Overview:

The Necrobloom deck leverages landfall synergies, token generation, and graveyard recursion to overwhelm opponents. It combines incremental value from land drops with explosive token production via cards like Field of the Dead, Avenger of Zendikar, and Scute Swarm, supported by land-cheating engines like Burgeoning and Exploration. While lacking cEDH-tier combos, it can achieve critical mass through Phyrexian Altar/Ashnod's Altar synergies and land-based value engines.

Primer:

Core Strategy:

1. Ramp & Setup: Use 1–2 mana dorks (Birds of Paradise) and land tutors (Three Visits, Knight of the Reliquary) to hit 7+ unique lands quickly.
2. Token Engine: Trigger landfall via The Necrobloom, Scute Swarm, and Felidar Retreat to create Plant/Zombie armies.
3. Graveyard Loops: Dredge lands with The Necrobloom’s ability and recur them via Conduit of Worlds/Ancient Greenwarden for repeated triggers.
4. Finishers: Overwhelm with tokens or combo via Ashaya, Soul of the Wild (turning creatures into land-triggers) + Scute Swarm for exponential growth.

Key Lines:

• Ashaya + Scute Swarm: Casting creatures with Ashaya in play treats them as lands, triggering Scute Swarm’s copy effect recursively.
• Field of the Dead + Dryad of the Ilysian Grove: Guarantee 7+ unique land types for consistent Zombie generation.
• Altar Loops: Sac tokens to Phyrexian Altar for mana to fuel Cultivator Colossus or Dread Return recursion.

Mulligan Priorities:

• Keep hands with 3 lands, 1–2 ramp pieces, and a land tutor/engine (e.g., Elvish Reclaimer).
• Prioritize color fixing (fetchlands, Dryad of the Ilysian Grove) to enable consistent landfall triggers.

Weaknesses:

Critical:

• Graveyard Hate: Rest in Peace/Leyline of the Void cripples dredge recursion and token enablers like Turntimber Sower.
• Mass Removal: Vanquish the Horde/Damnation reset token boards with minimal recovery tools.

Moderate:

• Land Destruction: Relies on land density; Armageddon-effects disrupt engines.
• Commander Reliance: Losing The Necrobloom repeatedly weakens dredge consistency.

Most Important Cards:

• Field of the Dead
• Ashaya, Soul of the Wild
• Phyrexian Altar
• Scute Swarm
• Ancient Greenwarden
• Dryad of the Ilysian Grove
• Avenger of Zendikar
• Burgeoning
• The Gitrog Monster
• Conduit of Worlds

Attribute Ratings:

Speed: 6/10

• Can establish token dominance by T5–6 with optimal draws. Lacks T3–4 combos but accelerates via land-cheating.

Resilience: 5/10

• Vulnerable to graveyard hate and wipes but has redundancy in land engines (Exploration, Burgeoning).

Consistency: 7/10

• 10+ land tutors, 8+ landfall payoffs, and graveyard recursion ensure steady value.

Interaction: 5/10

• Moderate spot removal (Swords to Plowshares, Assassin's Trophy) but lacks free counterspells or stax.

Rating Justification:

This deck sits between "Optimized Casual" and "Focused Competitive" tiers. It generates overwhelming value by T6–7 but lacks the speed (T5–6 wins) and interaction density of higher tiers. Its reliance on combat and incremental value aligns with Power Level 6.0–6.5, comparable to focused EDH decks with clear synergies but no Tier 1 combos.

Power level: 6.0–6.5
