Overview:

This Mardu (RWB) deck leverages Olivia, Opulent Outlaw as a value engine/combo facilitator in a high-speed, disruption-heavy shell. The primary strategy revolves around generating explosive mana via rituals (Dark Ritual, Rite of Flame), fast artifacts (Mox Diamond, Lion's Eye Diamond), and Treasures to power out game-winning combos or reanimation targets like Rakdos, the Muscle. Olivia enables Treasure generation through Outlaw combat damage (synergizing with cards like Ragavan, Nimble Pilferer and Dauthi Voidwalker) and provides a mana sink for counters. However, the deck functions primarily as a turbo Ad Nauseam/Underworld Breach combo list, using Olivia's colors and incidental Outlaw synergy for consistency. Key win conditions include Breach + Lion's Eye Diamond + Wheel of Fortune loops, Yawgmoth's Will recursion, and reanimating bombs. The commander is synergistic but not essential; the deck can win without her.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 0-2): Mulligan aggressively for fast mana (e.g., Mox Diamond, Lion's Eye Diamond, Dark Ritual, Sol Ring) and tutors (Vampiric Tutor, Gamble). Deploy mana sources and disruption (Thoughtseize, Silence, Orim's Chant). Use fetches (Polluted Delta, etc.) to fix colors. Gemstone Caverns can accelerate non-starting hands.
2. Turbo Draw/Setup (Turns 2-4): Cast Ad Nauseam or Tainted Pact to dig for combo pieces/protection. Alternatively, leverage Underworld Breach with rituals/Lion's Eye Diamond to fuel graveyard recursion. Jeska's Will provides burst mana/card advantage if Olivia is out. Reanimate key threats (e.g., Rakdos, the Muscle, Grand Abolisher) early if possible.
3. Win Execution (Turns 1-4):
   • Breach Combo: Cast Underworld Breach, then use Lion's Eye Diamond + a wheel (Wheel of Fortune) to generate mana/draw your deck. Loop rituals or Yawgmoth's Will to cast Thassa's Oracle (if included) or drain via Rakdos, the Muscle/Graywater's Fixer.
   • Ad Nauseam Storm: Draw most of your deck with Ad Nauseam, then use rituals and Lion's Eye Diamond to generate mana for a storm finisher like Tendrils of Agony (implied) or reanimate a bomb.
   • Reanimation: Cheat Rakdos, the Muscle or Akul the Unrepentant via Reanimate, Animate Dead, or Dance of the Dead to pressure life totals/exile libraries.
   • Treasure Synergy: Use Olivia's ability with mass Treasures (e.g., from Smothering Tithe or Deadly Dispute) to buff creatures for lethal combat, enabled by Vihaan, Goldwaker's animation effect.

Mulligan Priorities:

• Critical: 2+ lands (including B/R source), 1+ fast mana artifact (Mox Diamond, Lion's Eye Diamond, Sol Ring), and 1 payoff/tutor (Ad Nauseam, Underworld Breach, Vampiric Tutor, Demonic Tutor).
• Strong: Fast mana + a ritual (Dark Ritual, Rite of Flame) or a reanimation spell (Reanimate, Animate Dead).
• Avoid: Hands lacking early mana acceleration, lands that enter tapped, or only high-CMC cards without setup.

Key Tips:

• Sequence Breach Carefully: Cast Underworld Breach only when you can win that turn or protect it. Use Emergence Zone for surprise Breach/Silence.
• Leverage LED: Lion's Eye Diamond enables Breach combos, fuels Culling the Weak, and discards reanimation targets. Crack it in response to draw spells/tutors.
• Protect Combos: Use free interaction (Deflecting Swat, Red Elemental Blast) and stax (Grand Abolisher, Opposition Agent) to shield your turn. Silence/Orim's Chant lock opponents out during critical phases.
• Tutor Flexibly: Fetch interaction (Swords to Plowshares, Thoughtseize) against threats, or grab combo pieces (Breach, LED, Yawgmoth's Will) when safe.
• Recurse Aggressively: Yawgmoth's Will and Underworld Breach allow replaying tutors/interaction from the graveyard for multiple win attempts.

Weaknesses:

Critical

• Graveyard hate (Rest in Peace, Leyline of the Void) cripples Breach, reanimation, and Yawgmoth's Will.
• Drannith Magistrate prevents casting from exile (disabling Breach, Ragavan, Gonti) and non-hand sources.
• Anti-artifact stax (Null Rod, Collector Ouphe) shuts down fast mana, Treasures, and LED combos.

Moderate

• Early discard/stack interaction can disrupt combo setup due to low redundancy in key pieces (e.g., only 1 Breach/LED).
• Land destruction (Blood Moon, Back to Basics) strains the greedy mana base despite fetches.
• Rule of Law effects limit spell chains, though the deck runs answers (Deadly Dispute, Swords to Plowshares).

Minor

• Board wipes can delay combat/Outlaw plans, but the deck prioritizes non-combat wins.
• Life loss from Ad Nauseam, shocks, and Ancient Tomb adds up against aggressive decks.

Most Important Cards:

• Underworld Breach (Primary combo engine)
• Lion's Eye Diamond (Combo enabler, mana burst)
• Ad Nauseam (Deck-draw engine, finds combos)
• Demonic Tutor (Finds any combo piece/answer)
• Dark Ritual (T1/T2 acceleration)
• Yawgmoth's Will (Recursion engine, secondary win)
• Vampiric Tutor (Sets up next draw)
• Mox Diamond (Fast mana, color fixing)
• Rakdos, the Muscle (Reanimation target, value engine)
• Silence (Protects combo turns)

Attribute Ratings:

Speed: 9/10

• Capable of T1-T3 wins with ideal hands (e.g., Ritual + LED + Breach + Wheel), consistently threatens wins by T3-4 via Ad Nauseam or reanimation.

Resilience: 7/10

• Runs free interaction, protection, and recursion (Breach/Will) to fight through disruption, but folds to specific, resolved hate pieces like Rest in Peace.

Consistency: 8/10

• 10+ tutors, abundant draw (Ad Nauseam, Tainted Pact, Wheel), and functional redundancy (multiple reanimation spells) ensure frequent access to combo pieces.

Interaction: 8/10

• Efficient, varied answers (Thoughtseize, Swords to Plowshares, Deflecting Swat, Red Elemental Blast, Opposition Agent) disrupt opponents at key moments, though lacks board wipes.

Rating Justification:

This deck operates at cEDH speeds (T1-T4 wins) with high consistency and robust interaction, aligning with Tier 1.5-2 cEDH decks. Its resilience is slightly below top-tier due to vulnerability to graveyard/artifact hate, preventing it from reaching Tier 0-1.

Power level: 8.5 - 9.0
