn spell or combat swing into a lethal threat.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Deploy mana rocks (Sol Ring, Boros Signet), token generators (Legion Warboss, Horn of Gondor), and key protection (Grand Abolisher, Swiftfoot Boots). Use Land Tax or Sword of the Animist to fix mana.
2. Midgame Pressure (Turns 4-6): Cast Rem Karolus, then drop damage amplifiers like Gisela, Blade of Goldnight, City on Fire, or Shared Animosity. Use Aurelia, the Warleader or Karlach, Fury of Avernus for extra combats. Mondrak, Glory Dominus doubles token production for wider boards.
3. Win Conditions (Turns 6-8):
   • Combat: Swing with massive token armies buffed by Benalish Marshal, Elesh Norn, Grand Cenobite, or The Immortal Sun, amplified by Rem’s damage boost.
   • Damage Multipliers: Stack Gisela (double damage) + City on Fire (triple damage) for exponential combat or burn (e.g., Lightning Bolt becomes 8 damage to opponents).
   • Lock: Avacyn, Angel of Hope + Teferi’s Protection to make your board nearly unassailable.

Mulligan Priorities:

• Keep hands with 2-3 lands, early ramp, and at least one key piece (Rem Karolus, token generator, or damage amplifier).
• Prioritize Land Tax, Smothering Tithe, or Sword of the Animist for mana consistency.
• Avoid hands with only high-cost angels or no early plays.

Key Tips:

• Use Reconnaissance to protect attackers post-combat or untap Rem Karolus for blocking.
• Deflecting Palm becomes a 10+ damage nuke with Rem’s damage boost.
• Master Warcraft forces unfavorable blocks or prevents opponents from blocking entirely.
• Luminous Broodmoth + Resurrection Orb creates recurring threats.

Weaknesses:

Critical

• No instant-speed protection for Rem Karolus: Losing the commander neuters damage asymmetry and amplification.
• Heavy reliance on combat: Easily disrupted by fog effects, Propaganda, or mass removal like Cyclonic Rift.

Moderate

• High mana curve: Angels and multipliers like City on Fire require significant setup.
• Graveyard dependency: Celestine, the Living Saint and Sun Titan are vulnerable to Rest in Peace.

Minor

• Limited card draw: Relies on The One Ring and Esper Sentinel for sustain.
• Weak to flyers: Despite angels, lacks reach/deathtouch to block opposing flyers.

Most Important Cards:

• Gisela, Blade of Goldnight (Damage doubler, game-ending threat)
• Mondrak, Glory Dominus (Token multiplier, synergizes with Soldiers/Angels)
• Aurelia, the Warleader (Extra combats)
• Avacyn, Angel of Hope (Indestructible board lock)
• Smothering Tithe (Mana acceleration in Boros)
• City on Fire (Triples damage output)
• Teferi’s Protection (Board protection)
• Blade Historian (Double strike enabler)
• Shared Animosity (Scales with token swarms)
• Grand Abolisher (Protects combat phases)

Attribute Ratings:

Speed: 6/10
Can threaten lethal via combat or multipliers by turns 6-8, but lacks fast mana or turbo combo potential.

Resilience: 5/10
Limited recursion/protection outside key pieces like Teferi’s Protection; struggles if Rem Karolus is removed repeatedly.

Consistency: 6/10
Moderate tutor density (Enlightened Tutor, Land Tax) and card draw, but reliant on resolving critical 5-6 MV spells.

Interaction: 5/10
Spot removal (Swords to Plowshares, Chaos Warp) and board wipes (Farewell), but minimal stack interaction.

Rating Justification:

This deck has a focused combat plan with explosive damage multipliers but lacks the speed and redundancy of higher-tier decks. Its reliance on resolving 6+ MV spells and vulnerability to commander removal caps its power.

Power level: 5.0 - 5.5
