Overview:

This Sythis, Harvest's Hand deck is a high-powered enchantress build leveraging Sythis's card draw and life gain to fuel synergistic enchantment-based value engines, stax effects, and multiple combo finishes. The commander serves as the critical draw engine and life stabilizer, enabling explosive turns through enchantment chains. Primary win conditions include Aetherflux Reservoir life-based kills, infinite mana combos with Walking Ballista, and overwhelming token generation via Hallowed Haunting/Sigil of the Empty Throne. The deck operates efficiently with low-CMC enchantments and powerful land-based mana acceleration.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Prioritize mana acceleration via land enchantments (Utopia Sprawl, Wild Growth), dorks (Arbor Elf), or burst ramp (Burgeoning, Exploration). Cast Sythis immediately to start drawing off enchantments. Fetch critical lands (Serra's Sanctum, Nykthos, Shrine to Nyx) with Crop Rotation/Sylvan Scrying.
2. Midgame Value Engine (Turns 4-6): Deploy additional enchantress effects (Argothian Enchantress, Setessan Champion) to draw multiple cards per turn. Establish stax pieces (Aura of Silence, Blind Obedience) or protection (Greater Auramancy). Generate tokens with Hallowed Haunting or Squirrel Nest to fuel Earthcraft.
3. Win Condition Execution:
   • Aetherflux Reservoir: Chain low-CMC enchantments with Sythis to gain 30+ life, then snipe opponents.
   • Infinite Mana: Assemble Devoted Druid + Gauntlets of Light (untap Druid infinitely) or Sanctum Weaver + Earthcraft (tap tokens to untap lands). Pump infinite mana into Walking Ballista.
   • Token Overrun: Flood the board with Angels/Spirits via Sigil of the Empty Throne or Hallowed Haunting, then swing with evasion.

Mulligan Priorities:

• Keep hands with Sythis + 1-2 mana accelerants (e.g., Wild Growth + Arbor Elf).
• Prioritize land-searching effects (Crop Rotation, Fertile Ground) if lacking colored sources.
• Reject hands without early plays or excessive high-CMC cards.

Key Tips:

• Use Sterling Grove proactively to tutor or shield enchantments. Sacrifice it in response to wipes.
• Earthcraft enables explosive turns with token generators—tap tokens to untap enchanted lands for massive mana.
• Protect combo turns with Grand Abolisher or Silence. Teferi's Protection dodges board wipes.
• Leverage Replenish/Hall of Heliod's Generosity to recover from enchantment removal.

Weaknesses:

Critical

• Mass Enchantment Removal: Farewell or Cleansing Nova cripples the deck's engine and win conditions with minimal recovery options.
• Anti-Synergy Stax: Torpor Orb nulls ETB draw from enchantresses, while Cursed Totem shuts down Devoted Druid/Sanctum Weaver.

Moderate

• Graveyard Hate: Rest in Peace disrupts Replenish recursion and Eternal Witness loops.
• Land Destruction: Targeting Serra's Sanctum/Nykthos significantly slows mana generation.

Minor

• Focused Flyers: Evasive threats can pressure life total before Aetherflux stabilizes.
• Stack Interaction: Limited counterspells make resolving key non-enchantment spells (Aetherflux, Walking Ballista) vulnerable.

Most Important Cards:

• Sanctum Weaver (Mana engine/combo piece)
• Earthcraft (Mana multiplier/combo enabler)
• Aetherflux Reservoir (Primary life-based win condition)
• Sterling Grove (Tutor and protection)
• Hallowed Haunting (Token generation and evasion)
• Serra's Sanctum (Explosive mana source)
• Enlightened Tutor (Key artifact/enchantment fetch)
• Survival of the Fittest (Creature tutor for combo pieces)
• Replenish (Graveyard recovery)
• Devoted Druid (Infinite mana combo piece)

Attribute Ratings:

Speed: 8/10

• Consistently threatens T4-5 wins with ideal draws (e.g., T1 ramp → T2 Sythis → T3-4 Aetherflux/combos), leveraging efficient mana acceleration and tutors.

Resilience: 6/10

• Recursion (Replenish, Hall of Heliod) and protection (Teferi's Protection, shroud effects) mitigate disruption, but heavy reliance on enchantments creates vulnerability to mass removal.

Consistency: 8/10

• 10+ enchantress effects, 7 tutors, and Sythis's draw engine ensure reliable access to combo pieces and value generators.

Interaction: 7/10

• Robust targeted removal (Grasp of Fate, Seal of Cleansing), stax (Blind Obedience), and stack control (Silence, Grand Abolisher), though lacks broad counterspells.

Rating Justification:

This deck operates at cEDH-viable speeds with T4-5 win potential through redundant combos and exceptional consistency, but its enchantment-centric board state and reliance on non-creature permanents create critical vulnerabilities to mass removal that prevent higher resilience. It aligns with High Power (T3-4 win/lock) but falls short of cEDH's near-unbreakable stability.

Power level: 8.0 - 8.5
