Overview:

This 5-color Dragon tribal deck leverages The Ur-Dragon's cost reduction and card advantage to deploy high-impact Dragons rapidly. The primary strategy involves ramping into massive flying threats, utilizing combat damage supplemented by extra combat phases (All-Out Assault, Relentless Assault) and Dragon synergies. Secondary win conditions include planeswalker ultimates (Nicol Bolas, Planeswalker, Sivitri, Dragon Master) and overwhelming value from ultimatums (Genesis Ultimatum, Ruinous Ultimatum). The Ur-Dragon is essential as both an enabler (cost reduction, card draw) and a finisher, though its high recast cost makes it vulnerable to removal. Morophon, the Boundless acts as a "hidden commander" for explosive Dragon chains.

Primer:

Core Strategy Execution:

1. Early Ramp (Turns 1-4): Deploy signets (Golgari Signet, Rakdos Signet), Chromatic Lantern, or land-fetching enchantments (Encroaching Dragonstorm). Use rituals (Dark Ritual, Seething Song) for early bursts. Prioritize fixing with tri-lands and Command Tower.
2. Mid-Game Threats (Turns 4-6): Cast discounted Dragons like Atarka, World Render, Vorosh, the Hunter, or Ureni, the Song Unending. Leverage The Ur-Dragon's attack trigger to cheat permanents (e.g., Progenitus) or refill hand. Use Metallic Mimic/Dragonstorm Globe for counters.
3. Win Condition Execution (Turns 6-8):
   • Combat: Swing with Dragons boosted by Atarka, World Render (double strike), Garruk's Uprising (trample), or extra combat spells. Karakyk Guardian provides evasion protection.
   • Value Overload: Resolve ultimatums or Parallel Thoughts for game-winning card advantage. Activate Kenrith, the Returned King abilities for repeated recursion/counters.
   • Planeswalkers: Protect Nicol Bolas, Planeswalker or Sivitri, Dragon Master to unleash devastating ultimates.

Mulligan Priorities:

• Keep hands with 3+ lands including color fixing (e.g., tri-lands, Command Tower).
• Prioritize early ramp (signets, Arcane Signet, Lotus Bloom) or cost reducers (Morophon, the Boundless).
• Ensure at least one Dragon or Dragon tutor (Diabolic Tutor, Sivitri's -3) by turn 4.
• Avoid hands lacking green/black for ramp/fixing or with only high-CMC spells.

Key Tips:

• Sequence Cost Reduction: Cast Morophon, the Boundless naming Dragons before deploying other threats for massive discounts.
• Protect Key Engines: Use Bant Charm, Golgari Charm, and New Way Forward to shield The Ur-Dragon or planeswalkers.
• Exploit Attack Triggers: Attack with multiple Dragons simultaneously to maximize The Ur-Dragon's draw/cheat effect. Thunderclap Wyvern boosts flying team.
• Recursion: Bladewing the Risen and Auroral Procession retrieve critical Dragons/answers from the graveyard.

Weaknesses:

Critical

• Slow Mana Base: Heavy reliance on tapped duals/tri-lands (10+), delaying threats and interaction until mid-game.
• Board Wipe Vulnerability: Minimal protection against wipes (e.g., Cleansing Nova); high-CMC Dragons hinder recovery.
• Anti-Synergy Hate: Cursed Totem/Linvala cripples Kenrith, Ramos, Dragon Engine, and mana rocks.

Moderate

• Graveyard Reliance: Recursion strategies (Bladewing, Auroral Procession) fold to Rest in Peace.
• Combo Weakness: Struggles against faster combo decks due to limited stack interaction (only 3 counterspells).
• Color-Intensive Spells: Niv-Mizzet, Parun/Crux of Fate demand heavy pip commitment, straining fixing.

Minor

• Artifact/Enchantment Dependence: Key ramp (signets, Gilded Lotus) and engines (Whirlwind of Thought) are soft to mass removal.
• Life Total Pressure: Aggressive decks can exploit early life loss from painlands/rituals before Dragons stabilize.

Most Important Cards:

• The Ur-Dragon (Cost reduction, card advantage, win enabler)
• Morophon, the Boundless (Free Dragons, tribal synergy)
• Atarka, World Render (Combat finisher with double strike)
• Genesis Ultimatum (Game-winning value surge)
• Chromatic Lantern (Critical mana fixing)
• Kenrith, the Returned King (Recursion, counters, card draw)
• Ramos, Dragon Engine (Mana battery for ultimatums)
• Parallel Thoughts (Guaranteed card quality)
• Diabolic Tutor (Finds key pieces/answers)
• Encroaching Dragonstorm (Ramp and Dragon synergy)

Attribute Ratings:

Speed: 6/10

• Capable of T7-8 wins via combat or ultimatums with ideal ramp, but inconsistent early pressure due to tapped lands and high average CMC (4.2).

Resilience: 5/10

• Limited protection/recursion for key pieces; relies on reactive interaction that may not scale in multiplayer. Recovers poorly from early wipes.

Consistency: 6/10

• Strong card advantage engines (Ur-Dragon, Draconic Lore, planeswalkers) and tutors offset variance, but mana base inconsistencies hinder reliability.

Interaction: 5/10

• Targeted removal (Bant Charm, Inevitable Defeat) and board wipes (Crux of Fate, Cleansing Nova) are present but inefficient against fast combos. Minimal counterspells.

Rating Justification:

The deck achieves T7-8 wins through combat or value overloads with solid consistency, fitting the "Optimized Casual" tier (5.0-5.5). However, its tapped mana base and vulnerability to early disruption prevent higher resilience/speed. Power level reflects strong tribal synergy balanced by inherent 5-color fragility.

Power level: 5.0 - 5.5
