Overview:

This Azorius flying tribal deck helmed by Errant and Giada focuses on deploying evasive creatures with flash/flying, amplifying their combat potential through anthems, and generating card advantage through combat damage triggers. The commander enables casting key spells from the top of the library while providing flash synergy. The primary win condition is overwhelming opponents with buffed flying creatures, supported by light control elements and selective recursion.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4):
   • Deploy mana rocks (Azorius Signet, Talisman of Progress) and cost-reduction enablers like Warden of Evos Isle.
   • Cast flash/flying creatures like Spectral Sailor or Judge's Familiar to maintain interaction.
   • Establish card advantage engines early with Bident of Thassa or Reconnaissance Mission.

2. Midgame Development (Turns 4-6):

   • Cast anthem effects (Favorable Winds, Gravitational Shift) to boost flying threats.
   • Use Errant and Giada to cast flyers/flash spells from the top of the library for tempo advantage.
   • Deploy finishers like Sephara, Sky's Blade (using her cost-reduction ability) or Steel-Plume Marshal for combat spikes.

3. Late Game/Closing:

   • Activate Rally of Wings for surprise lethal damage.
   • Protect the board with Linvala, Shield of Sea Gate or Selfless Spirit.
   • Leverage Windreader Sphinx and Thunderclap Wyvern for sustained pressure.

Mulligan Priorities:

• Keep hands with 2-3 lands and at least one mana rock or cost reducer.
• Prioritize early interaction (Swords to Plowshares, Negate) or card advantage engines.
• Avoid hands lacking flying creatures or with only high-CMC spells.

Key Tips:

• Use Errant and Giada's top-deck casting to bypass hand limitations and maintain momentum.
• Time Wipe can be a one-sided board wipe if you return a creature to hand.
• Malcolm, Alluring Scoundrel provides incremental value and potential free spells in later turns.

Weaknesses:

Critical

• No mass artifact/enchantment removal – Relies solely on Austere Command and Cathar Commando for key threats like Cursed Totem.
• Fragile to flying hate – Sandwurm Convergence or Plummet effects cripple the primary strategy.

Moderate

• Limited ramp – Only 6 mana rocks and no land-based acceleration beyond Myriad Landscape.
• Vulnerable to wide boards – Minimal sweepers beyond Supreme Verdict and Time Wipe.

Minor

• Low individual threat quality – Many creatures are 1-3 power flyers requiring anthem support.
• No infinite combos – Relies entirely on combat for wins.

Most Important Cards:

• Errant and Giada (Strategy enabler, card advantage)
• Sephara, Sky's Blade (Indestructible shield + finisher)
• Gravitational Shift (Asymmetric combat buff)
• Bident of Thassa (Primary card engine)
• Supreme Verdict (Uncounterable reset)
• Favorable Winds (Key anthem effect)
• Rally of Wings (Surprise lethal enabler)
• Linvala, Shield of Sea Gate (Protection/control)
• Donal, Herald of Wings (Token generator/value multiplier)
• Thunderclap Wyvern (Anthem + flash synergy)

Attribute Ratings:

Speed: 4/10

• Wins typically occur around T8-10 through gradual combat pressure. Limited fast mana and no combos cap early lethality.

Resilience: 5/10

• Moderate protection (Selfless Spirit, counterspells) but struggles to rebuild after multiple wipes.

Consistency: 6/10

• Redundant anthem effects and flying synergy, but lacks tutors for key pieces like Gravitational Shift.

Interaction: 7/10

• Strong targeted removal (Path to Exile, Generous Gift) and counterspells (Dovin's Veto, Lofty Denial), but limited stack control.

Rating Justification:

This deck operates as a focused casual build with clear combat-focused win conditions and moderate interaction. Its T8-10 win clock and reliance on creature synergies place it slightly above precon level, but the lack of fast mana or combo finishers limits optimization.

Power level: 4.0 - 4.5
