Overview:

This Bant lands-matter deck leverages Derevi's unique ability to repeatedly enter the battlefield to trigger landfall effects and untap permanents. The core strategy revolves around explosive land ramp using cards like Exploration, Burgeoning, and Oracle of Mul Daya, enabling massive value engines such as Aesi, Tyrant of Gyre Strait and Titania, Protector of Argoth. Win conditions include overwhelming combat via Avenger of Zendikar/Craterhoof Behemoth, land recursion loops with Splendid Reclamation/Scapeshift, and infinite untap combos using Staff of Domination + Seedborn Muse + Derevi. Derevi acts as both an engine enabler (untapping lands/creatures) and a combo piece, with its tax-avoiding ability providing exceptional resilience.

Primer:

Core Strategy Execution:

1. Explosive Land Setup (Turns 1-4): Prioritize land accelerators (Exploration, Burgeoning, Oracle of Mul Daya) and mana dorks (Birds of Paradise). Use tutors (Crop Rotation, Sylvan Scrying) to fetch key utility lands like Alchemist's Refuge or Mystic Sanctuary. Cast Derevi early via combat damage triggers or its ability.
2. Value Engine Activation (Turns 3-6): Deploy landfall payoffs like Aesi, Tyrant of Gyre Strait, Titania, Protector of Argoth, or Ancient Greenwarden. Leverage Derevi's triggers to untap mana sources or Seedborn Muse for explosive turns. Draw extensively via Mystic Remora, Sylvan Library, or Aesi triggers.
3. Win Condition Assembly (Turns 5-7):
   • Combat: Generate massive boards with Avenger of Zendikar + land drops or Titania tokens, then finish with Craterhoof Behemoth or Finale of Devastation (X=10+).
   • Land Recursion: Loop lands with Scapeshift/Splendid Reclamation + Ramunap Excavator/Crucible of Worlds + fetchlands, creating infinite landfall triggers/Titania tokens.
   • Infinite Untap: Assemble Seedborn Muse + Staff of Domination + Derevi. Use Muse to untap all permanents on each opponent's turn, then Staff to: 1) Untap Seedborn Muse, 2) Generate infinite mana via lands/dorks, 3) Draw deck, 4) Win via Craterhoof/Finale/Ballista.
   • Extra Turns: Recur Time Warp with Mystic Sanctuary/Eternal Witness + recursion for multiple combat phases.

Mulligan Priorities:

• Keep hands with 2-3 lands, including at least one green source.
• Prioritize hands containing early ramp (Exploration, Burgeoning, mana dork) or a land tutor (Crop Rotation, Sylvan Scrying).
• Value hands with Derevi + an evasive creature for early triggers or protection (Lightning Greaves).
• Avoid hands lacking land acceleration or clogged with high-CMC payoffs without setup.

Key Tips:

• Sequence Land Drops: Maximize landfall triggers by playing lands after deploying Dryad of the Ilysian Grove, Oracle of Mul Daya, or Ancient Greenwarden. Use Yavimaya, Cradle of Growth to enable Burgeoning off any land type.
• Abuse Derevi Triggers: Target Lotus Cobra, Carpet of Flowers, or mana dorks with Derevi's untap to generate explosive mana. Use Derevi to tap down opponents' blockers or key permanents during combat.
• Recursion Loops: Combine Intuition packages (e.g., Splendid Reclamation, Ramunap Excavator, Crucible of Worlds) for guaranteed land recursion. Recycle Time Warp with Mystic Sanctuary + shuffle effects.
• Protect Critical Engines: Shield Seedborn Muse, Titania, or Aesi with Lightning Greaves, counterspells, or Oko, Thief of Crowns's elk ability. Counter board wipes targeting your landfall payoffs.
• Flash Wins: Cast game-ending spells like Craterhoof or Scapeshift at instant speed via Alchemist's Refuge.

Weaknesses:

Critical

• Land Destruction: Mass land destruction (Armageddon, Ruination) cripples the deck's engine and win conditions. Targeted LD against utility lands (Mystic Sanctuary, Alchemist's Refuge) is also devastating.
• Graveyard Hate: Rest in Peace, Leyline of the Void shuts down land recursion (Crucible, Ramunap Excavator, Splendid Reclamation) and Eternal Witness loops.
• Anti-Search Effects: Aven Mindcensor, Opposition Agent severely disrupts the deck's heavy reliance on land and creature tutors.

Moderate

• Stack Interaction: Lacks protection against stack-based hate like Torpor Orb (stops ETB wincons) or Cursed Totem (shuts down dorks/Staff). Relies on counterspells to answer these.
• Combo Speed: Can be outpaced by faster combo decks before establishing its engine, despite interaction suite.
• Mana Base Vulnerability: Heavy reliance on non-basics makes it susceptible to Blood Moon/Back to Basics, though basics are fetchable.

Minor

• Hand Disruption: Targeted discard can remove key pieces, but the deck's high card draw mitigates this.
• Single-Target Removal: Kills Derevi/value creatures, but recursion and redundancy provide recovery paths.

Most Important Cards:

• Seedborn Muse (Enables infinite untap combo, generates massive value)
• Derevi, Empyrial Tactician (Engine, combo piece, resilient threat)
• Scapeshift (Primary land-based win enabler)
• Splendid Reclamation (Recurs lands for landfall/combat wins)
• Aesi, Tyrant of Gyre Strait (Card draw engine and landfall payoff)
• Titania, Protector of Argoth (Creates threats from land recursion)
• Exploration (Accelerates land strategy)
• Burgeoning (Explosive early land drops)
• Staff of Domination (Combo piece, utility)
• Ancient Greenwarden (Doubles landfall triggers, enables recursion)

Attribute Ratings:

Speed: 7/10

• Can threaten wins via combat/combo as early as T5-6 with optimal ramp and untap synergies, but lacks T4 wins common in higher tiers.

Resilience: 8/10

• Exceptional recovery via land recursion, card draw, and Derevi's tax avoidance. Multiple redundancy pieces for key effects mitigate disruption.

Consistency: 8/10

• High density of tutors (Enlightened, Mystical, Green Sun's Zenith, Crop Rotation), card draw engines (Aesi, Mystic Remora), and functional redundancy (land ramp, recursion) ensure reliable access to core strategy.

Interaction: 7/10

• Runs efficient counterspells (Force of Will, Mental Misstep), targeted removal (Swords, Beast Within), and board wipes (Farewell). Lacks stack interaction for resolved noncreature permanents beyond bounce.

Rating Justification:

This deck achieves T5-6 wins consistently through potent land synergies and combos, supported by high resilience and tutor density. While interaction is strong, it lacks the speed and protection to compete with cEDH's fastest decks, placing it firmly in the Focused Competitive tier.

Power level: 7.0 - 7.5
