Overview:

This Selesnya (G/W) deck helmed by Gylwain, Casting Director combines stax elements, enchantress synergies, and compact infinite combos. The primary strategy leverages Gylwain's Role token generation to fuel enchantment-based value engines while deploying disruptive creatures. Secondary win conditions include infinite life/damage via Heliod, Sun-Crowned + Walking Ballista, infinite mana with Devoted Druid + Vizier of Remedies, and combat wins amplified by aura stacking. Gylwain acts as a value engine rather than a critical combo piece, enabling card draw via Sorcerer Roles and buffing creatures with Monster/Royal Roles.

Primer:

Core Strategy Execution:

1. Early Disruption (Turns 1-3): Deploy mana acceleration (Mana Crypt, Birds of Paradise) and stax pieces (Drannith Magistrate, Deafening Silence). Use Land Tax or Sylvan Scrying to fix mana.
2. Mid-Game Setup (Turns 3-5): Cast Gylwain to generate Role tokens, then chain enchantress effects (Enchantress's Presence, Sterling Grove). Tutor for combo pieces (Heliod, Sun-Crowned, Walking Ballista) or key auras (All That Glitters).
3. Win Conditions (Turns 4-7):
   • Combo: Resolve Heliod, Sun-Crowned + Walking Ballista (infinite damage) or Devoted Druid + Vizier of Remedies (infinite mana into Finale of Devastation).
   • Combat: Pump creatures using auras like Ancestral Mask and Ethereal Armor, supported by Role token buffs.
   • Stax Lock: Combine Linvala, Keeper of Silence + Collector Ouphe to disable opponents' activated abilities.

Mulligan Priorities:

• Keep hands with 2-3 lands (including duals/fetches) and at least one mana dork/stax piece.
• Prioritize early interaction (Swords to Plowshares, Veil of Summer) or tutors in removal-heavy metas.
• Avoid hands lacking ramp or with only high-CMC cards.

Key Tips:

• Use Sterling Grove and Greater Auramancy to protect critical enchantments.
• Sanctum Weaver scales with enchantment count for explosive mana.
• The Ozolith preserves +1/+1 counters from Roles/Heliod when creatures die.

Weaknesses:

Critical

• Vulnerable to Toxic Deluge/Farewell due to reliance on creature-based combos and auras.
• Stony Silence/Collector Ouphe shuts off artifact mana and Walking Ballista.

Moderate

• Graveyard hate (Rest in Peace) disrupts Eternal Witness and Finale of Devastation recursion.
• Back to Nature/Cleansing Nova can wipe multiple enchantments.

Minor

• Struggles against hexproof/shroud if aura targets are limited.
• Blood Moon impacts nonbasic land-heavy mana base.

Most Important Cards:

• Heliod, Sun-Crowned (Infinite damage/life combo)
• Walking Ballista (Primary combo payoff)
• Devoted Druid (Infinite mana enabler)
• Vizier of Remedies (Combo piece for Devoted Druid)
• Enlightened Tutor (Tutors combo/stax pieces)
• Sterling Grove (Protects enchantments, tutors)
• Mana Crypt (Explosive early mana)
• Finale of Devastation (Tutor/win condition)
• Drannith Magistrate (Stax against commanders)
• Sanctum Weaver (Scaling mana generation)

Attribute Ratings:

Speed: 8/10

• Capable of T3-4 wins with fast mana into combos, averaging T5-6 in optimized draws.

Resilience: 6/10

• Multiple protection spells (Teferi's Protection, Veil of Summer) and stax to slow opponents, but combos remain fragile to targeted removal.

Consistency: 7/10

• 10+ tutors and enchantress draw engines ensure frequent access to key pieces, though some combo lines lack redundancy.

Interaction: 7/10

• Robust suite of targeted removal (Swords to Plowshares, Force of Vigor) and stax effects, but limited stack interaction outside Silence.

Rating Justification:

This deck operates at high-power casual levels with cEDH-adjacent speed (T3-4 potential) via compact combos and premium mana acceleration. However, its reliance on creature-based win conditions and vulnerability to board wipes caps its resilience below top-tier competitive decks.

Power level: 7.0 - 7.5
