Overview:

This Sythis, Harvest's Hand deck is a high-synergy enchantress build that leverages its commander's card draw engine to assemble value engines and win conditions. The strategy revolves around casting enchantments to generate card advantage, life gain, and mana acceleration, eventually winning through infinite combos or overwhelming board states. Sythis serves as the core engine, enabling explosive draw power while synergizing with 40+ enchantments. Key win conditions include the Heliod, Sun-Crowned + Walking Ballista combo, Aetherflux Reservoir life-to-damage conversion, and token overruns via Hallowed Haunting/Elesh Norn, Grand Cenobite.

Primer:

Core Strategy Execution:

1. Early Game Setup (T1-3):
   • Prioritize mana acceleration (Utopia Sprawl, Wild Growth, Arbor Elf + Overgrowth).
   • Deploy enchantress effects (Argothian Enchantress, Enchantress's Presence) for card draw.
   • Establish stax/control elements (Drannith Magistrate, Root Maze) to slow opponents.

2. Mid-Game Engine (T4-6):

   • Activate explosive mana generators (Serra's Sanctum, Nykthos, Shrine to Nyx with high enchantment count).
   • Tutor for combo pieces (Heliod, Sun-Crowned via Worldly Tutor, Aetherflux Reservoir via Enlightened Tutor).
   • Generate massive life gain through Sythis triggers and Carpet of Flowers/Smothering Tithe.

3. Win Condition Execution:

   • Infinite Life/Damage: Heliod + Walking Ballista (requires Cloudstone Curio/Meticulous Excavation to bounce/recast Ballista).
   • Aetherflux Nuke: Cast 10+ spells in a turn with Earthcraft/Sanctum Weaver mana.
   • Token Overrun: Hallowed Haunting spirit army amplified by Elesh Norn or Finale of Devastation.

Mulligan Priorities:

• Keep hands with at least 1 enchantress effect, 1 mana accelerator, and 2 lands.
• Prioritize Serra's Sanctum/Gaea's Cradle with Sylvan Scrying/Crop Rotation.
• Avoid hands without green mana sources or early plays.

Key Tips:

• Use Sterling Grove to protect key enchantments while tutoring.
• Cloudstone Curio enables infinite ETBs with 1-cost enchantments like Flickering Ward.
• Teferi's Protection protects against board wipes during critical turns.

Weaknesses:

Critical

• Crippled by mass enchantment removal (Cleansing Nova, Austere Command).
• Lacks instant-speed interaction for stack-based combos (only Silence/Grand Abolisher).

Moderate

• Struggles against Stony Silence/Collector Ouphe shutting off artifact mana.
• Rest in Peace disrupts recursion from Hall of Heliod's Generosity.

Minor

• Limited flying defense pre-Hallowed Haunting.
• Blood Moon effects disrupt nonbasic mana base.

Most Important Cards:

• Serra's Sanctum (Mana explosion for combo turns)
• Heliod, Sun-Crowned (Primary combo piece)
• Aetherflux Reservoir (Alternate win condition)
• Earthcraft (Mana engine/combo enabler)
• Sterling Grove (Protection + tutoring)
• Enlightened Tutor (Finds key artifacts/enchantments)
• Cloudstone Curio (Enables infinite ETB loops)
• Sanctum Weaver (Scaling mana with enchantments)
• Finale of Devastation (Tutor/Overrun finisher)
• Elesh Norn, Grand Cenobite (Board control + finisher)

Attribute Ratings:

Speed: 6/10

• Can threaten T5-7 wins with ideal draws (Heliod+Ballista/Aetherflux activation) but lacks fast mana for earlier combos.

Resilience: 7/10

• Strong protection suite (Greater Auramancy, Teferi's Protection) and recursion (Hall of Heliod's Generosity), but folds to repeated enchantment wipes.

Consistency: 8/10

• 12 enchantress effects, 7 tutors, and massive draw power ensure reliable access to key pieces.

Interaction: 5/10

• Targeted removal via Darksteel Mutation/Song of the Dryads and stax pieces, but minimal stack interaction outside Silence.

Rating Justification:

This deck demonstrates focused optimization with multiple combo lines and strong consistency, but its reliance on sorcery-speed setups and vulnerability to enchantment hate caps its speed below cEDH thresholds. The ability to consistently threaten T7-8 wins through combat or combos aligns with the "Focused" tier.

Power level: 6.0 - 6.5
