Overview:

This Naya (RGW) lands-matter deck revolves around Yuma, Proud Protector, leveraging land sacrifice and recursion to fuel card advantage, token generation, and explosive combat finishes. The strategy focuses on turbo-charging landfall triggers with recursion engines like Crucible of Worlds and Ancient Greenwarden, while sacrificing Deserts to Yuma's ability to create 4/2 Plant Warrior tokens. Key payoffs include Omnath, Locus of Rage for elemental swarms, Craterhoof Behemoth for alpha strikes, and Moraug, Fury of Akoum for extra combats. Yuma acts as both a value engine (land-to-card conversion) and a token generator, though the deck can function through alternative land recursion engines if the commander is unavailable.

Primer:

Core Strategy Execution:

1. Early Setup (T1-4):
   • Ramp with land-fetching spells (Harrow, Three Visits, Azusa, Lost but Seeking) and self-mill (Greenseeker, Dune Chanter).
   • Sacrifice utility lands (Evolving Wilds, Wasteland) to fuel Yuma's cost reduction and trigger early Titania, Protector of Argoth/Desert token generation.

2. Midgame Engine (T4-7):

   • Deploy recursion engines (Ramunap Excavator, Conduit of Worlds) to replay sacrificed lands.
   • Activate landfall payoffs: Scute Swarm token multiplication, Omnath, Locus of Rage elemental generation, and Ancient Bronze Dragon counter distribution.
   • Use Scapeshift or Realms Uncharted to mass-dump lands into the graveyard, enabling Yuma’s cost reduction to cast her for {G}{W} or less.

3. Win Condition Execution:

   • Combat Overkill: Deploy Craterhoof Behemoth or Starlight Spectacular with a wide board of Plants/Elementals.
   • Moraug Infinite Combats: Pair Ancient Greenwarden with fetchlands/Ghostway to trigger multiple landfall instances per turn, enabling endless combat phases.
   • Burn: Sacrifice Deserts to Ramunap Ruins or Sunscorched Desert for direct damage.

Mulligan Priorities:

• Keep hands with 2-3 lands, including at least one land-fetching spell (Nature's Lore, Farseek).
• Prioritize early enablers: Crucible of Worlds, Ramunap Excavator, or Greenseeker.
• Avoid hands without land recursion or ramp in slow metas.

Key Tips:

• Use Ghostway defensively to dodge wraths or offensively to retrigger ETB effects (e.g., Titania, Protector of Argoth, Ancient Bronze Dragon).
• Zuran Orb converts excess lands into life while fueling Yuma’s draw ability.
• The Ozolith preserves +1/+1 counters from sacrificed Bristly Bill, Spine Sower or Ancient Bronze Dragon triggers.

Weaknesses:

Critical

• Graveyard Reliance: Rest in Peace or Leyline of the Void cripples land recursion and Yuma’s cost reduction.
• Board Wipes: Blasphemous Act or Farewell resets token-based strategies with minimal recovery tools.

Moderate

• Stax Effects: Blood Moon disrupts nonbasic Desert synergies; Root Maze slows land recursion.
• Spot Removal on Engines: Killing Ancient Greenwarden or Crucible of Worlds delays the deck’s momentum.

Minor

• Slow Mana Base: Many Deserts enter tapped, delaying early plays.
• Limited Stack Interaction: Relies on Boros Charm and Heroic Intervention for protection instead of counterspells.

Most Important Cards:

1. Crucible of Worlds (Land recursion backbone)
2. Ancient Greenwarden (Double landfall triggers + recursion)
3. Scapeshift (Mass land sacrifice for Yuma discount + triggers)
4. Craterhoof Behemoth (Primary combat finisher)
5. Titania, Protector of Argoth (Token generation + land recursion)
6. Moraug, Fury of Akoum (Extra combats with landfall)
7. Omnath, Locus of Rage (Token generation + burn)
8. The Great Henge (Card draw + counter synergy)
9. Ramunap Excavator (Redundant land recursion)
10. Doubling Season (Token/counter amplification)

Attribute Ratings:

Speed: 6/10

• Can threaten wins via Craterhoof/Moraug combats by T7-8, but lacks fast mana for earlier explosive plays.

Resilience: 5/10

• Recursion engines provide recovery, but over-reliance on graveyard and tokens makes it vulnerable to hate.

Consistency: 7/10

• Abundant land tutors (12+), card draw from Yuma/Sylvan Library, and redundant recursion ensure key pieces are accessible.

Interaction: 4/10

• Limited to spot removal (Swords to Plowshares, Force of Vigor) and combat tricks; struggles against spell-based combos.

Rating Justification:

This deck operates at a T7-8 win pace with resilient land engines but falters against common graveyard/artifact hate. Its combat-focused wins and moderate interaction align with the "Optimized Casual" tier, while its vulnerability to stax keeps it below high-power thresholds.

Power level: 5.0 - 5.5
