Overview:

This Miirym, Sentinel Wyrm deck is a Dragon tribal build focused on explosive value through token copies and combat overkill. The strategy revolves around casting high-impact Dragons to trigger Miirym's duplication ability, supported by cost reduction, treasure generation, and damage amplifiers. While lacking infinite combos, the deck can generate overwhelming board states through multiplicative Dragon synergies like Dragon Tempest and Scourge of Valkas, with backup from conditional counterspells and midrange card draw.

Primer:

Core Strategy:
Deploy Miirym by T4-5 using mana rocks and land ramp, then chain Dragon drops to create exponential value. Key phases:

1. Setup (T1-4): Use Llanowar Elves, Cultivate, and cost reducers to accelerate. Protect Miirym with Rhythm of the Wild anti-counter tech.
2. Engine Activation (T5+): Cast Dragons with ETB/damage triggers. Goldspan Dragon/Savage Ventmaw generate treasures to fuel more threats. Thrakkus the Butcher doubles power for lethal swings.
3. Overrun: Convert Dragon tokens into damage via Atarka, World Render double strike and Dragon Tempest burn. Use Garruk's Uprising draws to refuel.

Mulligan Priorities:

• 3 lands with green/red sources
• 2+ ramp pieces (Sol Ring/Dragonlord's Servant ideal)
• At least 1 Dragon or protection (Stubborn Denial)
  Reject hands without early mana acceleration.

Key Tips:

• Sequence Dragons by mana value - play cheaper ones first to enable Earthquake Dragon discounts
• Save Unleash Fury for Miirym or Drakuseth, Maw of Flames combat steps
• Use Haven of the Spirit Dragon recursion strategically against removal-heavy pods

Avoid Traps:

• Overextending into board wipes before establishing recursion
• Keeping high-CMC hands without cost reducers
• Wasting removal on non-critical threats

Weaknesses:

Critical:

• Heavy commander reliance (3+ removals cripple strategy)
• Limited stack interaction (only 5 counterspells)

Moderate:

• Slow recovery from board wipes
• Minimal graveyard recursion

Minor:

• Vulnerable to Blood Moon effects (only basic land fixing)

Most Important Cards:

• Dragon Tempest
• Scourge of Valkas
• Goldspan Dragon
• Thrakkus the Butcher
• Garruk's Uprising
• Dragon's Hoard
• Savage Ventmaw
• Atarka, World Render
• Crucible of Fire
• Temple of the False God

Attribute Ratings:

Speed: 5/10

• Typical T5 Miirym -> T6+ Dragon chains. High-cost threats require setup turns.

Resilience: 4/10

• Weak to targeted removal on Miirym. Some recursion (Haven of the Spirit Dragon) but slow.

Consistency: 6/10

• 8 cost reducers + 12 card draw engines provide redundancy. Lacks tutors for key pieces.

Interaction: 5/10

• 10 targeted removals + 5 counterspells. Mostly reactive with limited board wipes.

Rating Justification:

This deck sits between "Optimized Casual" (5.0) and "High-Power Casual" (5.5) on the rubric. It can consistently threaten T8-10 kills through combat/damage triggers but lacks:
1) The speed of T6-7 combo decks
2) Free interaction/protection for higher tiers
3) True stax/resource denial locks

The focused Dragon synergy and explosive token generation outclass precons but fold to dedicated control.

Power level: 5.0 - 5.5
