Overview:

This Temur Dragon tribal deck revolves around Miirym, Sentinel Wyrm, leveraging its ability to create non-legendary token copies of Dragons for explosive value. The strategy focuses on casting high-impact Dragons to trigger Miirym's duplication, generating overwhelming board states through ETB damage (e.g., Scourge of Valkas), token armies (Lathliss, Dragon Queen), and Treasure synergies (Ganax, Astral Hunter). Miirym acts as the linchpin, amplifying every Dragon’s impact, while secondary themes include dungeon/initiative payoffs and flicker effects (Ghostly Flicker, Sword of Hearth and Home) to reuse ETBs.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Prioritize ramp (Cultivate, Farseek, Scaled Nurturer) and cost reducers (Dragonspeaker Shaman, Herald's Horn). Deploy value engines like Garruk's Uprising or Temur Ascendancy for card draw.
2. Commander Deployment (Turns 5-6): Cast Miirym with protection (Lightning Greaves, Tyvar's Stand). Use Haven of the Spirit Dragon or Cursed Mirror (copying a mana dork) to accelerate.
3. Value Engine (Turns 6+): Drop Dragons with ETB damage (Bogardan Hellkite, Thunder Dragon), token generators (Dragon Broodmother), or card advantage (Iymrith, Desert Doom). Miirym doubles these effects, creating massive board states.
4. Win Conditions:
   • Combat Overload: Swarm with Dragon tokens from Miirym/Lathliss, enhanced by Dragon Tempest haste and Pathbreaker Ibex-like effects (missing in the list but implied via power scaling).
   • ETB Burn: Stack triggers from Scourge of Valkas, Dragon Tempest, and Keiga, the Tide Star to deal lethal damage.
   • Initiative Dungeons: Avenging Hunter and Loot Dispute provide incremental value and a late-game 5/5 Dragon token payoff.

Mulligan Priorities:

• Keep hands with 3+ lands (including color fixing), 1-2 ramp spells, and at least one Dragon or card draw engine.
• Prioritize early protection (Stubborn Denial, Keep Safe) in interactive metas.
• Avoid hands with only high-CMC Dragons and no ramp.

Key Tips:

• Use flicker effects (Ghostly Flicker, Essence Flux) on Dragons with ETBs to generate additional tokens via Miirym.
• Sword of Hearth and Home doubles as ramp and flicker enabler.
• Save counterspells for board wipes or key stax pieces.

Weaknesses:

Critical

• Board Wipes: Lacks mass recursion; rebuilds slowly after Wrath of God effects.
• Commander Reliance: Miirym’s 6 CMC makes recasting prohibitive after repeated removal.
• Anti-Token Tech: Torpor Orb/Hushbringer nullifies Miirym’s token generation and ETBs.

Moderate

• Artifact/Enchantment Hate: Vulnerable to Bane of Progress disrupting key pieces like Dragon’s Hoard or Herald’s Horn.
• Mana Constraints: Limited fast mana; high-CMC Dragons risk getting stuck in hand.

Minor

• Graveyard Interaction: Minimal recursion beyond Haven of the Spirit Dragon.
• Fliers/Reach: Struggles against decks with superior air defense.

Most Important Cards:

• Miirym, Sentinel Wyrm (Core enabler for token duplication)
• Scourge of Valkas (Scaling ETB burn with Dragon count)
• Dragon Tempest (Haste enabler + burn amplifier)
• Lathliss, Dragon Queen (Token swarm generator)
• Ganax, Astral Hunter (Treasure synergy for ramp/combat tricks)
• Ghostly Flicker (ETB recursion and token doubling)
• Temur Ascendancy (Card draw + haste)
• Sword of Hearth and Home (Protection, flicker, and ramp)
• Herald's Horn (Cost reduction + card advantage)
• Garruk's Uprising (Trample + card draw)

Attribute Ratings:

Speed: 5/10

• Can deploy threats by turn 5-6, but lacks fast mana or T4 combos. Relies on incremental value.

Resilience: 4/10

• Limited protection for Miirym and key pieces. Recovery from board wipes is slow.

Consistency: 6/10

• Moderate card draw and cost reducers, but few tutors for critical Dragons.

Interaction: 5/10

• Reactive counterspells (Arcane Denial) and targeted removal (Bolt Bend), but lacks board wipes.

Rating Justification:

This deck operates as a synergistic Dragon tribal build with a clear T6-8 combat/ETB burn win path, but its reliance on a high-CMC commander and vulnerability to common disruption caps its ceiling. It fits into the Casual/Precon to Focused Casual range, excelling in battlecruiser metas but folding to faster or more interactive strategies.

Power level: 4.0 - 5.0
