Overview:

This Scion of the Ur-Dragon deck focuses on Dragon tribal synergy, leveraging the commander's ability to tutor Dragons into the graveyard and copy them for explosive combat turns. The strategy combines cost reduction, token duplication, and graveyard recursion to overwhelm opponents with massive flying threats.

Primer:

Core Strategy:
Deploy Scion early (T4-5 with ramp) to stock the graveyard with key Dragons like Thrakkus the Butcher and Miirym, Sentinel Wyrm. Use reanimation (Bladewing the Risen, Patriarch's Bidding) and token duplication to create overwhelming board states. Alternate wincons include Call the Spirit Dragon counters and Dragon Tempest damage triggers.

Key Phases:

1. Ramp & Setup: Prioritize cost reducers (Acolyte of Bahamut, Dragonlord's Servant) and land fetch (Cultivate, Farseek).
2. Graveyard Stocking: Use Scion's ability to dump key Dragons like Broodcaller Scourge or Atarka, World Render.
3. Explosive Turns: Reanimate multiple Dragons simultaneously or cast them with discounts, then trigger combat multipliers (Thrakkus) and haste enablers (Carnelian Orb of Dragonkind).

Mulligan Priorities:

• Keep hands with 3+ lands and 1-2 ramp spells.
• Prioritize color-fixing (tri-lands, Fellwar Stone) in opening hands.
• Avoid hands without early Dragons or graveyard setup tools.

Key Tips:

• Protect Scion with Swiftfoot Boots or Jade Orb of Dragonkind hexproof.
• Chain Dragon ETBs with Reflections of Littjara for double value.
• Use Sarkhan, Soul Aflame as a flexible copy of your best Dragon.

Weaknesses:

Critical

• Graveyard Reliance: Fold to Rest in Peace/Leyline of the Void.
• Mana Fragility: 5-color base struggles with early color requirements.

Moderate

• Board Wipe Vulnerability: Limited recursion outside Will of the Abzan.
• Slow Combos: Call the Spirit Dragon requires 5+ turns to win.

Minor

• Limited Interaction: Mostly sorcery-speed removal (Dragon's Prey).

Most Important Cards:

• Miirym, Sentinel Wyrm
• Thrakkus the Butcher
• Dragon Tempest
• Patriarch's Bidding
• Bladewing the Risen
• Rivaz of the Claw
• Jade Orb of Dragonkind
• Reflections of Littjara
• Sarkhan, Soul Aflame
• Call the Spirit Dragon

Attribute Ratings:

Speed: 7/10
Can deploy game-winning boards by T6-7 with cost reducers and Scion activations.

Resilience: 5/10
Graveyard dependency and commander-centric strategy create fragility.

Consistency: 6/10
Moderate tutor density (Ureni of the Unwritten, Scion's ability) but lacks redundant reanimation.

Interaction: 4/10
Reactive tools like Dispelling Exhale are situational; minimal free protection.

Rating Justification:

The deck can execute explosive Dragon swarm turns typical of optimized casual builds (T8-10 wins) but falters against interaction-heavy metas. Its reliance on vulnerable resources (graveyard, commander) caps its ceiling.

Power level: 5.0 - 6.0
