Overview:

This Boros deck helmed by Rem Karolus, Stalwart Slayer focuses on aggressive combat strategies amplified by damage multipliers and token swarms. The commander enables a unique damage-control axis, preventing self-harm from symmetrical effects like Blasphemous Act while amplifying offensive spells. Key themes include Angel/Soldier tribal synergies, extra combat phases, and explosive token generation. Rem Karolus acts as both a protective engine and damage amplifier but isn’t strictly essential to the deck’s core strategy, which can pivot to token overruns or anthem-driven combat wins.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Prioritize ramp (Sol Ring, Boros Signet, Land Tax) and early threats like Esper Sentinel or Legion Loyalist. Deploy token generators (Horn of Gondor, Legion Warboss) to build board presence.
2. Midgame Amplification (Turns 4-6): Cast key damage amplifiers (Gisela, Blade of Goldnight, City on Fire) or anthems (Benalish Marshal, Flowering of the White Tree). Use Smothering Tithe and The Immortal Sun to accelerate into high-impact plays.
3. Win Condition Execution (Turns 6-8):
   • Combat Overload: Swing with token armies buffed by Shared Animosity or Blade Historian, leveraging extra combats via Aurelia, the Warleader/Karlach, Fury of Avernus.
   • Damage Multipliers: Pair Blasphemous Act or Inferno Titan with Rem Karolus to nuke opponents’ boards while preserving yours, then finish with direct damage (Boros Charm, Lightning Bolt tripled by City on Fire).
   • Stax-Lite Lock: Deploy Archangel of Tithes or Grand Abolisher to limit opponents’ responses while building an indestructible board with Avacyn, Angel of Hope.

Mulligan Priorities:

• Keep hands with 2-3 lands and at least one ramp piece (e.g., Sol Ring, Land Tax).
• Prioritize early token generators (Legion Warboss, Assemble the Legion) or protection (Swiftfoot Boots).
• Avoid hands with only high-CMC cards unless paired with Smothering Tithe/The Immortal Sun.

Key Tips:

• Use Reconnaissance to safely attack with tapped creatures or dodge removal.
• Mondrak, Glory Dominus doubles tokens from Assemble the Legion and Horn of Gondor for exponential growth.
• Teferi's Protection or Boros Charm can protect your board during your own Blasphemous Act.

Weaknesses:

Critical

• Slow Setup: High average CMC (4.0+) and limited fast mana make the deck vulnerable to aggressive strategies.
• Exile-Based Removal: Farewell, Descend upon the Sinful, or Path to Exile bypass indestructible protections.
• Anti-Token Tech: Cursed Totem or Torpor Orb cripple token generation and ETB synergies.

Moderate

• Mana Dependency: Relies heavily on artifacts for ramp (Sol Ring, Boros Signet), which are soft to Vandalblast effects.
• Draw Consistency: Limited card advantage outside The One Ring and Esper Sentinel.

Minor

• Life Total Pressure: Lifegain synergies (Righteous Valkyrie) are sparse, making burn strategies problematic.

Most Important Cards:

• Avacyn, Angel of Hope (Indestructible board enabler)
• Mondrak, Glory Dominus (Token doubling)
• Gisela, Blade of Goldnight (Damage multiplier)
• Smothering Tithe (Ramp/treasure synergy)
• City on Fire (Triple damage finisher)
• Blasphemous Act (Board wipe + win condition)
• Aurelia, the Warleader (Extra combats)
• Teferi's Protection (Board protection)
• Elesh Norn, Grand Cenobite (Anthem + disruption)
• The Immortal Sun (Cost reduction + card advantage)

Attribute Ratings:

Speed: 5/10

• Can threaten wins via combat or amplified damage spells by turns 7-9, but high curve and setup time limit explosiveness.

Resilience: 6/10

• Multiple protection spells (Teferi's Protection, Boros Charm) and recursion (Sun Titan), but key pieces like Mondrak/Avacyn are prime removal targets.

Consistency: 5/10

• Limited tutors (Enlightened Tutor) and situational card draw make assembling combos or key multipliers inconsistent.

Interaction: 6/10

• Strong spot removal (Swords to Plowshares, Chaos Warp) and board wipes, but lacks stack interaction beyond Grand Abolisher.

Rating Justification:

This deck operates as a midrange combat/control hybrid with potent finishers but struggles with speed and consistency. Its ability to lock down games with Avacyn or Archangel of Tithes and threaten explosive turns with damage multipliers aligns it with Focused Casual tiers, though its high-CMC reliance caps its ceiling.

Power level: 4.5 - 5.0
