Overview:

This Boros deck leverages The Jolly Balloon Man to generate explosive value through temporary creature tokens, enabling multiple infinite combos and ETB synergies. The strategy focuses on rapid assembly of game-ending loops using Kiki-Jiki/Splinter Twin combos, token-to-damage converters, and efficient tutors/protection.

Primer:

Core Strategy:
Deploy fast mana (Mana Vault, Sol Ring) to cast The Jolly Balloon Man by T2-3. Use its ability to copy creatures with ETBs (Felidar Guardian, Restoration Angel) for value or combo triggers. Transition into deterministic wins via:

1. Kiki-Jiki Combos: Pair with Felidar Guardian or Village Bell-Ringer for infinite hasty tokens.
2. Splinter Twin Lines: Enchant Dualcaster Mage or Zealous Conscripts to generate infinite attackers.
3. Sacrifice Loops: Ashnod’s Altar + token generators (e.g., commander + Anointed Procession) fuels Goblin Bombardment/Impact Tremors for lethal.

Mulligan Priorities:

• Keep hands with 2+ mana sources and a T1-T2 accelerant (Mox Opal, Jeska’s Will).
• Prioritize combo enablers (Imperial Recruiter, Goblin Engineer) or protection (Grand Abolisher).
• Reject hands lacking early interaction or ramp.

Key Tips:

• Use Underworld Breach to recur key combo pieces from the graveyard.
• Deflecting Swat and Silence protect critical turns.
• Recruiter of the Guard/Imperial Recruiter fetch Felidar Guardian or Dualcaster Mage to assemble combos.

Weaknesses:

Critical

• Glass Cannon Combos: Relies on fragile 2-card combos vulnerable to instant-speed removal.
• Graveyard Reliance: Underworld Breach and recursion folds to Rest in Peace.

Moderate

• Artifact Dependency: Mana base and key pieces (Ashnod’s Altar) are weak to Vandalblast.
• Board Wipe Recovery: Limited mass recursion outside Underworld Breach.

Minor

• Color Constraints: Struggles with enchantment removal outside Chaos Warp.

Most Important Cards:

• Felidar Guardian
• Kiki-Jiki, Mirror Breaker
• Ashnod’s Altar
• Underworld Breach
• Grand Abolisher
• Imperial Recruiter
• Recruiter of the Guard
• Dualcaster Mage
• Splinter Twin
• Goblin Bombardment

Attribute Ratings:

Speed: 8/10
Capable of T3 wins with perfect draws (e.g., T1 Mana Vault → T2 Kiki-Jiki + Felidar Guardian). Typical goldfish: T4-5.

Resilience: 6/10
Runs free interaction (Deflecting Swat, Silence) and Grand Abolisher, but combos remain disruptible.

Consistency: 7/10
12 tutors/redundant combo lines (Kiki-Jiki, Splinter Twin, Dualcaster Mage) ensure frequent assembly.

Interaction: 7/10
Efficient removal (Path to Exile, Boros Charm) and stack control (Tibalt’s Trickery), but lacks broad stax.

Rating Justification:

This deck operates at high-power casual levels with cEDH-adjacent speed but lacks the redundancy/protection density of top-tier lists.

Power level: 7.0 - 7.5
