Overview:

This Sythis, Harvest's Hand deck is an enchantress-focused build that leverages constant enchantment casting for card advantage and life gain, transitioning into wins through massive aura-buffed creatures or token armies. While lacking infinite combos, it employs potent synergies like Sanctum Weaver/Nyxbloom Ancient for explosive mana and Ancestral Mask/All That Glitters for lethal commander damage.

Primer:

Core Strategy:
Deploy Sythis immediately to fuel enchantment-based draw engines. Prioritize 1-2 mana ramp enchantments (Wild Growth, Utopia Sprawl) to accelerate into key pieces like Sterling Grove (protection/tutor) and Sanctum Weaver (mana scaling). Transition to midgame by:

1. Building an unblockable threat via Rogue's Passage + voltron auras
2. Generating angel/pegasus tokens with Sigil of the Empty Throne/Archon of Sun's Grace
3. Overwhelming with Beastmaster Ascension-boosted armies

Mulligan Priorities:

• Keep hands with Sythis + 2 lands + 1 ramp enchantment
• Reject hands lacking green sources or enchantment density
• Accept 4-card hands with Boseiju, Who Endures + Enchantress's Presence

Key Interactions:

• Weaver of Harmony copies Sythis/constellation triggers
• Resurgent Belief recurring entire enchantment suites
• Yenna, Redtooth Regent cloning key auras/enchantments

Win Conversion:

• Krosan Verge tutors Rogue's Passage for lethal Sythis/aura carrier
• Hydra's Growth on evasive creature creates 1-2 turn clocks
• Nyxbloom Ancient + land auras enables game-ending Austere Command cycles

Weaknesses:

Critical

• Foldsto enchantment wipes (Cleansing Nova, Farewell)
• No infinite combos for quick wins

Moderate

• Limited stack interaction (only 3 counterspells)
• Token strategies vulnerable to mass removal

Minor

• Basic-heavy mana mitigates blood moon weakness
• Heroic Intervention protects key board states

Most Important Cards:

• Argothian Enchantress
• Sterling Grove
• Sanctum Weaver
• Enchantress's Presence
• Nyxbloom Ancient
• Ancestral Mask
• Sigil of the Empty Throne
• Wild Growth
• Utopia Sprawl
• Heroic Intervention

Attribute Ratings:

Speed: 6/10
Can deploy lethal commander damage by T5-6 with optimal aura draws, but lacks T3-4 combo kills.

Resilience: 5/10
Multiple enchantress effects provide redundancy, but overreliance on non-hexproof permanents and weak to resolved hate.

Consistency: 8/10
11 enchantress effects + 5 tutors ensure constant card flow and threat deployment.

Interaction: 4/10
Limited to targeted removal (6 pieces) and 2 protective instants, struggles against resolved game-warping permanents.

Rating Justification:

This optimized enchantress build sits between high casual and focused competitive tiers due to strong card advantage engines but lack of deterministic wincons.

Power level: 5.5 - 6.5
