Overview:

This Gruul deck leverages explosive mana acceleration and versatile combo lines to threaten wins as early as turn 2. While helmed by Tovolar, Dire Overlord for incidental card draw, the deck functions primarily as a high-velocity combo engine, utilizing Underworld Breach loops, Kiki-Jiki, Mirror Breaker pairings, and Selvala, Heart of the Wilds synergies. Tovolar provides minor tribal support but isn't essential to the core strategy—win conditions rely on artifact-based mana generation and creature combos rather than werewolf synergies. The deck's speed and tutor density allow it to pivot between multiple efficient win lines under minimal disruption.

Primer:

Core Strategy Execution:

1. Explosive Start (Turns 1-2): Deploy fast mana (e.g., Mana Vault, Lotus Petal, Simian Spirit Guide) to cast setup pieces like Goblin Engineer, Selvala, Heart of the Wilds, or Survival of the Fittest. Prioritize landing Underworld Breach or Birgi, God of Storytelling for resource recursion/acceleration.
2. Combo Assembly (Turns 2-4): Use tutors (Gamble, Worldly Tutor, Imperial Recruiter) to find combo components:
   • Kiki-Jiki + Combat Celebrant: Copy Celebrant, exert for infinite combat phases.
   • Dualcaster Mage + Twinflame: Create infinite hasty tokens.
   • Breach + Lion's Eye Diamond + Wheel of Fortune: Generate storm mana, draw deck, win via Purphoros, God of the Forge or Craterhoof Behemoth.
   • Selvala + Staff of Domination: Generate infinite mana with a 5+ power creature, draw deck, win with Craterhoof.
3. Protection & Redundancy: Deploy Allosaurus Shepherd or Veil of Summer pre-combo. Use Goblin Welder to recur artifacts if disrupted.

Mulligan Priorities:

• Keep hands with ≥1 land, fast mana (e.g., Sol Ring, Mox Diamond), and a tutor/combo piece.
• Favor hands with Breach, LED, or a creature tutor. Avoid slow hands lacking acceleration.

Key Tips:

• Sacrifice Lion's Eye Diamond to Goblin Engineer to fetch Staff of Domination for Selvala loops.
• Underworld Breach can escape rituals (Pyretic Ritual, Rite of Flame) for explosive mana.
• Deflecting Swat protects combos at instant speed for free if commander is out.

Weaknesses:

Critical

• Graveyard hate (e.g., Rest in Peace) cripples Breach, recursion, and escape combos.
• Artifact lockdown (Null Rod, Stony Silence) disables mana rocks, Staff of Domination, and Welder/Engineer.
• Torpor Orb effects disrupt Dualcaster Mage, Terror of the Peaks, and Imperial Recruiter.

Moderate

• Stack interaction can disrupt combo turns despite protection spells; relies on limited counters (Pyroblast/Veil).
• Board wipes delay creature-based combos (Kiki-Jiki, Selvala) if protection isn't drawn.

Minor

• Land destruction may slow mana but is mitigated by dorks and rituals.
• Color screw is rare due to robust fixing, but nonbasic hate (Blood Moon) can strain colored sources.

Most Important Cards:

• Underworld Breach (Enables graveyard combos with LED/Wheel)
• Lion's Eye Diamond (Breach fuel, ritual effect for storm)
• Kiki-Jiki, Mirror Breaker (Primary combo engine with Combat Celebrant)
• Selvala, Heart of the Wilds (Mana generator, Staff combo piece)
• Staff of Domination (Infinite mana/draw with Selvala)
• Gamble (Tutors any combo piece at instant speed)
• Survival of the Fittest (Searches creatures, enables graveyard setups)
• Combat Celebrant (Infinite combat with Kiki-Jiki)
• Dualcaster Mage (Infinite tokens with Twinflame)
• Craterhoof Behemoth (Primary combat finisher)

Attribute Ratings:

Speed: 9/10

• Wins consistently by turn 3 with fast mana and tutors; Breach/LED or Selvala/Staff can win turn 2 unimpeded.

Resilience: 7/10

• Robust protection (Veil, Pyroblast, Deflecting Swat) and recursion (Breach, Welder), but folds to resolved graveyard/artifact hate.

Consistency: 9/10

• 12+ tutors and ample draw (Wheel, Sylvan Library) ensure reliable access to combo pieces.

Interaction: 7/10

• Efficient targeted removal (Beast Within, Force of Vigor) and stack protection, but lacks board wipes and non-creature counters.

Rating Justification:

This deck operates at cEDH viability with turn 2-3 win potential through redundant combos and exceptional tutoring, aligning with tier 8.5-9.0 speed. However, its fragility to common meta hate (graveyard/artifact lockdown) prevents consistent "near-unbreakable" execution, capping it below tier 9.5.

Power level: 8.5 - 9.0
